Title: 3DS Max/Corona saving out corrupted EXR's
Post by: RecentSpacesSam on 2024-07-02, 10:33:01

Hello, we've had a couple of projects saving out with corrupted exr's recently.
When viewed in Photoshop they display as completely white and Corona Image Editor shows the error:

Quote

Cannot operate with image file
"[filename]"

It is either incomplete, or not stored with a floating point precision.

3DS Max 2024.2.1
Corona 11.1

We can load the exr's through 3DS Max's frame buffer and resave, but the images still have problems (bad alpha for example)

Has anyone else experienced this issue?

Small update:
It seems these max files were set to 32 bit exr's and saving out something between a 32-bit and 16-bit exr. The file sizes were neither what they should be at 32 or 16 bit exr's.

Switching the exr settings to 32 bit and then back to 16 bit seemed to solve the issue (at least, so far)

It could be some 3ds Max issue. Please let us know if it happens again.
