Rounded corners on walls

[DrakeCanyonArchitecture]

I'm looking for a way to make renders more realistic. A lot of walls such as stucco, drywall with bullnose corners, stone walls etc, are rounded or irregular and not a sharp 90 degree corner. I tried a few void extrusions but they didn't look great once rendered. Is there a way to round some of these instances. I used a 3/4" radius sweep on the parapets of a Santa Fe style home recently, which worked out okay, but it feels like there should be a more efficient way of doing this. As far as the stone and trying to get that irregular look, I think the best way to handle that would be in photoshop.

I create parametric generic family with a void, place it at wall corners and use Cut Geometry.  Make sure your finish layer is thicker than the radius so that when you cut the corner you are not seeing the core.

Another method is to model separate small/thin radiused walls that have only the exterior layer material, the use Join Geometry to join to the "regular" walls.

Look into PBR Materials.

I don't know what you mean by this.

Man, lots of great info here. @ToanDN, I think that must have been the issue I was having with the void extrusion. I was seeing some white shining through and it didn't occur to me that that was probably what I was seeing until you mentioned it. It was a stucco wall with a layer of foam under the stucco. I will give these a try and thank you @barthbradley for the links to those sites. I've used some other PBR sites but haven't seen these yet.

Can anyone give a step by step on how to create bullnose corners? How is a parametric family with a void created step by step?  What does the void do if a round corner is desired? Is the generic wall family the correct one to start with?
