Found while making Layonara's missing brownie robes and cloaks: 340 models, robes for both brownie phenotypes and cloaks. They were checked in game against the human versions, front and back.

variants

• Robes with no skin (backpacks, pieces hung on bones) are refitted instead of refused.

• The robe's own bones and attachments are placed at their offsets scaled to the body:

  • flaps, coat tails and skirt panels;
  • capes on shoulder pads;
  • backpack pieces.

  Across and front to back the scale is the chest's; up and down it is the hip height. What hangs from them is scaled the same way. Before, they kept the human's size, and a cape reached below a brownie's feet.

• Only body bones the template lacks still come from the skeleton, or stay out (a wemic's robes have no legs).

• A bone's axis now comes from its child bones only. These no longer set it:

  • a child under 2 cm from the joint (it tipped Beamdog's HD robe 30);
  • the robe's own bones;
  • meshes that are no bone (a backpack's pieces turned the torso backward).

• Each mesh uses its own node's transform, not the first node of its name. A server's robe 202 has two Cloak_Base.

• A cloak built from the skeleton takes body bones beside the torso (neck_g) from the skeleton.

• The body's animation set and scale. A robe on the source body's animations (a_ba, a_ba_coat, a_fa_skirt) gets the target body's set at the target's animation scale, as Bioware's race versions of robes 20 and 21 have (pmd0_robe020: a_da_coat at 0.66). At scale 1, brownie robes floated over their heads in game.

Fit accuracy against Bioware's and the hand-made versions is the same as v4.13.0 or better:

	v4.13.0	now
Brownie bone copies	2.02 / 2.20 cm	2.01 / 2.17 cm
Stock robes, skin	3.42 cm	3.41 cm
Stock robes, bone copies	2.65 cm	2.61 cm
Cloaks	unchanged	unchanged

check robe_torso_turn, repair --fix-robe-turns

On a worn robe, the game draws a node whose parent is torso_g as if it had no rotation. This was found in game and is written up as plenarius/nwn-mdl-spec#9 (MDL-NODE-050).

• The check reports such nodes in robes.
• The repair (part of --all) puts the rotation into the node's geometry and its children's placement, leaving the node unrotated. The model is drawn as it was built.
• Left alone: body bones, dummies with nothing under them, and nodes the robe's own animations turn.
• Results: nothing in the base game is flagged. Layonara's 608 affected robe files were fixed the same way in layonara/nwn-haks#36 and checked in game.

New tests cover each fix; they fail without it. Neither change touches the decompiler, writer, parser or compiler, so the Python port needs nothing.

Not in this PR: cleanmodels-qt doesn't offer --fix-robe-turns as a Clean fix of its own yet; it only gets it through All Fixes.
