Mesh Fitting

The Mesh Fitting options are better explained using another scene with two characters.

Here are two characters in DAZ Studio. The gorilla and the mafioso are both based on the original Genesis character, so the underlying mesh is the same. The result in Blender is very different depending on how meshes are fitted.

With the two Unmorphed options (Unmorphed Shared and Unmorphed Unique), the Genesis character is loaded without any modification. In the first case the characters also have the same gorilla texture because they share the same mesh, and in the second case the unique meshes have different textures. With DBZ File fitting, the result looks very similar to DAZ Studio.

DBZ AND MULTIPLE FIGURES by Alessandro

Please note that dbz is designed to import a figure in world space without transformations. It doesn't fit to import multiple figures with transformations. Below an example where we import two figures, the second is moved and rotated from the scene center and we see the bend axes in the armature are wrong. This is a known limitation and not going to be fixed.

On a side note, to work in blender it makes sense to import one figure at a time and assign each figure to a separate blend file to link on multiple scenes, so this limitation doesn't affect the common workflow. But it is blocking for people who wants to import multiple figures within a scene.

update. In version 4.4 of the addon there's a new global setting "keep roll angles" as an attempt to fix this issue, but it doesn't always work. However, it is also provided a new tool: setup > rigging > figures > "copy roll angles", with this we can copy the rolls from the unmorphed armature and this always works fine, but it is to be done by hand.

steps:

  1. import the figures as unmorphed and dbz
  2. on the unmorphed armature: pose mode > pose > apply > as rest pose
  3. "copy roll angles" from unmorphed to dbz

update. In version 4.5 of the addon the issue is fixed we can import transformed figures and the rolls are preserved correctly. As a consequence "keep roll angles" is removed as no more necessary. Also "copy roll angles" is no more useful.
