Closing the maya session and reopening causes issues #9

Closed aluminal closed 8 months ago

aluminal commented 8 months ago

Hello! I am able to import the facial animation from unreal to maya perfectly using this script. The issue I'm seeing is that if I save that file or save as in a new location, close the current maya session and reopen; there are some problems. If I select a metahuman control and try to set the current metahuman I now get an error "Missing critical node, embeddedNodeRL4, used for rig logic!". Also as I scrub through the timeline, the facial controls move, but have no influence on the mesh. Just wanted to check if you are seeing this behavior. I can also provide more detailed repo steps if necessary. Thank you for providing this script and updating it, it's honestly quite amazing.

Hi, I've not experienced this. Possibly the DNA file path is invalid or missing?

In your python script editor, to find the node, run this and it should select the node

import pymel.core as pm
embedded_node = pm.ls(type=pm.nt.EmbeddedNodeRL4)
pm.select(embedded_node, r=True)

In the attribute editor, make sure it points to the correct DNA path. Btw, if you move this file, it won't update in the maya scene.

Thank you! It was definitely an issue with the DNA path. I was able to fix the issue by first opening maya and then opening the maya scene; instead of double clicking to open the file directly. Thanks for the tip and thanks again for all your work on this script!
