Has anyone tried to save a render as a jpeg2000 with RGBA?
I can get it to save OK but when I take the image back into Blender via an image input node, I can’t get the alpa channel to appear correctly.
When I plug the alpha channel of the RGBA image into a viewer node, I would expect to see all black where the background would be and all white where the object (e.g. default cube) would be.
I get this fine with png.
With jpeg 2000, I instead get a black and white version of the image - not the alpha channel.
Am I missing something? I’m simply selecting ‘Jpeg 2000’ in the format tab and switching to ‘RGBA’.
Thanks in advance.
