- updating normals in py/api's mesh.transform() wasn't working and gave annoying print, disable this, script authors can call calc_normals explicitly if they need.
Don't create empty tesselated faces layers in edit derivedmesh, these are
being created on the fly so this will conflicted, and use loop data for
opengl attributes for edit derivedmesh drawing.
In fact there were several issues fixed (all of them regressions since bmesh merge):
- Creating navmesh crashed because creating new faces for mesh was trying to set
default values for all customdata layers in this face. This requires memory
pool created for this datablock.
Usually this pool is creating on creating datablock if there're some elements
to be stored in this block. In cases of regular primitive creating it wasn't
an issue because they doesn't create customdata layers, they only creates
geometry.
Navigation mesh creates geometry and customdata layers (CD_RECAST layer)
which used to confuse a bit custom data functions. Solved by ensuring there's
memory pool created for polygons datablock after adding new custom data layer.
Most probably it's better to be resolved on CD level (like smarter track on
changed amount of stored data and so) but prefer not to make such global changes
so close to the release.
- Toggling edit mode lead to loosing recast datalayer. Solved by adding recast
layer to bmesh mask so it'll be copied to/from edit mesh.
- Some part of code assumed raycast layer is in face datablock, some that it's in
polygon datablock. Made it to be in polygons datablock.
Kind of temporary solution to make navmesh working, probably it'll fail if one
will want to edit navmesh by hand after it was generated.
Proper way would be to ensure the whole navmesh things are using ngons.
This call is still needed when loading editmesh because some operations
are not creating CD layer for new loops (like crating new face) and
to prevent loosing all sculpted data when running disps correct
displacement maps should be allocated on loading edit mesh.
This feature did have a number of flaws and caused some controversy, so removal is the better option. Hiding nodes without prior connections would just hide all the sockets, leaving an unusable node. Better way is to use the ctrl+h shortcut to explicitly hide unused sockets when necessary.
* Replaced the hard coded viscosity presets with Python ones.
* Added version check, so older files load fine.
Loading new files into 2.62 also works fine.
data, and tool settings.
What exactly should be copied is a bit up to interpretation, but I think these make
sense, and things like audio or game data used to be part of render settings which
do get copied so at least for those it was a regression.
* When converting mfaces to mpolys, load external MDisp data in, add
CustomDataExternal struct to loopdata if needed.
* Fix multires modifier's filepath RNA functions to use ldata rather
than fdata.
