Just tried the first scene again with combined pass only into a TIFF output, fairly much the same issue with this message-
Traceback (most recent call last):
File "/Users/jamesmac/Desktop/cr_compile/releases/multi OS releases/crowdrender/src/cr/ui_operators.py", line 1106, in modal
AssertionError
location: :-1
This time the first frame rendered did save an image (it did save a single EXR the first time, but it didn't seem to contain much, it was only 180Kb), the TIFF it saved did have the rendered image, but only the first of the sequence and the error above...
Cheers
Mark
