Square artifacts when rendered in Perspective Artic Render mode

Anytime any perspective render done in ARTIC RENDER mode I get these square artifacts.
What is the remedy???

Hello- please run the SystemInfo command in Rhino and copy/paste the results here.

Hello- System Info looks reasonable to me - is your image above from the viewport or from printing?


Printing to image file as well as when printing to PDF… same problem. Only happens in Artic Render mode and that is the number one mode I use for renders as system chokes in raytraceing.

@DavidEranen - is this something you can help with?

@TavVal - the scene you show should not give raytracing any trouble - does it not work here?
Can you print correctly from a Rendered mode viewport?


Everytime I try raytraceing the system slows to a crawl and in under a minuate Rhino becomes unresponsive.

Hi a @TavVal i assume your viewcapture pixel size is bigger than your main monitors resolution?

I had similar artefacts appear on a dual-monitor setup with big-ish pixel sizes for the capture.

Try unplugging one monitor or setting the capture size to something less than your monitors resokution to see if that helps. What i typically do i having a capture size of 1080p and using the scale option i can get my desired final pixel resolution.

Let me know if that helps or the issue is something else

So I have been trying different things and this is what I found:

  1. When the “PRINT TO EXTENTS” option is activated on an ARTIC VIEW render to file or print, it causes this square rendering atifact. As long as I set 1:1 and then SET VIEW it works fine.

So it seems specific to useing the PRINT TO EXTENTS in ARTIC RENDER MODE when printing to image.

Hi @TavVal,

I’m not able to reproduce this issue. Can you send me the model so that I can try to do exactly what you are doing?
