Q.
I rigged the “Arm” mesh and bent the bones.
The intention was to have the Lower Arm part above the Upper Arm, but it didn’t turn out that way.
The “Arm” mesh consists of 1 piece, from the Upper Arm to the Hand.
How do I modify the rendering order within the mesh, i.e. the depth?
A.
The rendering order of meshes is determined by their depth in the Hierarchy, but the order of vertices within a mesh is random by default.
However, the user can change the rendering order by changing the depth of vertices.
The following manual explains how to change the Z-Depth of vertices.
