When printing a layout viewport in Rendered display mode, parallel reflected projection, objects located at the world origin have a glare artifact only in pdfs printed via the RhinoPDF printer. This glare doesn’t show up in the viewport or using print-to-image-file or when using another pdf printer (bluebeam pdf). It is localized to the world origin.

Not seeing this in a quick test of your file in a fairly similar environment. Rhino pdf / Bluebeam are printing the same.

Are there any custom settings in the Display Mode?

Rendered.ini (16.0 KB)
Here is my modified Rendered mode.

Can you try it with the default Rendered mode except with shadows turned off?

5

Not seeing the glare artifact printing the layout via RhinoPDF with your Rendered.ini & shadows turned off.

Alright, thanks for checking. Not sure what’s causing it, but I was able to work around it by turning shadows back on and setting shadow intensity to 0%.
