We have project that is migrating from Houdini 19.0 to 20.0
In Houdini 20 way albedo pass is being rendered had changed. In change log found this:

20.0.548:Matches Albedo AOV between Karma CPU and XPU. The Albedo AOV now shows total albedo and not just diffuse albedo.

Is there way to get only diffuse albedo now? Looked up LPE expressions, but didn't figure out how to get albedo via LPE.
Thanks!

Here's image showing problem:

Bumping this, having same issue, as I noticed specular and fresnel are contaminating the albedo built in aov.
Any idea how to get a diffuse only albedo beside making a custom shader aov and passing through it for every diffuse input which is really cumbersome ?

thanks

Seems like a bug, considering that the name of the exported channel is "export_basecolor", it shouldn't be anything other than the value connected to the basecolor input.

A cursory test also shows that the AOV does not match XPU, if metallic is not zero. If your ticket was closed, I would try to reopen it.
