Bleed Process Off
This shows various cutouts without performing post-process bleeding, i.e., the cutouts’ data is not modified by Mineways.
To see how bleeding helps, view this model: https://skfb.ly/JPH6
Please note: bleeding is in my opinion the wrong answer; instead, the renderer should be fixed. However, since I can’t fix someone else’s renderer, bleeding gets rid of the black fringing.
Also, some people like the black fringing, as it gives the decal a toon effect. My feeling is that if you want a toon effect, add the black outline yourself. Don’t rely on a rendering artifact (that might get fixed) to get this result.
