How to reduce size of 3D imported models in S3D ?

[Benjamin2557]

Hi guys,

I'm trying to understand how to edit .obj files with a 3D editor (I use 3D builder in my case).
So I modified it successfully but when I import the edited .obj file into a .dat file with Silent 3ditor, the model appears a lot bigger ! : o







Someone knows how to fix it ?
I searched on the internet for hours, I understand nothing guys
