Hi @digib_rit
What might be going wrong here is the Unity scene you are trying to import to Arkio contains extremely distorted/scaled cube meshes. The Arkio Unity exporter only supports exporting prefabs and game objects that are uniform-scaled.
As Unity is a tool to compile game levels from geometry created by loading meshes from 3D modeling tools like Blender, SketchUp or plugins for Unity like Probuilder.
You can best learn more about these mesh modeling tools first if you are new to level design as techniques like UV mapping and mesh optimization are required if you want to get the best out of your game engine.
Arkio’s Unity plugin can best can be used to load all your Unity scene meshes to Arkio that can then be moved scaled and updated in Arkio and later exported and updated back to Unity (uniformly scaled). You can try this workflow by loading some example scenes from the Unity Asset Store to Arkio instead of your current scene.
