subdivision surfaces gets messy

[duketogo]

I didn’t take modeling course yet, so this maybe not a problem for others.

Subdivision surfaces in the lecture worked good looking result,

But mine is still get messy with groove. I tried to modify model but topology went bad.

It would be great if modifying progress were recorded.

Hey @duketogo , what’s the in-subdivided topology look like in edit mode? My guess is that there’s a big n-gon right in the middle there. N-gons are fine to have, but if they produce results like this, then connect some vertices with the hotkey J to tell Blender which way the subdivisions should be going. Or, you could press Ctrl+T to turn the whole face into triangles. Otherwise they’ll all pile towards the middle like that which causes some parts to overlap. Hope that helps!

Turns into this when subdivided:

Here is a result. I see how it works.

The point is “cut ngon to triangles before modifier makes it ugly”

Thank you.

i find that you are saying  (N-gons are fine to have ) which i never heard of anyone in the industry.

it is considered to be  one of the most undesired topology in any 3d model 

especially games assets
