Geometry

(Most of this should be elaborated on at some point.)

N-gons

• They’re fine as long as they’re at and won’t be animated.

Triangulating

• Don’t triangulate your models.

Inverted normals

• By inverting the normals of a model you can achieve an interesting pseudo transparency effect.

• It’s not realistic but we’re not aiming for realism.

Double sided

• Many thin objects such as paper, leaves or cloth don’t need to have proper thickness, but for performance the engine does backface culling, where faces that are “backwards” aren’t rendered.

• This can be avoided by selecting the mesh, duplicating and then inverting the normals.

Pivot

• Always at the center (XZ) and base (Y) of the object.

Modeling with NURBS

• Cables and wires, but also some round but geometric objects like the plastic “cup” chair.

Cell fracture

• To shatter objects for ingame destruction. Takes some setup.
