Scaling from blender to unreal

I have made a model of my Office for VR purpose, I have made my model in Blender using MeasureIT addon so that my model becomes of exact real world scale of that of my office. But after exporting and importing it to Unreal, I am not getting that exact Size when i wear my HTC Vive VR headset.

When you export from Blender, be aware to set the World Scene measurement to Metric and the scale at 1.0000
In the export FBX settings, use the scale of 1.0 as well.

In the Import window in UE4, leave the scale at 1.0 too.

Don’t forget tho that the default character in UE4 is kind of a giant! (2 meter 10 iirc).

yes, i do had my metric setting, but when i import in unreal and i use play in VR i see that my height is much more bigger than that of my model…

Simple, change to metric and Scale to 0.01 still in scene settings. Dont need to change anything else
