Issue of hollow shell while creating cardiac segmentation

Hi Andras,

I tried using probe model module but i am not sure what information i am getting to use to color different parts of one segment. I am attaching screenshot of what i got from that module and when i used it in models module.

Also, while looking for some discussion in slicer forum for the same, I caame across this thread" coloring in VR view"-The solution given is confusing and not very clear. https://discourse.slicer.org/t/colorize-model-for-vr/6299.
Would appreciate further directions.

Thanks,
Sarv
