Hello, I'm trying to do skinning with SlimDX but I don't can't make it work. The function UpdateSkinnedMesh takes a bone transformation matrix as its first parameter but I don't understand why is like that since in DirectX it takes an array with all the bones transformation matrices. What I did was: - Get a bone from the hierarchy - Rotate it - Update combined bone Matrices - calculate transformation matrices multiplying each offset matrix by the corresponding combined bone matrix. - calculate the inverse transpose matrix for the UpdateSkinnedMesh function and now I tried calling UpdateSkinnedMesh twice (I have 2 bones), once for each transformation matrix, but this gives me strange results. It rotates the wrong bone. Any ideas? Thank you in advance.
