V-Ray 3.50.03 - VrayIES crashes RT

[labulle]

I've been used to adjust my VrayIES lights positions in 3.40.03 in ActiveShade mode with V-Ray RT (CUDA). However whenever I try to render with RT after the 3.50.03 update, it hangs with this error :
error: [VRayRTMax::renderThreadProc] Exception occured in rendering thread.

Same problem with a blank new scene (3ds max 2016) with a single VrayIES, and VrayRT with default settings (not even CUDA, but CPU).
VrayLight is fine.

Hello,

I reproduced it here - thanks for the report and sorry for the bug. We'll probably release a fix about that soon.

Best regards,
Yavor

Thanks for your quick response ! Can't wait for the fix, it's the only annoyance for me within the 3.5 awesomeness
