If i have a texture which is a roughness map but I need to plug it into the gloss input for Corona, I need to invert it so I use the tonemap shader.
However, the tone map shader invert button doesn't appear to work correctly and instead puts the gloss to almost 100% gloss/ignores the map altogether
If I use the colour ramp and switch the white and black input (to invert the texture) it works correctly.
If I use the tone map shader invert button. its wrong
If i set the gloss to 100%, it looks exactly the same as setting the tone map shader to invert.
So its almost as if the invert button just completely makes it ignore the texture altogether?
