<remark>
|
||||
Consider using built-in functions such as <funclink>SetGamma</funclink>, <funclink>SetMatAdjust</funclink>, or <funclink>SetClrModulation</funclink> for changing colors instead of writing a custom shader.

<code>AddFragmentShader("Landscape", "slice(color+1) { fragColor.r = 1.f; }");</code>
