Hi!

As far as I can tell, the specular material uses float IOR value. I want to create a material that's IOR is changing according to a mask distribution. (black is 1.0 white is 1.2 lets say)
I tried to connect a texture, I tried a mix material where the texture is mixing two fix values (values above 1). But I think it is just not working.

I also tried to create an OSl texture node, with output type float, but it is not allowed.

Any solutions?

I'm afraid that this input is not texturable. That means that you can't link a texture node to it, including probably an OSL texture. It only accepts a constant float value.

Thanks,
