Maya 2016 - Quad draw mesh line rendering issues

Spicypixel

There seems to be a bit of a rendering issue involving the Viewport 2.0 rendering of the Overlay Append Mesh lines (though the same effect is present with regular wireframes). Using the legacy renderers seem to have their own bugs like when holding tab to draw a line of quads causes the overlay append mesh lines to vanish making drawing a line of quads quite difficult, and the performance of the viewport is reduced considerably.

Is there a setting in the viewport controls I've overlooked to try and rectify this? I've tried to change the wireframe anti aliasing levels but it doesn't really change the effect zooming into a mesh has on the culling.

I've included screenshots to demonstrate.





Doing retepology is much more difficult with the lines embedded in the live mesh, any help would be welcome.

Edit: this issue doesn't manifest in orthographic mode, but you can't tumble orthographic mode like in 3ds max.]

Edit2: Frozen/xray fixes the issue at the cost of making the mesh semi transparent as expected.

maybe its a clipping plane issue. In your camera settings reduce the far clip plane.
You cant tumble orthographic cams, bit you can make the cam non orthographic by disabeling the tickbox in the cams settings. I think its better to create a new camera and set the angle of view to 0, which has almost the same effect .

Spicypixel

Good call on the angle of view reduction even if it's a bit hacky, least it's usable for the time being unless someone has a better idea to reduce the issue.

Try changing your camera clip plane values, it seems to interact with the quad draw visibility somehow.

Angle of view at 12 degrees and near clip plane at 0.001 seems to work.

Thank you for the camera's settings Spicypixel. It works fine now.

When working with transparent materials, the sorting issues get really annoying; but in the viewport settings, if you change the method to "Depth Peeling", those issues all go away. Could work making the mesh's material slightly transparent, with the viewport's "depth peeling" method turned on.

THank you! This has bugged me for a long while, so much so I had to go to Topogun for fixes, now I should be able to stay in Maya for quick changes.

Cheers!

This is still happening to me with the latest SP4. Clearly a bug so, so make sure you report it.

This is not a bug, it's exactly what should be happening, autodesk just didn't realize that it's highly inconvenient.
If a few verts are placed on the surface of the mesh, the edges and faces connecting them will be inside the surface with greater curvature.



I use a pymel tool I wrote to deal with visually layering the meshes while they are actually still on top of each other.

This really really really old blog post has some details (although the latest version available for download has improved since then)

I've used this tool with quad draw and other maya tools for the past few years for all my retopology needs.

I understand how depth words, but I'm not so sure that's the intended behavior. If you switch to the legacy viewport and have "Overlay Append Mesh" on, depth is ignored and the object draws on top of the high poly. I understand that the legacy viewport is, well... legacy, but wasn't NEX originally made for older versions of Maya before viewport 2.0 was a thing?

If that's not supposed to happen, what's the point of "Overlay Append Mesh"?

Switching to the Legacy Default  viewport, it'll help. yayyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 
Thanks

Awesome thanks!!!
