EXR images display wrong channel in external programs #4747

Open RodneyBaker opened 1 year ago

@shun-iwasawa You may already be aware of this issue or it may just be a current limitation of EXR implementation but I am noting that EXR images rendered out of Opentoonz that are then imported into other programs are displaying incorrectly. It is as if the RGBA channels are perhaps reversed?

I see this in multiple programs but a free program where this can be observed easily is Mr. Viewer (LINK) image

Here I choose the Red channel and it appears to display the Alpha Channel: image

I was never quite smart enough to figure out which channels are swapped here. I think it might just be the red and alpha channels are swapped.

BUT... I post this not for this bug report but for some actually really good news. I just discovered that toonzscript can use the EXR format. That is most outstanding. :)
