Subdivisional Pinching and Artifacting Issues.

MagicFlyingBus

Hey Polycounters, 

I've been banging my head against the wall on a few problem areas on a Henry45-70 receiver I've been making.

I can't seem to figure out how to solve the topology so that it subdivides smoothly. 



Help would be greatly appreciated!

Are the unsmoothed edges actually connected? Have you removed edge creasing?

Weld the vertices and reset the normals.

MagicFlyingBus

@antweiler  Yes they're all connected, no crease added. 

@C86G  I am unsure what you mean. If I do that then I will lose the hard edge that I want to keep.

You could send me the obj and I could have a look, if you want to : )

@C86G Sure https://drive.google.com/open?id=0B2R8idP-OPYpd1hJRjl1bVhJaTA

Your edges are waaay to hard! Smooth them and your pinching problem will get less visble. Also, if I read the geometry correctly, theres a round shape connected to a hard/planar surface. Thatßs always a bit tricky and the pinching that occurs is totally normal for that geometry and that toplogy.

This is far from good, but gives you an idea how to tackle it:

try these patterns

@C86G Danke, I'll try it out, but from my understanding that tanks the shape. I'll work with it. What do you when you say my edges are way to hard?

@Travis C Cool, the last one is currently the one I am running with for that particular area. From my understanding in the image it's cool to just let the N-gon go instead of trying to quad everything?
