easy question: smoothing groups or something like them?


#1

How do you smooth an entire mesh but have hard edges along certain edges? Max has smoothing groups. Maya lets you choose the edges and pick smooth/hard. What do you do in Blender?


#2

You can crease edges, shift+e I believe. Or if that’s not what you’re looking for, when you set smooth it only affects what is selected…


#3

Here’s a way to do it that’s a royal pain in the ass and creates extra verts, but it works:

  1. In edit mode, select all verts, and hit smooth.
  2. Deselect all.
  3. Select a group you want to smooth seperately.
  4. Hit ‘p’, and choose Selected from the pop-up option.
  5. This will make the selected verts into their own object.
  6. Go out of edit mode.
  7. Select both the original object and the newly created partial object.
  8. Ctrl-J to join the objects together.

You will now see a smoothing seam along the border of the two object pieces.

There are disadvantages to doing this, though, and it won’t work for everything.


#4

The solution is definitely to use shift-e to set the hardness of the edge. Make it about .85 or .9 and it will look like a right angle with a slight softness/bevel. Or just make it 1.0 for a total right angle (assuming the angle of the underlying polys is 90 degrees, of course).


#5

One note for weighted edges, shift EKEY to work you need to have SubSurface on with the render value set from 3 to 5 depending how tight you want the edges to be.


#6

As stated above, the creases feature will work for the renderer with subsurfs turned on. If you’re trying to make a lo-poly model with nice smoothing groups for gaming or other realtime content, though, you’re kind of screwed.
