Hi Folks,

I don't get any animations out of this code, the model is confirmed to be animated in mesh viewer.

Please help

You cannot have 100 x float4x4, maximum is 64

float4x4 FinalTransforms[100];

Hi Belfegor,

I have brought it down to 60 to no avail.

It is still not animating.

Any further suggestions?

Thanks

Jack

the time value is to small

+1 what ankhd said, also enable d3d debug runtime to see debug messages and check all functions that return HRESULT for error.

The PIX program suddenly stops working. I run the experiment, see the output and no debug pane comes out.

So I need to debug it by hand. I can see the m_pBoneMatrices change every time, so it must be in the shader

Any suggestions that why the shader fails?

Thanks

Jack
