I was wondering if a checkbox to the rounded corners section of the material to affect only the same material could be added.
As you can see from the Render example.jpg it blends with a different material whereas it would be nice if there was an option to disable this. I use the round corners feature to blend the same material to give the appearance of the material melting into each other at geometries intersections which is particularly useful for welds in painted metal. See Render example.jpg and Viewport.jpg to see this effect.
Naturally this effect should be off by default I would imagine.
Thanks.
