I want to render a single frame of a texture and then print it in the measurements 150x266cm at 300dpi, therefore I calculated a render resolution of 31488x17717px, which seems to be a bit of a problem with Blender.
I have tried rendering to TIFF but once it's done and I want to save it Blender crashes. Then I tried rendering to an EXR file with "Save Buffers" activated under the performance tab since I read in another thread that this will make Blender save the EXR file after each render tile is done (using single GPU) and even if Blender crashes (which t still does after finishing the last tile) I should still have a working file in my TEMP directory that I can use in Photoshop. Only thing is that no intermediate saves are being done, only a corrupted EXR file is being generated at the very end of the render process (not opening in PS and way too small).
I wonder what I am missing.
Anyone got an idea why this might be?
Thanks & greatful for any advice!
