NEW DR Issue - Max SP3 and Vray 2.5 nightly

[Morne]

Hi Team

So after the initial excitement of having a fix for the Max SP3 issue, that went away when we started having a NEW DR issue. Intermittently we are suddenly getting darker buckets. Only way to fix it is to restart the workstation and all the slaves. We will have 4 or 5 normal renders, then it starts all over again.

I've narrowed it down to IR Map and the GI element also shows this. When rendering with LC/LC or BF/LC, it renders fine. Just the IRmap is resulting in this weird issue. There's nothing wrong with the scene as it is starting to do it on all scenes. It started after installing SP3 again, and the VRay 2 nightly that was suppose to fix the SP3 issue. At this same time, we also started running Spawner as a different user to overcome the projects folder not resetting after a render issue.

The nightly we use is:
"vray_adv_25501_max2015_x64.exe"

Hi Morne,

I'm running a test right now to see if I can reproduce the problem.

It will be better to send us a scene for this issue. I can't reproduce it with my test scene.
Do you use the option "Restart slaves on render end" in your setup ?
Do you render single frames (different camera views) without precalculated Irr. maps ?

One of the guys stopped having it after restarting the slaves and workstation. We have "restart slave on end" ticked and for stills we dont use precalced GI

We're doing some more tests. Will let you know what we find
