Hi people.
in this moment I'm trying to animate a simple model In OpenGl Using Fbx SDK I can get the Spaces Points of the model and the initial global transformation for see the model correctly in Opengl this is the model in blender.
When I import the model in Opengl Using Shader Program with bones and weights looks like.
Load the model is no the problem, the model has 4 bones each bone has 1 Weight and I get the initial matrix of each bone using
fbxCluster = Skin.GetCluster(j)lMatrix = FbxAMatrix()lMatrix = fbxCluster.GetTransformMatrix(lMatrix)
When I load this four matrices in the shader program I can see the model like the previus picture. When I'm going to animated the model I used the inverse of the BindPose, I get the Inverse Bind Pose Using
lMatrix = FbxAMatrix()lMatrix = fbxCluster.GetTransformMatrix(lMatrix)
linkMatrix = FbxAMatrix()linkMatrix = fbxCluster.GetTransformLinkMatrix(linkMatrix)BindPose = linkMatrix.Inverse() * lMatrix
Ahm I get the current Matrix of each bone Using
TransforMatrix = b.EvaluateGlobalTransform(CurrenTime, FbxNode.eSourcePivot, False, False)
Ahm the final matrix is
CurrentMatrix = BindPose * TransforMatrix
Ahmm this is the result see the animation is Fbx autodesk Viewer and see in my program.

here in my OpenGl program.

You can see the bones are rotated in Global Space, ahm Works Wrong, I have been trying to do this since 2 months ago, I don't know what to do please help
