Shading question.

IStonia,
Check this picture these edges are visible but they have not to be visible:


But if I zoom a bit everything becom good:


In orhografic view they visible always, may be because polygons are so close to each other, is it how it should be?

This is video card z-buffer related. It will happen if far clip plane is too big compare to near clip plane and the geometry is too far away from camera.

How to be in this situation?

You can try changing your clip plane settings. There is no perfect solution.

I don't remember if this is default hotkeys or whether I set them a long time ago (or even if this will help your situation samardac).

I use and press 'Ctrl Shift Alt  LMB' all the time to activate 'View Navigation Tools > Selection Focusing' while hovering mouse pointer over specific parts of a mesh.

This brings the clipping plane into a sensible location and helps with the Z fighting.


In Maya I think this is dynamic everytime you tumble on selection;  essentially everytime you rotate around a specific part of a mesh the clipping plane and area of focus is set automatically.  I wonder if this would slow up navigation in Nvil if Istonia were to implement this.

I get this shading error a lot when working on small parts in a larger scene.

Is it related to your post or different ?

Makes it kind hard to select & manipulate things properly with these kind of display errors.

Edges are rendering more closer to the camera so they can stand out of the mesh. In your case, the edges are cut off by near clip plane. Try setting the camera focusing point to the mesh part of interesting by using "Set View Focusing Point". You can find this tool in the tool search. If it doesn't fix, try adjusting your clip planes, Edit > Preference > Clip Plane.

Thanks Istonia

Adjusting my near clipping plane from 0.1 to 0.001 solved it. Looks good now even on extreme closeup.

Tweaking clipping planes is not something I'm used to. I guess other 3D application do it internally automatically.
