Problem with maya import unreal engine

First of all I’m using google translator because I am Brazilian.

I’m having trouble with modeling, I model in Maya and I export in .fbx, when importing the unreal is with tiny dimensions and a crash box on the object and would like to continue with the same proportions and with real collisions as materials unreal

Hi, can you post a screen shot of what the object/model looks like?

This should help.
