Assertion error in animation library: ID3DXAnimationController::RegisterAnimationOutput: Number of matrices registered is equal to the max number set at creation time.

Question

When I replace the tiny_anim.x animation file with another one in the DirectX multianimation demo I get the following error:

Assertion failure! (s:\gfx_sdknovember08\windows\directx\dxg\d3d11\d3dx9\anim\loadxh.cpp 1392): D3DXFrameNumNamedMatrices(pframeRoot) == plc->cNamedMatrices D3DX: ID3DXAnimationController::RegisterAnimationOutput: Number of matrices registered is equal to the max number set at creation time.

This is only with some exported models and not with all.

What could e causing this problem?

You're using the November 2008 SDK? Try using the March 2009 SDK (or August 2009 SDK if its out by the time you read this).
