Rhino rendering object rotation texture problem

Hi everyone, I’m using Rhino 6 and Rhino Render.
I’m doing one of my first renders with texture mapping.
Maybe it’s a stupid mistake…

This is the render output before I rotate the object of 90°

and this is the result after the rotation

Any suggestions?



I’d need to see the 3dm to know for sure, it could be the mapping method used or the axis you rotated the texture in. Post it and I’ll take a look. You can use the Export command to save out just the current selection as it’s own 3dm.

Hi Brian,
thank you for your answer,
the horizontal object is the first I made, the vertical one is a rotated copy.

This looks like a bug when the render mesh has very few polygons in it. I filed it as https://mcneel.myjetbrains.com/youtrack/issue/RH-57761 for future reference. It doesn’t happen in Raytraced mode if that is an option for you as well.

A workaround for Rhino Render will be to make a custom render mesh with more polygons for the object prior to using Unwrap. Unwrap will then use that new render mesh preventing the issue.

Thanks for the report.
