Unexpected Shaded View Display Behavior: Geometry Ghosted/Wireframe

Rhino Rhino for Windows

A file I’m working on just started having a weird display issue:

Geometry in any view with “Shadows” enabled in the display panel are showing as ghosted or wireframe in the viewport. While I’m panning/orbiting/zooming, everything displays normally. File isn’t particularly large/complex or anything.

I copied the geometry into an empty file and the behavior continued.

Un-Checking “Shadows” in the display panel fixes it.

My graphics driver is up to date.

I assume restarting my computer will fix the issue, but I’m curious if there’s another solution or any explanation of what’s going on.

Hi Dylan - if you disable Enscape in Options > Plug-ins page, and then close and reopen Rhino, does this behavior change?

-Pascal

Nope, no change.

Hi Dylan - if possible, can you make a copy of this file, delete most of what is in it, leaving some objects that still show the problem, assuming that they do, send us the file to tech@mcneel.com, with a link back here in your comments. If the problem is not evident in the sub-file, send the whole thing.
I’d also check with Elefront disabled, ( Rhino closed & re-started) though it seems unlikely to be the one.

-Pascal

Done. And in putting that file together, I found two potential culprits:

–When I exploded or removed block instances of a door latch that I had downloaded from the manufacturer (I believe it was this model), the issue disappears.
----It only worked when I exploded /all/ the block instances.
----I tried replacing the geometry inside the block with just a single basic shape, this had no effect.

–I had some objects set to different display modes using “-setobjectdisplaymode” command. When I changed everything back to default display mode or ghosted, the issue disappears. It seemed that it was having objects set to “Wireframe” that was causing the issue. When I changed objects back to “-setobjectdisplaymode -wireframe” the issue would come back, but I could set objects to “ghosted” with no problems.

Digging a little further, it looks like the issue occurs specifically when I use “-SetObjectDisplayMode -Mode -Wireframe” on a block instance

The issue doesn’t appear immediately, and more objects appear to be affected as I set the display mode of more block instances to wireframe.
