Hello everyone,
My render viewport is displaying some thin withe lines on my subd. Converting to nurbs seems to solve the problem (not always) but it needs a few clicks… I don’t know if anyone has ever had this.
Thanks in advance
Hi Antoine -
Please run the Rhino SystemInfo command and copy-paste the output here.
Also, please post a simple 3dm file that demonstrates this behavior.

Making a “simple file” seems to get rid of the problem. I am assuming this is a performance issue ? I did a quick video on the file had a problem with. Moving the part also seems to get rid of it.
Not sure whats happening
does your material have a displacement channel?
it looks like the seams are tearing due to the displacement.
It would be useful if you could share the file you used in your recording.
Here is the file that is causing problems. I’m pretty sure it is because of the image textrure and maybe the uvs. I don’t know. Thanks your replies.

Hi @Antoine_Jacquat ,
Try the command PackSubDFaces when you see this issue in Rhino 7. I had reported something similar four years ago (https://mcneel.myjetbrains.com/youtrack/issue/RH-62772) that could only be properly fixed in Rhino 8. That command helped in Rhino 7 though when this intermittent issue was seen.
With that said, I don’t see the white lines on your model here in Rhino 7.37 or 8.15 so it may be system dependent as well.
HI Brian,
That was was another good reason to upgrade to Rhino. It did indded fix the problem.
Cheers everyone.
