braindigitalis, collada supports animation, too. The problem is that I don't know how to load it into OpenGL.
lawnjelly, I already have the animation data from Blender, i have the file, I just don't have any idea how to parse it.
And I cant use vertex tweening, I need to use skeletal animation, because this is how I make my animations in Blender.
'Having a file' means nothing *unless* you can parse it. A quick google of collada suggests it may be overly difficult to parse.
Hint: Skeletal animation is often used to create the data for vertex tweening.
