Howdie.

I am not able to figure out how to get a good Multiply texture. I have a chrome like surface, and I have a dirt texture I want to overlay over it. If I use Photoshop, white areas would be invisible for the overlay, and darker shades of gray would multiply with the layer beneath. But when I try this in Octane, it looks like the white in the overlay shows up in the render as a cloudy diffuse layer. So the chrome gets washed out. What am I doing wrong?

I had a demo of something like this in my Octane Tuts but had completely forgotten about it. But it only allows for multiplying TEXTURES, not materials. And I do not see how to multiply an image TEXTURE over a background MATERIAL.

hi treddie,
you could add your texture in roughness or specular map and adjust it through gamma value.
