I wasn't posting in this thread because I was busy implementing the things I was modelling.
so far I have ingame
1 wall
3 wall decorations which allow for 4 practical combinations
1 ceiling
1 floor
For reference, I got invisible pillars to work. And it was correctly stated previously, you just make a blank .dds saved in DXT3 format (explicit alpha) so the alpha isn't made white, and you must set "alphatest" to true. See here in materials.lua:
Okay! This worked for me, but I'm tweaking the settings right now. It appears that classes aren't altogether that determinitive of what functions they can have, which leads me to believe there are a number of hybrid things you can do.
This worked for me, but I am still tweaking the exact settings. It creates, in effect a decoration that is also a lightsource that doesn't replace wall.
Oh yeah, and what is a [models] thread without models?
here is what I currently have implemented, the spike and the socket are seperate decorations, I only realized after compiling the dungeon I should have shown them off seperately. Textures are piss poor, but so long as the models work correctly I'm happy.
Image might be a bit large, so spoilered, but less than 1mb. Also some of the image is cut off, so you can save as to see the right side.
