NumPreSelectedIndices

When we have no source locations and we need to track bone velocities due to bInheritBoneVelocity, we pre select a set of bones to use each frame.

Choose your operating system:

Windows

macOS

Linux

Syntax

int32 NumPreSelectedIndices

Remarks

When we have no source locations and we need to track bone velocities due to bInheritBoneVelocity, we pre select a set of bones to use each frame. This property determines how big the list is. Too low and the randomness of selection may suffer, too high and memory will be wasted.
