Velocity render pass for volume

[dimitri_allonneau]

Hello,

I wanted to know if it's possible to render a separate velocity pass for volume because it's quite unstable to render motion blur directly inside the render (with vel.* or vel inside the VolumeGridShader)?

Thank you!

Hey dimitri_allonneau ,

Yes, it's possible. To get a velocity AOV, add it in the Render Elements list and enable "Volumetric Geometry" under the Rendering tab of the Volume Shader. I've attached an example here --> LINK.

// if possible, could you send us a scene to check for the issues you've mentioned you are having with vel.* and vel fields?



Hope that helps!

Okay, I tried but it seems not working for the velocity AOV. I've attached the scene

Thank you for the help!
