Hello，everyone！  
I have a problem using the PRISM Rendering in the software version 2022-02-05, as shown in the following figure

 ![2022-02-05](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/3/d/3d8e8e4b081b3801a44f10866dbb2ac5ab6e7109.jpeg)  
I operate according to the sequence in the figure. When initializing the center, the volume rendering ROI in the fifth place in the figure appears instead of the endpoints of the previous version

What can I do to achieve the following results

I hope someone can help me. Thank you very much！

Yes, this was reported recently. Apparently there’s nobody on the prism team able to work on it yet for the current version of Slicer so the older version must be used.
