: This was a critical component of the SDK, allowing developers to run a debug view alongside their game to inspect physics scenes in real-time.
A notorious bug: If a ragdoll's bones stretched beyond a threshold (e.g., character clipping through geometry), the inverse kinematics solver in hkpRagdollConstraint would produce NaNs (Not a Number). The SDK lacked robust NaN propagation; instead, it would crash deep inside the hkMath::sqrt SSE intrinsic. The fix: inserting hkMath::isFinite() checks before every constraint solve. havok sdk 2010 2.0-r1
