As the topic says I'm trying to use my own meshes in the DX SDK sample multianimation.

The mesh appears for one frame, then it disappears. It appears to be because of

D3DXMatrixMultiply( &pFrame->TransformationMatrix,
&pFrame->TransformationMatrix,
pmxBase );

in AnimationInstance.cpp

As I read in a thread here it doesn't reset to the original value but it multiplies by itself so if the value is (0,0,2) then it gets (0,0,4) (0,0,8) (0,0,16) and so on

How can I adjust this function to work properly with my mesh?

In the thread I read the author said he had to inverse the multiplication to undo the changes but how?

The search function isn't working now so I cant find the thread, but I'll update this post as soon as I've found it.

Edit: This is the thread i mentioned
http://www.gamedev.net/topic/501879-multianimation-sample-seems-to-be-geared-to-only-loading-tiny/

I would appreciate if somebody could help me.

Thanks, Ritti
