I made a few accessoires for MMD Models, that need to be rigged to the specific model to look authentic. I´m using blender to make these and import the mmd Model as reference to weight paint it.
The Problem starts now:
When exporting everything and posing it in PMXe, the mesh deformation is not accurate anymore. I noticed my accessoires are rigged with BDEF algorithm so I changed it to SDEF like the rest of the model. Still not good. The bones used for the accessoires are the same as the respective body bones. I tried to us seperate ones and parent it to the body. Well, futile... Even trying to weight it in pmxe directly never brings it to a close fit with the body. I tried changing the SDEF Settings manually, (e.g. copying the values from the body vertices to the ones from the accessoire.) Also nothing. It appears there is some Information about the vertices that I don´t know about or cannot see.
Here I used a rigged test leg with a small grey pipe going over the knee:
How do you rig your accessoires, if at all?
Any idea what I´m missing? I would really appreciate any help. Tried to solve this problem for almost 3 days now.
Here is the test Model I made to show the problem:
