Hi, so I have been trying to get this right, but I never get it to the point so it looks nice. It’s always some sort of pinching in the corners.
How should the topology flow in this area to avoid as much pinching as possible?!

Topology looks OK to me. Please post screenshots of the smoothed model without visible edges.

In general, it is impossible to eliminate those surface distortions completely when it comes to subdivision surfaces. All you can do is to move the vertices around and add more geometry/ edge loops to minimize the distortions.

Next time provide a view of your model smoothed so we know where the offending regions are.

Okay, maybe it was better then I thought. You only see the distortion in some angels.

Will do that next time!
Thanks for the help.
One question, you added these lines:

Wouldn’t I want to use as few polygons as possible? Does the model really benefit from these lines?
Thanks in advance!

Although you should be keeping your model as simple as you can, you should also keep all of the faces as square and evenly spaced as you can. You can add the edges and see if they help reduce distortion, then remove them later if they don't help. If the model will be bending or sculpted then you should make the faces square after you finish modeling.

If you want to add small details, you will always get pinching with a generally low polygon count. Nowadays, machines can handle a lot more, so the solution usually is to simply increase the mesh density.

Okay! Thanks again for all the help. It was really helpful! :bowdown:
Peace out!
