Here's an example from the HL2 code of making a material from code: KeyValues *pVMTKeyValues = new KeyValues( "UnlitGeneric" ); pVMTKeyValues->SetInt( "$flat", 1 ); pVMTKeyValues->SetFloat( "$vertexcolor", 0.05f ); IMaterial *pDrawFlatMaterial = materials->CreateMaterial( "___flat.vmt", pVMTKeyValues );
