I noticed that if I export my blender project as a obj-file I have the option to toggle "Export Animation" which will make alot of files, one for each frame.
I wanted to use the Collada (.dae) format to export my animations. Problem is, when I load my Collada file it says that NumAnimations == 0!
1) Why does a file that is supposed to store animation say 0 animation?
2) When I do get it to work, how to I swap between frames in Assimp?
1) Animation import should work, your problem is probably the export. Have you tried reading through your collada file? Watch for <library_animations> and the like.
2) Assimp has no notion of frames. aiAnimation consists of multiple channels (aiNodeAnim) which define transformations (keyframes) for nodes at specific ticks/time. To compute all transformations one needs to interpolate the correct keyframes depending on the current playback time and mTicksPerSecond of aiAnimation.
