The Trinity Rendering Engine is made by Andrew Lucas, which contains a lot more features, which are even included in Valve's powerful "Source" Engine. Trinity Render is now being wisely used in most of the mods.
Version 1.0 of Trinity Render: Custom Edition. It contains source code and .fgd file or mapping. FGD contains new entities which use more of trinity's features.
Too bad I don't know how to use the SDK.....
It gives me errors about me missing "gfx/env/watershader.tga" Where do i get it?
