VRayscene fast playback

[RichardBlank]

We have a tennis arena that we converted to a vray scene, but the play back is really slow. I understand that the scene can be slow if the VRayscene is animated, but if the Vrayscene is static it would be nice to have faster playback.

Yes, this is something that we can definitely improve. It would help if you can provide us with a test case.

Best regards,

Ok, here is a test scene. https://we.tl/dRg8fqSSGc

@RichardBlank, when you've pressed "Cache Animation" button node was switched to the mode in which it was loading data from file on frame change (if frame is not already in cache).
You could set VRayScene node "previewCacheType" attribute to 0 (zero) to switch it to single frame mode, like this:

setAttr VRayScene_Wimbledon_Daylight_03.previewCacheType 0;

Additionally remove time1 node connection from VRayScene node.
This will load only one frame and will not recompute mesh data on frame change.
Anyway I'll think of a better animation loading approach.
