Basically I need to apply the shader to everything that the...

    Unclamped RGB in shaders? Possible?

    GM2 clamps rgb values (0-1) in shaders.. Is there any way to unclamp them? Because when I implement shaders from other sources like shadertoy I realized they are not clamping rgb values and rgb values can get - and + float. Yes I can normalize in a range them with very high precision floats...
