I'm trying to make a simple ramp shape with a cube. I applied a bevel modifier to a single edge, then another bevel to all edges, and finally a subsurf modifier to make it smooth. However, the subsurf causes artifacting. I know this is due to the underlying geometry, but I don't know what the most efficient way of fixing this is.

I'm trying to understand the flow of this shape because I'm working on a python script to make it for me (for learning purposes). Currently I've just disabled the subsurf modifier, as it looks okay without it. In the future though, I want to figure out how to produce that shape without artifacts.

Any ideas?

I think you should be OK with just the two Bevel Modifiers - the first one with the weighted edge (highlighted below), and the second with default settings. Shade Smooth afterwards to make it smooth without the need for a subdivision Surface Modifier (which almost certainly will cause artifacting under these conditions).

Bevels

  • $\begingroup$ That is definitely not a bad result... I know that I can do that via scripting as well, so that's good. Cheers! $\endgroup$
