Collision Painting

The Collision Paint tool is used to "label" objects or parts of objects to change how they interact with characters that collide with it.

How To Use

The Collision Paint window can be accessed in Edit Mode by navigating in the menu bar to Windows -> Collision Paint.

Collision Paint window

• View the collision by checking View Collision
• To paint whatever the cursor hovers over press B
• To paint the whole object check Per-object
• To paint per-triangle check per-triangle
  • To only paint the hovered triangle check Don't Spread
  • To paint the hovered triangle and adjacent triangles with the same orientation check Spread across flat surfaces
  • To spread to Triangles with similar orientation on the same object check Spread across similar normals
    • The Range decides how similar the normals of each triangle need to be to spread, 1 spreads almost nothing, -1 spreads to everything
• The Load button loads any currently existing collision paint.
• The Save button saves the current collision paint.

Labels

The label checked in the lower box will be applied to the triangles by painting. The painted surfaces will indicate its parameter with a specific color when View Collision is checked. Each label's color is written between parentheses below. TODO: add a better way to see the colors. maybe like this ?

Floor

TODO: add and confirm the effects

• Walkable: (Green)
• Balance: (Light-Green)
• Slide: (Cyan)

Wall

• Wallrun: (Red) Allows wall running on those triangles if they're steep enough.
• No wallrun: (Orange) Won't allow wall running on those triangles.
• Ledge: (Pink)
• Ragdoll: (Blue) Character will ragdoll.
• Ragdoll-death: (Blue) Character will die.

Ceiling

TODO: add and confirm the effects

• Ceiling: (Blue)

Unlabled

• Clear: (No color) Resets to the default collision behavior which is based on he triangles normal.
• No climb: (Grey) Has default collision behavior except that the edges can't be grabbed.
  • You can paint the 'no-climp' label to all unlabled triangles by clicking the Apply 'no climb' to all unlabled surfaces button
