Eh, the scene is crashing on start-up - I can't even open the scene to archive it; the scene references assets on the local disk that might be relevant.
I'm still in the process of diagnosing the scene, but so far it looks like passing different elements in a mat graph into different parameters of the Ornatrix groom is precipitating the crashing behavior.
For example, bitmap -> color correct -> distance map; each node goes into a different parameter of the Ornatrix groom.
one parameter might be adjusted by the bitmap -> [color correct]
another parameter might be adjusted by the [bitmap] only
another parameter might be adjusted by the bitmap -> color correct -> [distance map]
If it's helpful I can just send the scene file, but there will be a ton of missing external assets, e.g. bitmaps, HDRI, etc.
