Vray Volume Grid - CPU Usage remains high after rendering locally

[jpl1040]

I have noticed an issue with the VrayVolumeGrid where the CPU usage remains high after rendering completes.

I've attached a few examples.

1 Grid before rendering CPU usage around 4% average
1 Grid after rendering CPU usage stays around 11% average
3 Grids before rendering CPU usage around 4% average
3 Grids after rendering CPU usage stays around 28% average

The CPU will remain high until the scene is reset, max is closed, or the vrayvolumegrids are deleted and a garbage collection is run.

I made a similar post about this in the phoenix forums regarding the same issue with phoenix grids, and the problem was quickly identified and fixed in a new phoenix nightly build. I believe it was related to the fact that this is a multi core machine, if that is helpful at all.

Please advise.

Thanks.

I'm a bit confused why do you open the same topic in 3dsMax forums as well.
Would you like to notify other users or something else?

The case has been fixed like you already mentioned, and it is definitely much better to continue the conversation in the original thread instead of going to a completely new place where all the people involved with the case are missing.
