But we know that foliage dense enough provide Heavy Obscurement gives effectively gives observers the Blinded condition when trying to see anything in the area. The only way that can be true is if every possible sight line is obstructed by foliage.
So yes, in three dimensions the foliage isn't a "solid block of plant material". But when seen from a distance as a two-dimensional image, the overlapping opaque branches, stems, and leaves fill the entire area. If there were any significant gaps that persisted even 5' into the dense foliage an observer would be able to see a creature at the edge of the dense foliage, which Heavy Obscurement does not permit.
I'm looking out across my backyard, and not more than forty feet away is a clump of trees with large leaves covering its branches which trail to the ground. A person could be standing in the shade among those trees right now. I can't tell, but I have no doubt that if there were such a person, they could see my house just fine by peeking through the small gaps in the leaves in front of them.
It sounds like you envision dense foliage as much less dense than I think the rules require. Even going with your interpretation, however, how can an area of dense foliage be sufficiently opaque to provide Heavy Obscurement to the creatures inside it while simultaneously not sufficiently opaque to provide Heavy Obscurement to creatures beyond it? (That is your position, yes? That a creature/object among the foliage can't be seen, but a creature/object behind the foliage can be?)
Yes, going back to the trees behind my house, even though the leaves and branches are close together enough in many places to obscure the presence of a person among the cluster of trees, there are also gaps large enough that I can see the shape and color of the house behind quite clearly.
It seems to me that you are the one not following your own guidance. You're imagining an area of foliage with gaps big enough to see through and into the area beyond, but then applying the mechanics for Heavy Obscurement even though the presence of such large gaps conflicts with the description of Heavy Obscurement as effectively inflicting the Blinded condition.
There's no contradiction. I really can't see anything in that area. There could be someone up in that tree looking at me, and I would have no idea. Nevertheless, I can see telephone wires traversing the area behind the tree and the sky peeking through the canopy behind that.
I'm not sure there's any way you could word it that would make me understand how anyone could interpret walls as transparent through any reading of RAW or Fluff. It's really outside anything I can get behind. And I've HONESTLY tried to follow your logic, I just haven't been able to.
Ah, I see what you mean. I don't read "can't see" as a mechanical penalty. The penalty is "Fail Perception Checks" and "Have Disadvantage on Attacks", ETC. The rest is story-fluff. And when the mechanics make it seem like you might be able to see a little, to make it make sense, I'm going to say that you see a little, even if you're "effectively blind". To me that means you have all the mechanical penalties of the Blinded condition, but you can see whatever I feel like describing. (Be it shadows, movement, or whatever).
Interesting. In my mind "can't see" is basically the entire point of the Blinded condition, because it fundamentally changes how the character interacts with the game world (plus it's in the name of the condition ). A suddenly (actually) Blinded character no longer knows what the environment looks like (they have to operate from memory), they can't see what actions other creatures are taking (have to rely on hearing alone), don't know the locations of creatures beyond hearing range, etc. To me the rest of the Blinded condition is just details about action resolution.
Of course, how to interpret "can't see" when someone effectively suffers from the Blinded condition with respect to an opaque foreground object but not with respect to a background object it was occulting, that's a 40-page-thread can of worms....
I think this comes from the fact that the creature can MOVE through it (sure, difficult terrain, yadda yadda) without having to hack away at it that makes it seem like it probably had more openings than you might imagine it to - leading back to "can't see WELL" over "can't see AT ALL" being a probable interpretation of "effectively blinded" by Heavy Obscurement.
Sure, but you can move through foliage that dense because the smaller branches and leaves bend away as you move through them, not because there are clear paths and long sight-lines. A line of landscaped bushes, for example, can easily be dense enough to be an opaque area yet let someone push their way through the line between bushes.
@Hriston seems to be arguing that a character in such a line of opaque bushes couldn't be seen, but that the character behind such a line of opaque bushes could be seen. There is support for that in the text of the Heavy Obscurement rules, but since it creates a paradox where the bushes are both an opaque area and not an opaque area, I consider that another place where the vision/darkness/obscurement rules are incomplete and/or contradictory.
Sort of? Maybe a little? It seems to me that it would be the wall itself not its silhouette that would block your vision - though you might see it's silhouette in the story fluff, if that's what you mean. I think it might not be so much that I can't understand how you could come up with a way to make walls transparent by RAW, but it's so far outside what anyone would rule that I can't understand why we'd even talk about it. It makes it hard for my brain to "go there" even if I'm trying to be with you for the intellectual exercise. I really am trying to play along here!
Ok, so in the weeds I've let the overall point of why I'm discussing transparent walls get lost. Thanks! I can address that.
In this thread I've made (several formulations of) one central claim: that the vision/darkness/obscurement (v/d/o) rules are incomplete, and can't be run as-is. From this central claim I've made several derivative claims:
The v/d/o rules are too incomplete to permit a close reading of those rules to resolve whether the darkness created by the Darkness spell is opaque or transparent.
Because spells are theoretically supposed to be self-contained (i.e. only do what they say they do, and no more), the fact that the text of the Darkness spell does not provide sufficient detail to resolve how the transparent interpretation would interact with the incomplete v/d/o rules is evidence that the transparent interpretation was not intended by the designers. (If it was intended to be transparent, the designers could have written the spell more like the 3.5 version.) I think this evidence is particularly strong because the edge cases where the v/d/o rules fall apart (e.g. backlighting) are much more likely to come up with magical darkness that can be summoned into a well-lit area than they are with natural darkness.
Because the rules can't be run as-is, every DM is making choices about how to run the v/d/o rules that depart (to varying degrees) from the small amount of rules text we actually have. If every DM has to make atextual choices, criticizing a DM for a particular atextual choice on the grounds that it is atextual is meaningless.
I've presented a particular contradiction in the v/d/o rules as evidence supporting my central claim that the rule can't be run as-is. That contradiction involves silhouettes: adding silhouettes into the game (atextually, I note) contradicts the Blinded condition by letting observers see creatures that they are effectively Blinded with respect to. Not adding silhouettes would (if taken to an absurd logical consequence) lead to heavily obscured opaque creatures/objects/walls not being able to block vision of well-lit areas behind them.
Obviously no DM is going to go so far as to let observers see through walls just because those walls are in natural darkness. But avoiding that outcome while not allowing creatures/objects/walls to be visible as silhouettes requires making other atextual choices. I've spoilered my description of two examples of other atextual choices a DM could make to be able to run the game without silhouettes and still keep walls opaque.
One example suggested in this thread (I don't remember by who) was to make all silhouettes blobby and not outline the creature/object/wall. That totally works: observers would see a blobby patch of darkness where an a opaque creature/object/wall is located, rather than seeing the creature/object/wall OR seeing whatever the creature/object/wall was concealing. (For a similar effect, see Shadow of Moil.) But blobby silhouettes are definitely atextual.
Another work-around is to allow natural darkness to make opaque creatures effectively transparent, but not allow the same for objects or walls, and just accepting the (lesser) absurdity of transparent creatures. But again, making such an artificial distinction in what can and cannot be seen as a silhouette would be atextual.
So, to recap, I'm discussing the contradiction in the v/d/o rules between the "can't see" wording of the Blinded condition and the ordinary definition of the word "opaque" in the edge case where Heavily Obscured objects/creatures/walls are backlit. I'm using that contradiction as evidence in support of my central claim, that the v/d/o rules are incomplete. (I've offered as evidence another example of a contradiction in the v/d/o rules vis-a-vis the visibility of a character in heavy obscurement vs behind heavy obscurement, but that one seems less controversial.)
I recognize that you view my central claim as uncontested in this thread. However, my interpretation of the views of other posters conflicts with your interpretation. My understanding is that some posters think the v/d/o rules can be run as-is, and may still be arguing that doing so requires the transparent interpretation of the Darkness spell. If I'm wrong, great!
Not being able to be seen clearly is the standard for hiding. For Heavy Obscurement an observer effectively suffers from the Blinded condition, which means the observer "can't see".
I'm looking out across my backyard, and not more than forty feet away is a clump of trees with large leaves covering its branches which trail to the ground. A person could be standing in the shade among those trees right now. I can't tell, but I have no doubt that if there were such a person, they could see my house just fine by peeking through the small gaps in the leaves in front of them.
It doesn't sound like you are effectively suffering from the Blinded condition with respect to seeing things in the area of that clump of trees. It sounds like there might be particular places in that clump of trees where someone could stand where they were behind an opaque object, but to be "dense foliage" it shouldn't matter where exactly the creature is standing--an observer shouldn't be able to see a creature standing anywhere in dense foliage, which requires the opaque foliage to interrupt their line of sight everywhere. Otherwise the observer isn't effectively suffering from the Blinded condition, so the foliage in that area must not be sufficiently dense to qualify as Heavy Obscurement.
Yes, going back to the trees behind my house, even though the leaves and branches are close together enough in many places to obscure the presence of a person among the cluster of trees, there are also gaps large enough that I can see the shape and color of the house behind quite clearly.
Only the places dense enough to obscure the person would count as Heavily Obscured. The gaps are not Heavily Obscured, as a creature standing in such a gap would be visible to you.
There's no contradiction. I really can't see anything in that area. There could be someone up in that tree looking at me, and I would have no idea. Nevertheless, I can see telephone wires traversing the area behind the tree and the sky peeking through the canopy behind that.
If someone was in that area and intersected your view of the telephone wires, you would see them, yes? By definition? You can see the wires, so you'd definitely be able to see something in front of the wires. But anything you can see you aren't effectively Blinded towards, so you're not effectively Blinded with respect to everything in that area. So how can the area be said to be Heavily Obscured?
Maybe a good way of putting it is this: if you drop a stone monolith (shorter than the trees) at a random place in your clump of trees, are you, as an observer guaranteed to be unable to see the monolith? If yes, cool, then the area is Heavily Obscured--you are effectively suffering from the Blinded condition with respect to everything in the area. If instead you might see the monolith, then the area must not be Heavily Obscured because you aren't effectively suffering from the Blinded condition with respect to everything in the area.
So yes, it definitely sounds like we are treating different levels of foliage as sufficient to qualify as Heavy Obscurement. I think the rules for the Blinded condition require full opacity, and you do not.

As far as I can tell, the other posters have only suggested that feel like their interpretation allows them to explain the inconsistencies in RAW for their own benefit. They were told that they were wrong to do so, and that their interpretation was inconceivable, and they've felt the need to defend it. Not to tell others that they are the only ones doing it correctly. I really don't think I'm wrong about that. They were defending their right to exist as an alternative viewpoint to the clearly much-more popular (but IMO equally problematic) Ink-Blot Darkness. In doing so, they may have tried to explain why THEY think it's "better", but that's not the same thing as "you have to do it this way too".

How about we agree to disagree as to the viewpoints of other posters expressed in past posts? The alternative is wading through 40 pages to find quotes, then arguing about the context of those quotes, and we'll likely just end up conceding that the other one's interpretation of the thread is plausible, even though we each prefer our own.
It sounds like you are saying that if a solid object should be backlit, but isn't due to Darkness making everyone blind to everything inside of it, that the object is transparent if you can still see things behind it.
That's a possible interpretation, but so is "magic." "Magic" seems like a cop out in this circumstance, so I think that making Darkness pitch black and allowing no light to go through it is the more elegant solution. No seeing anything behind an area of the Darkness spell.
Use small "d" "darkness" (I'm talking about natural darkness in general) and you're pretty close.
And magic can explain a physical impossibility, but just using "magic" as an explanation doesn't tell us what an observer sees. Somehow the DM has to describe to the player what the scene looks like to the character, and the text in the book definitely doesn't have any rules to that effect. So even if a DM hand-waves away any inconsistency, they still need to use their own judgement on the visual result.

An observer only suffers from Blinded "when trying to see something in that area", so as long as there are sufficient places for things to not be seen, it works.
Only the places dense enough to obscure the person would count as Heavily Obscured. The gaps are not Heavily Obscured, as a creature standing in such a gap would be visible to you.
I'm describing a real scene. The rules are abstract. No area of vegetation is as uniform as you are describing, nor does it need to be imagined that way.
If someone was in that area and intersected your view of the telephone wires, you would see them, yes? By definition? You can see the wires, so you'd definitely be able to see something in front of the wires. But anything you can see you aren't effectively Blinded towards, so you're not effectively Blinded with respect to everything in that area. So how can the area be said to be Heavily Obscured?
Yes, if someone put their face in one of the gaps in the canopy, I could see it, but that's not where someone would be to not be seen. I don't think there's anything there to support someone's weight. They would be where the leaves are more dense, closer to the center of the tree. Again, you don't need to effectively have Blinded with respect to everything in the area, just things you're trying to see.
Maybe a good way of putting it is this: if you drop a stone monolith (shorter than the trees) at a random place in your clump of trees, are you, as an observer guaranteed to be unable to see the monolith? If yes, cool, then the area is Heavily Obscured--you are effectively suffering from the Blinded condition with respect to everything in the area. If instead you might see the monolith, then the area must not be Heavily Obscured because you aren't effectively suffering from the Blinded condition with respect to everything in the area.
No, that isn't how I think about it. I would say that in an area of moderate foliage, there would be pretty much no opportunity for a 15' monolith to escape notice, while in dense foliage there would be ample opportunity for it to be unseen.
So yes, it definitely sounds like we are treating different levels of foliage as sufficient to qualify as Heavy Obscurement. I think the rules for the Blinded condition require full opacity, and you do not.

I can't think of the last time I've seen a silhouette in real life
I mean photo's where they can play with contrast and lighting sure, or photo's where they set up their camera to be at the perfect angle during a sunset to capture it, but in general - the phenomenon seems pretty rare.
