Natsura 0.6.3.0

Suite of bugfixes and stability improvements

• Removed many classes of bugs including "ghost" cooks triggered by python panels
• Updated rig definition for improved control
• Improvements to Assembly tools and workflow
• surface decoration "min width"
• fuse assembly rigs with simulated skeleton for detailed wind animation
• The biggest workflow change is the rig to assembly workflow. Now it is possible to simulate a set of branches or a tree and then "decompose" it into modules for use in another simulation. This unlocks the procedural power of natsura for creating species at scale.
• rig_merge ~ merges two rigs into one
• binds parents ↔ children across the join
• "fix parent id" + adjustable parentname
• later speed-optimized
• rig_rename ~ renames rig joints as a discrete op
• rig_delete ~ deletes rig joints as a discrete op
• rig_collapse ~ collapses rig hierarchy
• refactored to host shared rig utilities
• rig_rebind ~ rebinds skin weights to a rig
• remade from scratch (was very slow), then standardized and optimized
• rig_rename ~ renames rig joints as a discrete op
• rig_delete ~ deletes rig joints as a discrete op
• rig_collapse ~ collapses rig hierarchy
• refactored to host shared rig utilities

• multiple branch inputs, nested assemblies, extract subassemblies + atoms
• fixes and simplifies rigs
• added "absorb instances" toggle
• refactored onto shared rig utilities, removed redundancy
• moved "name corrections" up a level (was too deep)
• fixed class management (resolved a cascade of downstream bugs)
• viewport arrow made static
• instancify ~ pulls repeated geo out into instanced modules
• pulls out subassemblies, fixes up rig + skin
• transfers prim attributes too
• removes single instances mis-tagged as modules (re-found later)
• collapse-unused-parts now deletes fully-unused joints, not just reparents
• fixed broken "detect unused modules" check
• "absorb instances" toggle, internal-node refactor
• viewport arrow made static
• assembly_decoration ~ places decorations onto
• fixed invalid default parm (result shows on first placement now)
• passes name / localname / parentname / assembly_name through
• switched to parent_id internally (old branches lacked id_parent)
• ~100× speedup at high joint counts (nametopoi
• smarter rig reconstruction + joint management after deletion
• working preview mode
• assemblify ~ converts rig + skinned geo into one mesh stream for decorators
• scope reduced to that single responsibility

• added timeshifts for slider dragging
• robust fullpath-vs-name colouring

• defaults to assembly_name, added assembly_resource
• wind preview removed
• import_assembly ~ brings an assembly into the scene
• partition_assemblies pulled out of it (wrong level)
• partition_assemblies ~ splits an assembly into partitions
• extracted out of import_assembly
• build_assembly_rig ~ builds the rig for an as
• ly style
• treeparameterize ~ generates strands / parameterizes the tree skeleton
• new "use existing prims" mode (longest strands, no new prim chain)
• new modes: keep source prims, split by attribute (sub-primitive strands)
• added seam group + seam attrib (split strands at UV discontinuity)
• exports id_strand, id_parentstrand, id_sourceprimids, order_strand
• sourceprimuv transfer bugfixes, optimized parent-strand-id gen
• order_branches ~ orders branches for traversa
• computes dist instead of assuming width
• still flagged "needs more thinking"
• fuse_tree_rig_and_skin ~ fuses tree rig with
• stamps new prim joints with prim attributes
• copies additional attribs
• attribute_transfer_by_rig ~ transfers attributes by rig ownership
• now functional
• primsplit on input + edge transport to pick the correct prim per joint
