4.19 - EXR Image Sequence crashes UE4

Hi there,

We’re trying to emulate The Mill’s real-time “The Human Race” film and one of the first things i’m trying to do is get an HD (1920x1080) 16bit EXR sequence to be read into UE4. I have made several different sequences with different compression settings and all of them crash the editor after less than a second of playback (Image Sequence reader via MediaPlayer)

I can see it buffering up and see a few frames before the whole editor is brought down.

Is it a known bug ?

Tested the new Hotfix 4.19.1 today and the same crash occurs.

Thanks,

Thanks

I just did some experiments on 4.18 and have found that Unreal does not like all types of EXR. I exported several ERX sequences out of Davinci Resolve. I output as both 16bit/half and 32bit/float in the different compressions.
Here are the results:

H-ZIP   Good
H-RLE   Good
H-NONE  Good
H-PIZ   Never Plays
H-DWAB  Never Plays
H-DWAA  Crash
F-NONE  Good
F-PIZ   Good Slow
F-RLE   Good
F-ZIP   Good
F-DWAA  Crash
F-DWAB  Crash
