I have a scene in Blender 2.8, Workbench render engine.
I want to render it, but with certain overlay’s showing in the final render. Especially the wireframe overlay (under geometry) and maybe the relationship lines…
I tried openGL rendering, but that didnt work… same with normal rendering (obviously)
Doing a viewport render gives me exactly what’s shown in the viewport as expected. Both for Viewport Render and Viewport Render Animation.
Build from yesterday - Windows 64 bit. It works as expected with all varieties of Solid Mode (Flat, Studio and Matcap) plus LookDev and Rendered mode. Whatever overlays are turned on render,
Cavity shading may affect OpenGL render.
On my machine, it may hide and minimize a little bit wireframes display.
But I did not obtain something as extreme as in your scene.
If it is still as is with a recent build, you may take a look at bugtracker and fill a report if nobody already did.
Try starting Blender via “blender --factory-startup” and see if it works then. Sometimes during development some stale user prefs may lead to weird effects.
You can also use from inside Blender “File -> Load Factory Settings” (save your work first, it also loads a new scene without asking), but I found it sometimes retains some of my settings, so starting from the command line would be better.
