Console commands
stat Chaos
p.Chaos.DebugDraw.Enabled 1
- Must be called so other commands work
p.Chaos.Solver.DebugDrawShapes 1
(engine will callFPBDRigidsSolver::DebugDrawShapes
each frame)- Red: Not simulated, Static
- Blue: Not simulated, Movable
- Yellow: Simulated (Active)
- Gray: Simulated (Sleeping)
p.Chaos.DebugDraw.MaxLines
(default to 20000)

Draw
Chaos has a special helper for drawing, which is thread safe (under the hood it uses the global draw helpers functions, see DebugDrawChaosCommand
).
See Chaos::FDebugDrawQueue
and UChaosDebugDrawComponent
.
Example: Chaos::FDebugDrawQueue::GetInstance().DrawDebugSphere(ParticlePoint, 4, 32, FColor::Yellow);
For p.Chaos.Solver.DebugDrawShapes
the drawing root path is FPBDRigidsSolver::PostTickDebugDraw
→ FChaosDDParticle::DrawShapes
.
See also FChaosDDParticleShape::Draw
.
FChaosDDParticleShape::GetRenderColor
is used if no color is given (default case for engine) and it has multiple checks to know what color to use, most of the case this falls to reading to use FChaosDebugDrawColorsByState::GetColorFromState
on DebugDraw::FChaosDebugDrawSettings
.
