Yep. The way I picture it is to imagine taking a picture of a room illuminated by a single bulb, and then photoshopping out the bulb. You can't see the bulb, but you can still work out which part of the room is most brightly lit, and which direction the shadows are pointing, which will let you guess where the bulb would have been in the original image. At least, you can if there's only one light source present.On the question of a torch held by a creature that casts greatest invisibility or invisibility, the torch becomes invisible.
However nothing is blocking the light from the torch. Invisibility doesn’t do that. So the light from the torch still works and lights up the area around it. You just cant see the torch.
