Hi.
i want to make a 3d animation and put in in unity as a character do i use 3Ds MAX?
and if i do how to add it to unity??
3ds Max is an excellent choice for creating character animation; so is Maya. Probably more people use Maya for character animation, but 3ds Max actually has more rigging options. You can create rigs manually, use Character Animation Toolkit (CAT), or Biped. Biped is a bit older and has some issues that I prefer not to deal with, but a lot of people still use it and it is a viable option. CAT has much more flexibility and stability in my opinion. It has all of the advantages of Biped, but none of the disadvantages.
You add an animated character (or just the animation) by exporting to FBX format, which is the native format for Unity.
