i found a model below

when i change use command tool button [Convert model to segmentation node]

i convert the model to segment,it’s well displayed with both model and segmentations
then i save the scene as .mrb file
when i reload the .mrb file , the model displayed well , but the segmentations can’t display,the data seems empty
both model and segmentation can’t display on slice panel

the version 4.11 and 5.02 both has the problem

If I understand well, based on your description, this is not an issue with conversion but with save/load. Please confirm that converting model to segmentation works. Can you reproduce it with data available in Slicer? (For example doing a very simple segmentation on a sample volume, convert it to model and then back)

the origin operate on slicer is fine.
