How does rounded edges work?

How does rounded edges work? I never got this to work.
Import a box. Set rounded edges - and nothing happens. Someone please explain.

You need to weld the mesh first. Pls see the Edge Rounding section of the manual at http://render.otoy.com/manuals/Poser/?page_id=298.

Box is welded. Ran the script anyway but still nothing. Radius= 0.1. Result:

I suspect the mesh welding that Poser is doing is corrupting the normals. Set the smoothing angle to 80 in the plugin Setup and then use a Rounded Edge Radius of 0.005.

That doesn't work either. I also tried in Standalone. Even cleared my default settings but still no luck.

Try this orbx.

Thanks. But no luck with that either.

Zay - that has the edges rounded. If you set Rounded Edge Radius to 0 you will get a much harder edge on the cube. If you want a higher degree of roundness, use the Octane subd functions.

I thought it was broken but it was the distortion that put me off. Seems I can't go higher than 0.001 without distortion. I can't use SubD if the object is not made for it and I was hoping Octane could do much higher radius. I guess I have to model that.
This is max without distortion.

My experience has been that IF the mesh is watertight (ie the vertices are welded) AND the normals are correct, subd works great. The main issue is that the Poser weld process kills the normals, and doesn't weld that great either. But if you model in another app and import into Poser it should work well.

I was hoping Octane could do much higher radius.

My understanding is that the round edges work better when the amount if edge rounding is a lower proportion to the polygon side. So bigger polygons = larger amount of edge rounding.
