Alpha Transparency with OpenGL Render of Viewport in 2.8

Hi, I have been trying to get a wireframe viewport render with alpha out of Blender 2.8 just like 2.79 and for some reason I can’t. Is it possible to do such a thing in 2.8? Any help is greatly appreciated. Below are a few pictures illustrating what I am trying to do.

Original Blender 2.79


Blender 2.8

No Transparency/Alpha in render

I played around for a while but couldn’t find a way to do it with the new viewport render (which I think is basically Eevee now). You can always fall back to doing it explicitly with a Wireframe modifier and an emission shader on the object and a Cycles final render, but obviously that’s a lot more work.

if you want to capture your viewport i recommand using the workbench engine, and then choose transparent in the alpha Mode button, a then hit F12

Edit : F12 does not capture the wireframe mode, and the viewport render does not capture alpha transparency when it’s in wireframe mode … is this a bug ?

It seems to be a “lack of feature” at least as far as I can tell. I’ll put in a bug and see what they say.

Fixed

Yep, fix tested working. Will be in tonight’s build so download tomorrow for the fix.

Set the renderer to Workspace, and then under Film set the Alpha Mode to Transparent and then you can do a View-> Viewport Render Image.

Works exactly as expected now. Thank you all!
