Short description of error
If the parent_type is set to ARMATURE (instead of using the modifier). The deformations are not shown in the viewport anymore. In rendered frames the deformation according to the pose still works.
(Changing to an Armature modifier works. However, we use a custom exporter which relies on models using the parent_type instead of the modifier.)
Exact steps for others to reproduce the error
- Take any rigged model (simple auto weighted is fine).
- Remove the Armature modifier and set the mesh object's parent_type to armature instead.
- Notice that in pose mode the mesh doesn't get deformed in the viewport anymore. (it does rendering a frame.)
