If you have XRef Object nodes and apply ProOptimizer to them and Forest is using them as custom objects, Max will crash whenever you try to load that scene in the future. I discovered this while working on a project. I had assumed it was some scripted tools I was testing, but it turns out to be Forest using XRef Objects that have ProOptimizer. I used ProOptimizer because I can't collapse the objects and because I wanted to fairly accurately preview the forest distribution and Point Cloud display mode wasn't good enough for my needs.
When you have this bug, you cannot open the Max scene because it will just crash to CER.
There is a way to open it to fix:
- Type this into the MAXScript Listener and hit enter on each line:
- DisableRefMsgs()
- DisableSceneRedraw()
- The Click File... Open and open your scene
- Type this into the MAXScript Listener and hit enter on each line:
- enableRefMsgs()
- enableSceneRedraw()
Now you can remove the ProOptimizer or collapse the objects as needed.
Hopefully the bug can be fixed.
