Following on from a discussion in the #blender IRC channel - here’s how to create a simple panelled surface (using Blender 2.63a).
Final result:
-
this method relies on a low res base mesh as a starting point. It’s possible to use subsurface modifiers in conjunction with this method, but it’s a bit more involved so I haven’t covered it here.
-
starting mesh:
-
go to edit mode, change to face select mode and make sure all faces are selected (‘a’ key)
-
extrude individual faces alt + e -> Individual faces
-
immediately press [esc] key to to avoid moving the new faces
-
next, Mesh->Faces->Inset Faces or press spacebar and search for ‘inset faces’
-
in the Inset Faces tool panel (if the panel isn’t visible, press ‘t’ with the mouse cursor in the 3d viewport) untick ‘Select Outer’, set the Thickness to a low value like 0.0040. Offset Relative needs to be unticked.
-
extrude individual faces once more (alt + e), and this time extrude the faces out slightly.
You should now have a model with a panelled surface.
If anyone has problems with this method, spots a mistake or knows of a better solution, let me know :eyebrowlift:
