View Clipping Only When Exporting Arctic or Rendered Mode

Hey,

I’ve been having an issue when attempting to export Arctic or Rendered display modes to an image file. I’ve tried both through layouts and through viewcapturetofile. There seems to be some clipping that does not register in the viewport (see below), but certainly loses information while exporting (see below).

While there are posts about viewport clipping (which are for the most part unsolved), this is happening only after export in specific display modes. For instance, shaded mode exports fine (see below). I’ve also noted this only happens once the resolution exceeds a certain size. Any assistance would be greatly appreciated - in the meantime I will continue to troubleshoot and provide an update if I land upon an answer.

Best,
Niko

Update: I dropped the resolution down to 300 DPI (formerly 400 DPI @ 30x40") and it seems to perform better. Can anyone chime in on what might be the cause of this? Am I just being unreasonable with the size of image that I want? Would this be a GPU based limitation?

This looks a bit like a tile alignment problem. When images larger than the viewport are captured, they are rendered in smaller images (tiles), and stitched together at the end.

Try this:
Temporarily turn shadows off in the display modes, then try the oversized capture again. Do the new images without shadows have the same issue or not?
