I’m seeing an issue where the Perspective Viewport when set to “Rendered” mode is displaying nothing but black. This happened three times in separate files under specific circumstances.
If the resolution under “Rendering and Quality” is changed to “Custom: 1920 x 1080 (16:9)” AND a view constraint for example “Target to Path” is selected to a curve.
I did this with the “changing the resolution” step first and “setting the constraint” first. Both ways cause the viewport failure. I verified to make sure something should be visible by toggling the “Shaded” and "“Wireframe” settings.
Hi Jared - you did not categorize your post and I put it in the Bongo category.
Could you clarify that you are only able to get the Rendered display to turn black if you involve Bongo?
Also, please run the Rhino SystemInfo command and post the result here.

Correct, only when a bongo view constraint is added does this occur.
now that you mention it yes, I was using “Rhino Render Next” those 3 times in the “rendering” controls while My Bongo render is set to “viewport render.” However I just tested this with “Rhino Render” selected first and the same error has occured. This I tested 3 times
Additionally, after this error has occurred, trying to set the Renderer back to “Rhino Render Next” from “Rhino Render” no longer works. When I Click on “Rhino Render Next” in the drop down, Rhino forces it back to “Rhino Render” instantly. This occured only once in my 3 tests.
@jsaxon18is - Could you please send us the example file and exact steps? I’m not able to reproduce this here, it seems to work fine with Rhino Render Next as the target render and view constraints.
What version of Bongo do you have installed? (Type in BongoAbout on the command line to get the version date).
glitch steps.3dm (11.6 MB) This file will glitch if I follow these steps.
Under “Resolution and Quality” set “Dimensions:” To either: “1920 x 1080” or “1366 x 768” or “1280 x 720” or “852 x 480.” it appears to only be affected by aspect ratio. not resolution.
with the “perspective viewport” active Open “Bongo View Constraints” and select “add constraints.” from the drop down menu select “camera to path” and select the purple line.
At this point the “rendered” Perspective Viewport should be just black.
Note: Toggling the viewport to “Shaded” reveals the object. and under “Resolution and Quality” setting “Dimensions:” to a resolution to something with a 4:3 aspect ratio will fix the rendered viewport.
I’ve tested this on my laptop step for step it doesn’t seem to occur. I’m thinking it must be hardware related. My GTX 1060 is on the latest nvidia drivers. is there away to test if its my graphics card?
Start Rhino and try to reproduce. If that doesn’t work rename the following folder: %APPDATA%\McNeel\Rhinoceros\6.0 to %APPDATA%\McNeel\Rhinoceros\6.0.backup
Start Rhino and see if you can reproduce the issue. Renaming the Rhino folder will reset all your custom settings, but you can get them back by reverting 6.0.backup to 6.0
