Reverse loop animation

[Noiecity]

Irrlicht allows me to activate the animation loop correctly, but what if my model would like to repeat the loop first forward, then backward? Example in frames:
1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 6 -> 5 ->4 ->3 ->2 ->1->2->3... etc
What solution would I have? I mean, I'm finishing building the models that I plan to upload to the forum, I will upload them in md2 format, but this question arose when it comes to animate them, in terms of size is more advantageous to make irrlicht reverse the loop at the end of the animation ... or else I would have to create it inverted from the model and increase the size of the model itself.



It would be great if md2 type animations could have an overloaded value of true or false for loop reverse animation, it would be useful for many animations, and for others it would not.
Like "node->setMD2Animation(scene::EMAT_STAND, TRUE);"

You could add more animation frames and second part has the reverse.
Otherwise you probably have to do your own loop - so play once - wait for end - play reverse - wait for end - repeat.

Yes, the first is a viable option, it was the option I was going to choose if there was no separate solution, there is a program I have called QME, it allows me to separate the frames and name them in a .md2 file.... quite useful since irrlicht literally has support for internal animation names in md2 format.
