# Bugfix: to avoid playblast generation issues with sequence image plane,
# cached playblack need to be enabled
# Firstly, save and switch the anim evaluation mode to parallel
# (needed for the cached playback option)
prev_evaluation_mode_info = cmds.evaluationManager(query=True, mode=True)
# Switch to parallel
cmds.evaluationManager(mode="parallel")
# Then, save the current cachedPlayback value to be able to apply it again after playblast capture
