GPU Cache not loaded when playblasting

[e_reynaud3XF2J]

Hello,

I'm working with a script in Maya, and I've encountered an issue when dealing with scenes containing GPU caches. These GPU caches can take some time to load, and when I try to playblast the scene, the GPU cache geometries don't appear in the playblast until they're fully loaded. Is there a way to set up a callback or a mechanism to detect when all GPU cache geometries are fully loaded (not just their bounding boxes) so that I can initiate the playblast only after they're loaded? Any guidance on how to achieve this in Maya would be greatly appreciated

import maya.standalone
maya.standalone.initialize()
import maya.cmds as cmds
myscene = "myfolder/file.ma"
file_output = "myfolder/out.avi"
cmds.file(myscene , open=True)
cmds.playblast(filename=file_output)

Not an expert in this area but you should be able to change the gpuCache preferences for background reading in your script before loading the file?

cmds.optionVar(iv=('gpuCacheAllAuto', 0))
cmds.optionVar(iv=('gpuCacheBackgroundReadingAuto', 0))
cmds.optionVar(iv=('gpuCacheBackgroundReading', 0))
cmds.gpuCache(edit=True, refreshSettings=True)

Thank you very very much!

It worked.

When I try to call cmds.gpuCache I'm getting the error:

AttributeError: module 'maya.cmds' has no attribute 'gpuCache'

This is in Maya 2023.2. Is the cpuCache command only available in interactive mode? In batch mode the command should be available but simply do nothing.
