Multi part rendering using putImage

Silhouette
1

I am trying to render multi part exr using module’s putImage but not sure how it works exactly and how to get the renderParts() mentioned in the wiki
https://documentation.borisfx.com/wiki/sfx/index.php?title=WhatsNew

My goal here is to render out a multi part exr with layers in a roto node as layers in the exr output file.
Is this possible with the approach i mentioned?

Have you looked in resources/scripts/tools/renderer.py? That contains the entire rendering loop for a typical Silhouette render, including managing of Multi-Part output nodes.
Basically you create an EXR output module, create the file, and call module.putImage() multiple times, each with a different “part” name.
Look for “for part in output.parts:” in renderer.py to see how Silhouette does it.

Thanks! I have now managed to create the multi part node and managed to add some inputs but looks like i am doing something wrong when i try to add the code to actions.

I am referring to the actions “LayersToSeparateFiles” and similar ones for help but even when i create a new class inheriting actions, and have the execution code in the execute function, i can see the option being added to the actions but cant seem to launch a ui from there.
The code executes but does not launch a new custom gui .

I am using a QMainWindow instance, maybe this is causing issues?

Oh, you’re getting pretty complicated there. I don’t know if that would be supported.
Maybe try a QDialog instead?

I was actually trying to avoid that since i may have to modify how we are using some similar tools in different DCCs.
Will try a few different things and see if i can get it working without having to use QDialog.
Would dock serve better if i just happen to attach a custom widget into a new dock?
I am trying to avoid that way as of now but maybe a valid other option instead of popping new window.
Its just that i will have to destroy the dock when i am done with the tool since its possible for someone to click multiple times by mistake and trigger multiple jobs.

Yes, it should be possible to create and add/remove custom docks.
