Vertex Maps Slowing Down Viewport
-
I already just posted one question, regarding the creation and modification of vertex maps.
However, I'm finding that regardless of that, I'm still encountering extreme viewport performance degradation, directly related to my objects' vertex maps.So...is there any way to optimize such maps, or more realistically, a way to only have them active at render-time?
I'm only using them for material creations; not for deformations, nor other FX. So, they only need to be active when RS needs to render a frame.Does this question even make any sense?
Thanks.

Hi entry-newspaper,
Depending on your object's mesh resolution, there can be a lot of data that needs to be processed.
I copied this text from the other reply:
Perhaps the Freeze can store those better if they don't change. In the moment they are stored, the selections can be switched off.
You can check the specific processing time in the
Main Menu> Window> Object Profiler.I try typically not to guess here, but I'm sure my little system here will behave differently than yours, so any file exchange might result in something that will not help. I know asking questions might waste time on your end, but let me try:
Have you tried to bake those as Alembic files?Perhaps create an RS Proxy from it
If the draw on the system is very heavy, perhaps explore XRef and the use of a Proxy.
Enjoy your weekend

Hi, Dr. Sassi.
Thanks for the suggestions / questions.
Unfortunately, I really can't get around the direct use of the "live" vertex maps, on the active objects. There is simply far too much direct control over the RS materials, to do anything else.
Over the weekend, I tested different ways to actually construct those vertex maps; some using freeze objects, others, directly linked to the polygon tags, etc.
Ultimately, no real difference in performance. Interestingly, the performance hit comes when the actual objects (with the vertex tags) are animated. When those are static, and only the camera moves, it's as fast as can be.
So, clearly, there is something "under the hood" with the way Cinema processes vertex maps, when motion is involved. -
Thanks for the reply, entry-newspaper.
I would suggest to check with tech support.

Good idea. While, it doesn't necessarily present itself as a bug, perhaps it's an efficiency aspect which could be improved, in the future.

Thank you for being open to this, entry-newspaper.
I understand Tech-Support is supported with tech; it is not limited to bug support. We all want things to work smoothly. I never considered it as an isolated single question/answer. If there is something to improve or fix, it is to the advantage of many.
Fingers crossed, there is some improvement afterward.
All the best
My best wishes
