Has any been able to find some sort of workaround to get Cryptomatte working in Solaris? Also does anyone know if this is a high priority item on the development list? This essentially makes or breaks whether Arnold is feasible in Solaris for production for us.
Support for imagers and cryptomatte depends on adding support for arbitrary node graphs. Some of that work was already done in https://github.com/Autodesk/arnold-usd/issues/964
AOV shaders (another requirement for cryptomatte) is a high-priority ticket:
https://github.com/Autodesk/arnold-usd/issues/661
Is this something we can look forward to in an update in the coming months or is this a much more challenging issue.
