PeevishDave@grumpygamer @raysan5 never used raylib, but by taking a look at the code a quick way would be duplicate UpdateModelAnimation into UpdateModelAnimation(Model model, ModelAnimation animA, int frameA, ModelAnimation animB, int frameB, float blendValue), and do the same except the bone transform used is the interpolation using blendValue between the bone transforms A and B.
@grumpygamer @raysan5 To interp two matrices, you must extract Traslation, Rotation and Scale from both matrices. Then, linear interpolate Translation and Scale, while Spherical interpolate Rotation. Then, reconstruct the new matrix from TRS.
