This is a quick fix that perhaps overestimates the point
of first geometry collision, but at least for now it should
allow models that used the old modifier and a too-big
bevel amount to not look awful.
The correct solution to this problem is much more involved
and I'll get to it later.
Now modifier takes a segments parameter.
Bevel edge weights will multiply the overall amount.
For vertex-only, you can give a vertex group name,
and the weights in that will multiply the overall amount.
The code for making a rounded profile edge at a vertex needed
a special case for when that profile is on the third face
(the one not touched by the beveled edge) when only one edge
is beveled and the three faces are not orthogonal.
Really was caused by a previous bevel making
a two-edged face, which caused other faces to
be dropped when copying a bmesh.
The quadstrip code needed to be more careful
to avoid creating two-edge faces.
Bulging still happens, but fixed the cases where it was obvious
because it destroys an otherwise straight 'pipe' by snapping
the vertex mesh points to that pipe.
Thanks for Sergey for finding the bug & patching, This fix works a bit differently.
Theres no need to allocate the customdata in the first place - since its written into. So add a flag for vert/edge/face/loop creation functions so they can skip customdata creation.
Sometimes it is impossible to have same offset from
both edges that are on angled faces. The fix here
at least doesn't distort the non-beveled part of the
model, and looks much better than before on bug
example, but is still not perfect.
- BMO_slot_copy now only copies compatible elements.
other minor changes
- don't use text.format(...), convention for UI scripts is C style string formatting.
- rename bmo_edgenet_prepare --> bmo_edgenet_prepare_exec
- float/double warning in bevel.
- the resulting selection is now correct
internal details
- bev_rebuild_polygon() now only rebuilds polygons that are attached to a bevel vertex (was rebuilding ALL).
... need to take care we don't leave faces pointing to removed geometry, so far this works fine.
- bev_rebuild_polygon() uses stack memory for <32 size ngons to reduce allocs.
- skip hash lookup when removing bevel verts (use tag instead).
