| SHADERINFO_0 | None. |
| SHADERINFO_TRANSFORM | Channel needs back-transformed data. (Required for back_p.) |
| SHADERINFO_BUMP_SUPPORT | Channel shader supports the new bump system. This is strongly recommended for all shaders but simple 2D (UV) samplers. |
| SHADERINFO_ALPHA_SUPPORT | Channel shader supports alpha output. |
| SHADERINFO_REFLECTIONS | Channel shader computes reflections. |
| SHADERINFO_DUDVREQUIRED | Channel shader needs du/dv bump mapping data. |
| SHADERINFO_DYNAMICSUBSHADERS | Channel shader has a dynamic list of subshaders in its description. |
