Max velocity doesn't work

“Max velocity in last frame” in Velocity render element doesn’t work. it is always 0. It only works on V-Ray CPU. Does it not support GPUs?

I use 3ds max 2025.3 / VRay 6.20.07

It’s not supported yet. It is logged (internal bug-tracker id: VGPU-3334), though.

OK. I decided to use Native EXR, so I no longer need it.

Thank you.
