Maya: Load VDB to Arnold keeps velocity FPS on 24.0

[BigRoy]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior:

When loading a VDB cache that is created in a 25 FPS project and loaded into a 25 FPS file the loaded aiVolume via pipeline remains at the default "velocity scale" of 24.0

Not entirely sure if that as erroneous effects but it seems confusing at least. According to the Arnold docs:

Velocity FPS
Factor which divides the velocity channel values in order to convert from (assumed) units of distance per second to units of distance per frame, as required for shutter times in frame units.

Expected Behavior:

It should match the FPS of the loaded file, and otherwise fall back to the FPS of current task if publish doesn't have any fps data.

The attribute is called velocityFps so it should be along the lines of:

cmds.setAttr(f"{aivolume_shape}.velocityFps", fps)

Version

1.0.0

What platform you are running on?

Steps To Reproduce:

1. Load a 25 FPS vdbcache into a 25 FPS project.
