TyFlow motionblur issues

[im.thatoneguy]

I'm facing a lot of motion blur issues in Tyflow with Vray 7 max 2025. Reverting to Vray 6 seems to restore motion blur. Problems arise with sub-frame integration of simulations particularly. But it's super random with errors of "changing topology".

Thanks for the report. I've logged it (internal bug-tracker id: VMAX-14684). It is indeed something with the subframes since setting the "Time step" in the tyFlow sim resolves the issue.

The devs told me that Tyson handles everything on the CPU. We only do it in GPU, where the issue is not present. Could you message him with the report or would you like me to do it?

We've got a Tyflow ticket opened as well. I'll add a link and VMAX report ID to it.

Thanks
