I Used Blender Maximo to UE4 Converter addon and Rig
incase you are like me who didn’t find an answer, I struggled with this and i will say how i got my answer in the exact steps
- i went into blender and changed my units to metric and set the slider to 0.01, the that i left out was i didnt set the length to centimeters
- I then selected both my rig and model(selected model first rig second)
- i scaled them (I cant say up or down cuz I did it until it was the right size)
- i then applied scale (both of them selected)
- i exported with these settings

PS: When i used Maximo to Unreal Engine converter plugin, i turned off apply scale as it gave problems
