Blender files have to follow a set of rules:
Each article has to be available as Blender Collection.
Each node name has to consist of a→z, A→Z, 0→9 and _
Blender Collections can contain a Sub Collection with a name containing the substring DUPLICATES These are not exported and shall contain copied meshes for Blender reasons like Armrest_L.001 The Original Geometry e.g. Armrest_L has to be available outside DUPLICATES collections (see example).
Note: “.” as part of a nodename may only appear inside DUPLICATES collections (and therefore never exported) Note: Collections whose name starts with “_” are ignored and not exported. Tests or helpers can be added this way.
Geometry normalmaps should be attached to a material attached to a Blendermesh. Shared Geometry normalmaps should be attached to a single material that is applied to the respective meshes.
If the creation of additional Meshes is contracted, they can live on the root level of the blend.
