You need to export them from your script.

Let’s turn github into Instagram. Every snippet of code has to be attached to a picture or video…

Regarding 3d models, you can:

• use spheres and cubes as placeholders, there is no need to create 3d models as long as you don’t have a game yet.
• you can download models for free from various websites
• you can make your own 3d models with blender ( If you don’t know how to do that yet, you will have to spend some time learning about blender first. Checkout blenderguru)

Since you ask for the easiest solution, just use CSGMeshes for your maze and a cube or sphere mesh for your enemies.
