Grab the prototype textures
For blocking out the level
These texture are a grid pattern
So we get an idea of how big things are
To prepare the prototype material texture
Double-Click the GrayMaterial.tres file in FileSystem
Quick Load the new texture
Create a New Scene with Node3D as root
Add a CSGBox3D and rename to Room
Disble Shadows on the DirectionalLight3D
Set the dimensions of the room
They will become rooms when we flip their faces
We will combine CSGBoxes to create multiple rooms and corridors between them
Add a CSGCombiner3D as a child of Room
Leave the operation mode as Union
As a child of CSGCombiner3D
Set the dimensions of the room
And corridors of your own
