Is it possible to clamp a texture sample to the texture itself and not as a filter?

[anonymous_user_adc3f730]

You can’t do that, but since textures can’t store negative values anyway

Is that also true for render targets because that’s not what is happening in my project.

Why not just put a clamp node after the texture sample when you read from it?

I explained that in the second part of my post:

The reason i can’t just use the Clamp node within the material editor is because that acts as a “post process” (it’s a filter) and i need it to be “real” and actually edit the
RT itself so that each Texel is never below 0.

that’s just going to draw -0.1f directly, it won’t subtract anything from the existing value

I have a additive emissive material that contains a value of -0.1f and when adding it the the existing texture it does subtract -0.1f
