Adobe Standard Material and IRAY?

Hello Patrick,

The Iray implementation of the Adobe Standard Material does not use the ambient occlusion map by design.

Please note the ambient occlusion natively computed by Iray's path tracer is physically accurate, and should not require an additional texture. In that sense, the Adobe Standard Material shader is 'correct' in ignoring the ambient occlusion texture. That being said, we agree it is confusing that there is an available slot for a texture which ends up being ignored.

We will add an Intensity parameter to the Ambient occlusion group for the Adobe Standard Material shader in Iray. This parameter will control how much of the ambient occlusion texture should be added to the ambient occlusion computed by the Iray renderer. The default value for this parameter will be 0, which will make it clearer why the texture is 'ignored' by default as well as provide more control to the user.

Best regards.
