I'm using Godot, but this issue happens with Blender too when I import the .FBX models. Here's an example of what I'm talking about using (left to right) the files ArcadeCabinet_low, BeerGlass_Empty_low, and BarCounter_low.
By default the scale is set to 0.1 when I import the latter two models, but the former is set to 1.0 - changing that still doesn't fix the scale issue though. I could definitely try to "eyeball" them and scale them in proportion to one another, but I was hoping maybe there was a way to avoid having to do that.
