Grimrock

I'm looking through the original Grimrock textures and I see some of the files have shadtex in their names. It only crops up on objects like the green slime and red gem, healing crystal and ice shards.
And yet- I don't understand how the models are referencing these images because it's not included in the material definition.

Been wondering this too because I've tried to make new gems with different colors but the nice swirly effect is lost when you change the dif texture.

They use a custom shader. The shadertex.tga acts kind of like an environment map that rotates.

But how does the object reference it without being in the material definition?

The only material that lists it anywhere is the red_gem

Currently it's just hardcoded instead of being supported with the material system so it's not moddable. Back then we didn't know we were going to add modding support so we took a lot of shortcuts like these.

I like that word "currently"
Thanks for unfogging that little mystery guys. :3

Allow us write our own shaders. Its a good idea, honest!

Simply having access to shader textures may be enough ...
