Hi, You should be able to do region rendering. Find the video attached below.
:/
So the steps to bring an existing CXR rendering to the vfb and select the area I want to re-render is:
1- open it in the history tab
2- click on the pencil button to edit it in the vfb
3- click on render
4- very quickly select the region before other parts of the rendering get ruined with noise
The fact region render is unavailable when editing the file is a bug.
Alternative solution that I cannot understand why the devs don't implement:
1- Click on open cxr from the vfb
2- select region
3- click render.
Why can't that be done?
Open, together with save, are the most basic functions of any software since the 80s.
I don't get it.
