•Problem faced– Change in Bone Count or Hierarchy– Change in Character’s Proportion– Change in Character’s Overall Dimensions– Animator’s file may be initial rough model
•So, animator has to– Save all the animations one-by-one– Load these animation files into the final model
Animation

•Batch Save and Load Animations
Batch save ‘bip files’ from max files Batch load ‘bip files’ on finalized
model
Animation

•Process for our earlier MascotCapsule v3 rendering engine in our game development pipeline– All animations 1st frame be positioned at x = 0 & y = 0– Insert a new 1st frame common for all animations– Export this max file to fbx format (This process is to save data)– Import the fbx file– Change the fps as required for the target phone– Adjust the ‘main key poses’ – which may be lost in fps reduction– Collapse the trajectory to 1 key per frame– Place BAC axis in (0,0,0) to take care of y-z axis and origin.– At last, export the file to bac and tra
Exporting

• Approx. export time per animation manually = 4 minutes(Ignoring the potential human errors)

• Approx. export time per animation using script = 8 seconds(Plus gives detailed report witherrors and warnings)
