If i upload an FBX file or publish a scene from Unity into STYLY Studio, Is there any way to seperatly move or effect each element in the scene?
Or do i have to upload or publish seperate elements if i want them to be individually editable?
You cannot edit the scene if you upload a whole Unity scene. You can only move and rotate and scale the scene.
As you say, if you want to edit the scene on STYLY Studio, you should upload prefabs or FBX file separately.
