For some reason, I couldn’t get a screenshot from blender this time, I’ll upload one later…
Anyway, I have got a subsurfaced object, and on a side of this object it is a complete flat face. In this I am wanting to make a small box that extrudes inwards. However everytime I have tried with different options, with subsurfacing it looks terrible.
Terrible, what I mean it turns into an eclipse. I shall tell you what I have tried, subdividing the box before extrusion, setting the crease to 1, but acts weird, extruding multiple times, but the inner box still is circular.
To do this would I have to use a kut tool on each corner and then extrude inwards, or is there any other method.
You’ve got something weird going on, Dunno what it is. If I have a flat face, I select 4 verts, extrude them inside and set crease to 1, it’s square. You must have some extra edges hiding in there somewhere or something, or your normals are flipped crazy.
I think I have found what I done wrong, after setting the crease I went and extruded inwards. After just trying with grap and moving along the y-axis it seems to be square, but rough, however I think I can sort out that. Thanks for your help, as I wouldn’t have got around that problem!
I have just tried it properly tonight but still setting the crease to 1 on faces around the one I have extruded in, I still get the problem, which I thought had disappeared. I have got a screenshot, of the problem I have had.
This is a bit confusing as I would expect it to work properly. Can any explain?
thanks Luke
Edit - -
Right I have set the crease to a lesser value around 0.6-7 and it looks better, as you can see in the photo. But even with sub-surfaced at 4, it looks pretty bad. Would I have to subdivide or loop cut the face before hand, so it looks smoother.
Select all the edges again and do a shift E 1.0 again (or Nkey to open the Transform Properties Box and set the Median Crease W to 1) . That should make all the edges sharp. But if you’re going to do that, why not simply disable subsurf in the first place and make do with the lowpoly version ?
I try to avoid using edge creasing, though and add extra edge loops and slide those to sharpen the corners.
What happened in your example is that the newly created edges from the extrude operation have crease values of zero. You said you set the edge crease before doing the extrude. You could fix the problem somewhat if you selected the new edges, also those diagonal ones in the corners then do a shift E 1.0 on those.
This seems to work okay. I understand that creasing isn’t a good option - was in a tutorial, but for now is the only viable option for me. Anyway I tried subdividing a box and setting ever face in between a crease value 1 - I won’t need it that sharp.) And it actually worked and probably now I can have some smooothig on it to not make it look weird.
