Won't end rendering....

[anthony_kyriazis]

Hello,
i have a scene with a lot of instances of folliage, and the scene renders and this is the output of the vray log, but at the end it donesn't stop rendering, ie the gpu stops rendering but vray/houdini doesn't show that its finished. Thus i cannot render out the animation... it just gets stuck.

any ideas? thanks

ok so basically, it takes about 25 minutes to save the exr AFTER it has finished rendering... any ideas why? ( i am on 2 nvme ssd drives in raid 0, so speed and space are not the issue)

That seems very unusual for such a small image. Seems like something is wrong. Can you send a scene to chaos?
have you tried rendering on another computer?
