Mesh Space Additive Support

Nodes making use of mesh space additive deserve a special mention (e.g. Apply mesh space additive, AimOffset blendspace).

These nodes are implemented and will generally do something reasonable, but they do not implement mesh space additive blending of poses in crowd directly, doing so would incur too much of a performance cost. Instead, when a blend / blend space is encountered that uses mesh space additive the animations used by crowd are converted behind the scenes to a regular additive blend and the node using it is converted as well.

The results are typically plausible for the crowd and this avoids needing a second set of assets for crowd vs non-crowd ABP setups. There will however be differences in blend results, so something to be aware of. If the results of this automatic conversion aren’t good enough, it may be necessary to generate a second crowd-only set of animations and switch to it using a Crowd Animation Switch.
