I have ported a CPP Model Animation program to C# using Opentk and Assimp. The model displays correctly, texture etc… when I apply the animation, th emodel seems to animate correctly, but the model is totlaly distorted.

I have printed and compared almost everything between the CPP program and the C# program. Vertices, bones, weights, interpolations, shaders, etc. All data matches except the interpolations because of timing differences. The calculations are the same. A single Mesh DAE file.
