3.5 IPR: Scenes with Displacement refresh after scene change

[kosso_olli]

Hey,
I have a scene here with some displacement on a parking deck. As soon as I move a light around or something, the IPR refreshes and compiles geometry, instances etc. Because of the displacement, this takes very long. Does the IPR really need to evaluate the displacement on every change to the scene?

Any hints regarding the issue? Do you need a scene?

Thanks for the report. I'll let our developers know about this and we'll get back to you.

A scene will be very helpful if you can send it to vlado@chaosgroup.com

Best regards,

Thanks for the scene; for the 3.50.04 patch, we have tried to make displacement generation faster, but we also have a general fix lined up for this. It will take a while to implement it as we need to transfer some geometry update code from V-Ray RT to the production V-Ray. Will let you know when it is in the nightly builds.

Best regards,
Vlado
