PASS model loaded: 167 joints, 77 simulated spring bones in 16 chains {"bones":167,"springBones":77,"chains":16}
PASS clips idle/walk/run/spin_jump present idle,run,spin_jump,walk
PASS canvas shows the textured model (colour variety, red cloth and gold armour pixels) {"colours":239,"red":158,"gold":62}
