I have this odd problem - my texture is showing up purple in cycles using OSL but the code is correct.
At first I thought I was just messing up the path to the image, but then I got it working using a different image. It seems it doesn’t work when I used an image I saved from Blender - in my case it’s a normal map baked and then saved to disk.
Even if I open the saved image, and re-save it, or even export as a different type, no luck. The only way I can use it is by opening a non blender saved image, pasting it over the top and exporting it.
I can’t figure out what property of the image saved in Blender is stopping it from working. Any suggestions?
So I had a chance to try to get to the bottom of it - I didn’t, but I found a solution. Having two identical files (copied the data in a hex editor) still results in one working, and one not (the blender one not working, the one created fresh in ms paint working).
The only solution I can find is to rename the file, or originally save from blender, with capital letters. Yeah. So for example:
-saving as ‘test.png’, fails
-rename to ‘banana.png’, fails
-rename to ‘BANANA.png’, works
-rename back to anything with all lowercase, fails
When I save from blender straight to ‘TEST.png’ it works.
Frankly I have no idea what’s going on, it’s pretty hard to get to the bottom of it because a lower case name will sometimes work if it isn’t created. It’s inconsistent in this regard, but consistently works with capital letters in the filename.
Anyway this is a solution for me I suppose and I post it in case someone else comes across this problem.
