Ok, hear me out, I'm going a little crazy here. Corona Daily Sept 26, Max 2023.1, Windows 10.
I'm trying to do a background override. I've done this a million times in the past without much problem.
Currently the scene is quite basic, 2 materials (both CoronaPhysical) on a large imported file. Though now I'm also testing on a completely blank scene with nothing but sun (clouds disabled).
Problem #1: If I set the CoronaBitmap in the override slot with the image I want to use, I get an Nan error. Every time. If I use a different image, I get no error. If I downsize my original image, re-save, different extension, different format settings, I still get the Nan. Again, this is only happening for the image I WANT to use. If I test a random image, no error.
Problem #2: Often the background override doesn't work at all. Just black. If I choose the same image from a different folder... IT WORKS!? Yes, I am using Dropbox, but still, if I test the image in a different (non-dropbox) folder it works, but also works in different dropbox folders. Just the original folder doesn't work for some reason. Very, very weird.
I know this is all a bit hard to follow from my rambling, but I'm losing my sanity a bit here...
Any ideas?
Edit:
Problem 1: This seems to have something to do with ToneMapControl. If I plug this into the background override scene I get the NaN eror. If I then and unplug it, save, re-open the NaN is still an issue. If I never plug in a TonemapControl this isn't an issue.
Problem 2: It seems if I load an image, ANY image, while IR is NOT running, the background is black. Even if I restart IR, the image will remain black. If I change the bitmap input while IR IS running, the image appears as expected, even after a restart of IR. Very strange bug, hopefully reproduceable.
