It uses the player's position to set an amount of lighting and reflections on the model (try not to use some textures ended up with "_vertex" because you will see them behaving weird in game due to how this specific shader is managed) This is a shader to render model's textures. You've surely seen another shader called VertexlitGeneric. Lightmaps are static, meaning that the lighting stored for each of these surfaces won't ever change in game anyways, these surfaces can still cast more lighting or shadows coming from an env_projectedtexture, which has dynamic values that can change in game. VRAD does that for each of your map's surfaces textured with a Lightmappedgeneric texture. When the compile (VRAD) finds this shader, it gathers the lighting surrounding each surface textured with your texture and it stores this information into a lightmap (thus the name of the shader "Lightmappedgeneric") which is fixed to that surface. This is the one you'll use for almost all the textures in your map. The most commonly used shader is the Lightmappedgeneric. You then need to open a bracket for a block of code, then put all the parameters you want to control and set up, and then use another bracket to close the block. This is declared at the very beginning of your. VMT is the shader you'll want the engine to use to render your texture.
Take a quick look to these 2 examples first:įirst thing you want to set up into your. Well, you have some information on the wiki, however, I'll try to tell you some basic knowledge so that you can have a first overview. Also I could use some help learning a few command lines for vmt files, again I know a few but I am limited to those few atm.
