Bug (potential): Flickering tyBoolean

[CLF73]

Hi there
The GPU engine combined with camera motion blur, causes the tyBoolean modifier to act up and flicker randomly on our render nodes.
See video for example.

I feel pretty confident that this isn't a problem in the CPU engine, as when I raised the issue on the tyFlow FB page, Ibele didn't seem aware of this issue and he started contemplating the Boolean routine instead of a possible render issue.
Note: All render nodes have the exact same software, and its random which machines causes the flicker, from render session to render session.


I have a strong feeling that this can be related to camera motion blur, in combination with the GPU engine.

This is my Max setup


The TyFlow used is not updated to the latest build, but this has been an issue since we started using the GPU engine more than a year ago, with several tyFlow builds. So please feel free to test it in your most recent tyFlow build, as I think the result will be the same.

Which render manager are you using? Does it happen when rendering locally? Which V-Ray version do you have installed?

[CLF73]

No It doesn't happen locally. (only when submitted to render nodes via Deadline - Deadline Client Version: 10.1.19.4 Release / FranticX Client Version: 2.4.0.0 Release)

I have just rendered this local test -

These are the requested specs.

Hi CLF73

We rendered your scene file here using Deadline 10.1.15.2,3dsmax 2021 and V-Ray 5 update 2.1. There is no flickering as in your first video.
Please see our render here.

If it's possible to arrange a remote session, we can troubleshoot on your machine. Could you please contact us using the contact form here and mention this thread.
Thanks!
