I tried to apply a Subdivision Surface on a part of my object. I can't keep the angles sharp, they all turn into rounded angles.

The angle before applying the Subdivision surface... enter image description here

...And after enter image description here

In order to keep hard your edges, use the Crease. You find it on the right

enter image description here

The crease makes your edges purple, in order to show you wich one will remain hard or not.

Usually is set on 0.00 . . . Max it from 0.00 to 1.00 and your edges will keep their shape after a subdivision surface.

For example: Before subdivision

After

  • Thanks Fuboski. I tried and it works perfectly. Do I need to apply an Edge Split? – Grobby Sep 26 '16 at 19:11
  • It dipends . . .take care: edge split will need with the shading not for the subdivision surface. In order to undertsand better their function i suggest you this thread http://blender.stackexchange.com/questions/734/how-to-smooth-shade-an-object-while-retaining-hard-edges – Fuboski Sep 26 '16 at 19:15
  • @Grobby if you are keeping the model in Blender exclusively then by all means yes if it helps but I think adding supporting geometry (edge loops) is an equally favorable option. See http://blender.stackexchange.com/questions/734/how-to-smooth-shade-an-object-while-retaining-hard-edges/735#735 for some tips. – iKlsR Sep 26 '16 at 19:15
  • @Grobby if I answered your question please tick it as correct (the V) in order to close this thread – Fuboski Sep 26 '16 at 19:17
  • Where can I tick my question a answered? – Grobby Sep 26 '16 at 19:25
  • @IKIsR I just read you post. Is it better to use the edge loops or the Mean Crease to make sharp corners? – Grobby Sep 26 '16 at 19:27
  • The V is near the beginning of my answer on the left; there is the 1 between 2 "arrows" (2 triangles) . . . the V is just below. – Fuboski Sep 26 '16 at 19:35
  • @Grobby Sorry I missed this, the use case largely depends. For high poly models or stuff you export I think edge loops are better, for anything not the focal point or will remain lowpoly or inside Blender, creases can be useful. – iKlsR Sep 30 '16 at 15:59
