Hi Everyone, It feels like every 2 years I look for a solution for edges of objects being seen through other objects/surfaces. TestZBiasFactor used to be the band-aid for this problem, but I’m finding that it’s not working in the later releases of Rhino6. If it was just an issue in the viewport I c…

maybe this thread helps a bit: [image] Viewport accuracy / Arctic (with Outlines) Rhino for Windows Hi! Im working on an installation manual, and found out that Arctic with outlines (rendered materials) is a perfect way to do it. There is just one drawback. Our products…

Hello - it does depend on the overall size of the scene - are these scenes large in extent? -Pascal

Thanks for your responses @Gijs , Yeah, that’s about where I ended up last time I looked into this. I didn’t know if the depth buffer precision was improved but doesn’t agree with my GPU. @ Pascal, it’s pretty big, the perimeter of all objects is 380’x400’. JRT

@pascal , do you know if Mcneel intends to improve the resolution of the depth buffer any time soon (assuming it hasn’t been addressed)?

[image] jtrudeau: Mcneel intends to improve the resolution of the depth buffer Hello - I have no idea whether that is up to us, or OpenGL, or what… @jeff will know… -Pascal

Is there a work-around for this or an underlying issue causing the problem that I’m missing?. I can’t even print from Rhino anymore because the artifacts are so prevalent. (see below) [Capture]

Hello - I would at least try hiding stuff that makes the scene large in extents, outside the are you are printing and see if that even makes a difference. I could be wrong but my suspicion is it (problem) has to do with the size. -Pascal

The last image I attached was from a scene with only 1 object in it and I’m working off the world center. The extents are now pretty average in size and similar to what I use when I don’t experience this issue. It was also exported into a fresh scene. I’ve tried several different GPU drivers as well…

Is this a standard Perspective view projection, or a Parallel, or Two Point Perspective?

Hello - can you please post or send us that smaller file ( tech@mcneel.com ) with a link back here in your comments. https://mcneel.myjetbrains.com/youtrack/issue/RH-56674 -Pascal
