I am planning to implement batch node animation using set of PNGs (instead of using a spritesheet generated from external tool) by the following way:-
i) Generate animation from the PNG set.
ii) Generate a texture which is combination of all the PNG to be used in the animation.
iii) Use the texture generated in step (ii) to generate batch node.
Please tell what will be the disadvantages of using this approach vs the approach of using spritesheet generated by an external tool.
