Changes in Bone Targeting During Model Import/Export #156

Open kafeijk opened 5 months ago

kafeijk commented 5 months ago

I added an 'upper body2' bone to a model without a sub-standard bone (such as the MIKU model from early MMD). After importing the modified model into Blender and then exporting it, I checked it in PmxEditor. Previously, the 'upper body' bone targeted 'upper body2,' but now it has changed to a relative position. before: image

When importing the model, the head and tail are checked using EditBone, but it's not the EditBone type here. https://github.com/UuuNyaa/blender_mmd_tools/blob/d148bdbd520a0ddb2ffd0389a0217a297ad107f0/mmd_tools/core/pmx/exporter.py#L407C29-L407C83 I'm not sure if the current situation is due to the code or if the file structure is inherently like this.

Additionally, if the target changes, the local axes in MMD will also change accordingly. before: 无标题 after: 无标题2

20241015-141648 This seems to be the problem? I removed 'not' and it worked normally. isMovable in PE seems to indicate whether the bone can be moved. I don't quite understand what lines 270 and 274 want to do the opposite.
