Large 16bit & 32bit EXR File Export Broken

[Derek Bentley]

When trying to export a 32,768 x 32,768 pixel EXR file (either 16bit or 32bit) I get a hard crash (poof Affinity Photo 2.0.4 is gone).  The main reason I purchased Affinity Photo is to load and modify large 32k Terrain files in EXR format, so hopefully this can be fixed.

Hi @Derek Bentley and welcome to the forums. I'm using macOS but I had no difficulties exporting a couple of images of that exact size to EXR (32 bit). Perhaps somebody else using Windows could try it, too.

Hi Derek, 

Would it be possible to send a document to the following dropbox so we can take a look

Yes, I'll put some exr's in there to test.  Also just so you know I have plenty of RAM (64GB), and have no issues with these large exr's on my system in Photoshop.

I think I got it working now.  I was able to export several EXR's now, both 16bit and 32bit in RGB and Grayscale mode.

All I did was delete a 40GB file that was here:  C:\Users\Derek\.affinity\Photo\2.0\temp

The file I deleted was "PersonaBackstore.dat" which had somehow ballooned up to a whopping 40GB!
