GPU mode - dir light options diffuse and specular can't be disabled

[Micha]

See screenshot - both options disabled, but the effects are still there.

PS: I can't edit it - the topic name should show "can't".

Hello, Micha,
Thank you for reporting this. It is a limitation of the GPU engine.
I have inquired my colleagues of its current state and priority. Will post an update once they have reached a decision.

Kind regards,
Peter

A ticket to support disabling these parameters in V-Ray GPU is now logged.

Would like to clarify that the "Affect diffuse" and "Affect specular" controls for direct lights have not been intended to be supported in V-Ray GPU. In this case, the UI incorrectly displays controls that currently have no use.

Kind regards,
Peter

Oh, that's hard. So, it will not implemented in the near future? Often I used direct lights to bring light to dark areas and often I disabled speculars. Or I use specular only lights to add some reflection effects. It's a big step backward to loose this controls. Or do say it's not implemented now and it will come later?

The request is already scheduled and has also been discussed with our internal 3D artists team for further feedback. We hope to see it done soon, however, I cannot currently provide an ETA yet.
