I have here a strange situation today. On Blender 2.81 and 2.82, while trying to render a scene file, that I've been assembling for years, it strangely now keeps freezing at 98% and returns several "TIFFReadDirectory:Warning, unknown field with tag 18246 (0x4746) encountered"
...But I don't even have Tiff textures on the objects, they are all .png ...Some versions ago (from 2 months ago) render just fine, but from some point on, this error occurs.
Anyone knows what can be this related to? At least a clue?
It's surely not memory, I have a 12Gb Graphic Card (TitanX) and I can deactivate all collections (having just a few Mb of memory in use) and I still get the error.
Thank you very much for the attention!
Edit: I've found the reason of the problem! It was some TIFF images loaded on a no longer existing object and the freezing at 98% was due it being render a 2nd ViewLayer that had all the objects turned on: This view layer wasn't being used on the compositor and as such I wasn't seeing this render result in any place until now. Thanks for all the help!
