V-Ray 6 Render Stop automatically

V-Ray V-Ray for 3ds Max General
1

Hello again Chaos team,

I’ve tried V-Ray 6 recently, some features is really amazing, I appreciate your hard work, but I still met some bugs.
Render will Stop automatically after finished 2-5 frames while I was rendering multiple frames without any error or warning show in log. It always stop after finished random frame, sometimes after 2 frames, and it keep rendering 8 frames once, and then it stop. I guess it might because of the Scatter which I made some value animation like density and random rotation, when the Scatter shows in my scene and this bug will happen, but I can not 100% sure.

By the way, the value animation of Scatter also can’t show in Max’s preview. Like I want my seed increase gradually then I animated density value, but in Max preview Scatter looks like freeze.

I recorded my screen and upload my scene, maybe it can help you figure out what is happening.

Screen Recording:
V-Ray 6 Render stop at about 0:45 - YouTube

Oh I just found the V-Ray 6 Beta section of forum but I don’t know how to change my post or delete it, is it OK to post in here?

Hello,

Do you use any third party plugins - maybe tyFlow ? They are not updated for V-Ray 6 and are expected not to work properly.

Best regards,
Yavor

Hi Yavor,

I do use tyflow, I will check it for more.

Thanks for reply

But did you remove all tyFlow objects ?

I uninstalled tyFlow just now and there are only V-Ray and Phoenix for V-Ray6 but I didn’t use phx, it keep happening.

Hi @yi_xiang ,

We managed to reproduce the issue and it is, as you suspected, related to Scatter. Seems quite random - it sometimes renders the whole sequence, and sometimes stops after a random rendered frame.
Logged as VMAX-12246 so our devs could have a look. We’ll let you know once we have more info - and thanks for the pointer!

Hi Nikoleta,

I’ve tried the newest version and I think the problem is solved, nice job!

I have exactly same issue right now in max 2024 with forest pack and tyflow (everything latest version). Do you know about any fixes or if its even known issue?

By turning off things and rerender the culprit turned out to be “VrayProxy” once I turn them off it renders fine. I have quixel’s high poly meshes as proxys there. Vray latest nightly build also installed to check if the bug persists, and it is in nightly as well

It would be best if you could send the problem scene to our support.

Im not sure that I can, its also more than 5gb only for max file

Update: in 2023 it renders without any problems

Scene Size doesn’t matter for us, we have the room to store it.
If you could send one over, it’d help.
