Siz said: I don't see the point in making the door thicker, all you'd be doing
is make the separation between one room and another larger, which you
can do with two doors, but I don't see the reason for doing so. If you
can't see through it, the thickness doesn't matter. I actually
don't know if Dynamic Lighting wall thickness matters, I thought it was
just a visual help for the DM to target said walls. If it has a visual
impact then it makes sense that the doors should have the same
properties. Actually in my case, I want to make the doors thinner to match the thin walls I use. As you figured, wall thickness has an actual affect on what players see. The thinner the wall you use, the more details are available for the player to see things such as doors, windows, or even knowing what kind of wall you are using (say you want an impression of cobblestone versus wood versus cave, etc.) But the door is only a constant thickness, and would either make a bulge in a thinner wall, or the inverse on a thicker wall. This I can begrudgingly accept for normal doors, but secret doors make it hard, as it can spoil the presence of a secret door for perceptive players unless all walls use the normal thickness. So, thickness does matter, especially if the wall is between two rooms. My next post has an example.
