Hi there,

Well I am in an lookdev stage currently. And the production wants to use XPU and CPU for this show. Just noticed that the output of XPU and CPU renderer is quiet different. Now I try to sort out what is causing that. I know they are different renderes...

Now I ende up with an clean scene with just on grid and no textures. It seems that roughness value of 1 showes up diffrently. I am also not sure about the Normals... Its supposed to be a MaterialX project! but the princeple is also producing differences in roughness.

would be glad about any kind of informations regarding this.


thanks guys!

They are slightly different in how they conserve energy when combining Fresnel blended layers. The roughness is the same, but how they are scaled at glancing angles can be different.
