Short description of error
Batch exporting groups of models, Blender Scene scale of 0.01 with unit of centimeter, exporting option scale 1.00. exported models all have correct size in UE4 editor, but when I imported them into Autodesk Maya, they are 100 times bigger. Where if I export them individually, the size will be correct.
Exact steps for others to reproduce the error
Create bunch of meshes, make sure they all have uniform scale of 1.0, put them into different groups, select them all, do File--> Export--> FBX, make sure the exporter option scale is set to 1.0 and batch export is checked, export mode set to group and don't forget to check only selected.
Hit export button.
