How it works
LINEAR and STEP use one output element per keyframe. CUBICSPLINE uses three. Morph weights multiply this count by the number of targets.
Three translation keys need 3 VEC3 outputs for LINEAR or 9 for CUBICSPLINE.
Limits
Checks counts and strictly increasing nonnegative times. It does not inspect the output values or fully validate interpolation.
