When use Blender?

• If you need to create 3D assets of your own.
• If you want to add a new classroom/ level, change the building,…

Why use Blender?

• it's a modern, open-source, free-to-use 3D Modeling and Animation program that utilizes similar asset pipelines to programs such as Maya and 3DSMax (which are not open-source and free-to-use).

How to use Blender?

• We'll not create a specific tutorial, there are great ones online, check for example Blender Guru

⚠️ But, if you use Blender, please follow this process to import the Blender models into our Unity project! As .blend files require Blender to be installed, we decided to not use them directly in Unity. But there are two options to import Blender files in Unity.

⚠️ We are not importing .blend files directly into Unity. ⚠️ Instead:

Export a .fbx file from Blender and import it into Unity

• To export an fbx file, go to File > Export > FBX (.fbx).
• Check, that you are not exporting anything else (camera, lights, etc). We only need the mesh in object types
• Take care: Unity and Blender use different coordinate systems (right handed vs. left handed = Z and Y are flipped). Because of this enable "apply transform" to make the transform coordinates work for Unity.
• export the model and place it in the assets folder (Assets/Models), now you can drag the object in your scene
• also add the .blend file in the assets folder
