Hello Master.
I have a scene created with version 0.4 of Node..
Is there a way to replace all 0.4 Nodes with the new 0.5???
Hello! Unfortunately, there isn't an automated way to do this. You will need to manually replace each node with the SSRT 0.5 node group.
If you feel confident with Blender's nodes at all and can match names to names. You could directly update the node group instead. only having to do it once. That's what I did with a scene I updated dozens of materials to SSRT in
