About datastruct of Blender model

[szhang963]

Hi, I want to ask you something about how to convert the '.fbx' model to the '.blend' model ChatSim supported. I simply import '.fbx' to Blender and save it to '.blend'. However, I can not get the result, and report the message:

WARN (bke.customdata): source/blender/blenkernel/intern/customdata.cc:4319 CustomData_layer_ensure_data_exists: CustomDataLayer->data is NULL for type 46.

Could you provide some help if you have any time?
