Waves in sim changing details, randomly

Hi,
I have issue with sim, it looks like it changing level of details randomly, here is a link to short animation where you can see problem https://drive.google.com/file/d/1c4nlMdygFURws9QeaeGyBJpJ-DLa0CKA/view?usp=sharing
Also here is two frames where one frame goes after another.
Simulated with Phoenix 4.40.00, Build ID: 20210407 for 3ds Max 2019 from Apr 7 2021
thank you.


Hey,

Looks like you have motion blur enabled, but the grid is missing the veloctiy grid channel. By default Phoenix bakes all the needed channels for a Restore every 15 frames so that you can restore from these points.
This way every 15th frame will be propely motion blurred while the others won’t. If you enable the Velocity channels in the Output rollout and sim again it should render correctly.

Cheers!

Thank you for your quick reply,
I will enable velocity channels and sim again, hopefully it will fix the problem.
Thank you.
