I would like to request a feature, the ability to load a CXR file into the Corona VFB window, it is very lacking when working with heavy scenes, where a lot of memory is used and preparing geometry takes a long time. I use the “Resume file” function, after which 3ds max immediately starts rendering, loading geometry, and so on, I have to immediately press cancel, so that in quiet mode I can set Regions. This procedure takes up working time.
And there is an opportunity to fix such a problem. I have a project that counts 30 hours, halfway through I noticed that I didn’t turn on the grass, I stop the render, select the Regions section, count to the noise value I need, stop the render, remove the Region, click the render ,the render starts counting from the beginning, instead of continuing. I would be very grateful if you would implement this features
Hi,
I stumbled on this post while searching for a way to load cxr in the corona vfb.
Is it still not possible to this day ?
If not, how do you corona users tackle such a simple task as doing a region render on a previously rendered image ?
Hi, this is not yet possible, but we have it logged as a feature request.
As to your question, currently you would have to:
Save your render as CXR
Open exactly the same scene which was used for the original rendering
Go to Render Setup > System and disable “Clear VFB between renders”
Then use the “resume from file” option (click and hold on the VFB Render button or go to Render Setup > Scene > Resume from file), stop rendering (at any time, even after just 1 second). At this point you will end up with a Corona VFB with your CXR file loaded in it.
Then make some adjustments in your scene, and region-render
I can understand that the feature requested here would make the process much simpler.
Thank you very much for the detailed explanation maru.
This is exactly the same workflow I figured out by myself. The part where I had to resume the render then stop it immediately seemed odd and I thought I missed something or was doing it wrong.
Fingers crossed for the option to directly load a cxr in the frame buffer.
As of Corona 14, there are two ways to load a CXR into the VFB:
Drag-and-drop into the VFB - this will load the CXR into the VFB history and then you can go to the History tab and click the “show and edit” button (pencil) to edit it
Go to the History tab of the VFB, click the “Load CXR” button, then click the “show and edit” button as above
