Start with what you are trying to make. Every page opens with the answer, a working example, and when you would reach for it.
Do something
Make shapes
Everything starts as a shape.
Change shapes
A primitive gets you the rough thing.
Combine and cut
Most things you build are several shapes treated as one.
Repeat things
A hundred rocks, a ring of pillars, a fence that keeps going.
Vary copies
Scatter twenty rocks and they are twenty of the same rock.
Place things
Getting a thing to sit on another thing sounds like the easy part and is where
Break things apart
Rubble, debris, a smashed crate, a wall with a hole blown in it.
Select parts of a mesh
Sometimes you want to change part of a shape and leave the rest alone.
Materials and appearance
Colour is the cheapest way to make something look finished.
Make things move
A spinning pickup, a bobbing gem, a door that swings, dust drifting.
Build reusable systems
The second time you build the same thing, stop.
Fix a problem
- My animation does not move
- My bend just tilted it
- My colour came out flat
- My copies are all the same
- My copies of a part do not match
- My cut did nothing
- My part is floating or sunk
- My selection does nothing
- My shape is the wrong size
- My shatter barely moved
