Short description of error
When exporting an .fbx with shape keys, the model exports correctly to any other software, but when that same model is re-imported on Blender 2.81, no shape keys are read, the list appears blank.
Exact steps for others to reproduce the error
Create a monkey. Add a basis shapekey and make any modifications to a new shape key. Export to .fbx with geometry selected only.
Open any other software (modo, max, etc..) import the .fbx. Shape keys are read correctly and they do appear with 0-1 parameters. Import the same .fbx model into Blender 2.81, shape keys are gone. No 0-1.00 parameters appear.
