hello every time i import objects and fbx buildings they are extremely big in size what's the essay way to reduce them in size
2 things. Either just reduce the size in Buildbox using the scale. Or, resize them in blender(which is free). Just search Youtube how to resize fbx files in blender
As spicedbeangames mentioned, try Blender. It’s very easy to scale down/resize models there. There are tons of youtube-tutorials on how to do this.
