Hi, I just saw this..

20.5.418
Added 'A' (albedo) event type

Does this mean I could export an albedo for rhe spec, roughness etc?

Best. Mark

Hi. Roughness map does not (or should not) affect albedo of a given BSDF so it can't be used for that - for that you still have to use a shader export (via Karma AOV VOP).
The built-in albedo AOV outputs total/combined albedo and there were a number of users asking for a way to filter out glossy/specular component as they were only interested in diffuse. This new feature allows for precisely that. For example for diffuse reflection+transmission albedo, you can use the following expression: 'CDA'

Hi. Thanks Dlee!
