Summary:

Animation controllers do not blend scale correctly

Impact:

Issue needs to be worked around, requires more time in production and unnecessary complexity

Repro Steps:

1. Load the attached resource and behavior packs into MC
2. Spawn the "Scale Blending" entity using a spawn egg

Observed Results:

The scale of the entity transitions between two states. On each transition, the scale of the entity increases, reaches a peak and then decreases until it reaches the next state.

Expected Results:

The animation should transition linearly between the two scales (see attached graphic)

Screenshots/Videos attached: Yes

Regression Builds:

Never worked
