Loading FX instance in D3DXLoadMeshFromX
Author
The 6th parameter of D3DXLoadMeshFromX ( LPD3DXBUFFER* ppEffectInstances ) is supposed to return an array of effect instances specified in X file. And it does, filling D3DXEFFECTINSTANCE structure. But for some reason or other, it does NOT fill its (LPSTR pEffectFilename) field, though I can see that the effects file name IS specified in X file. This sort of troubles me, for it's the only field I really need. Any suggestions? Thank you.

Sorry, I forgot to show what I'm doing:
LPD3DXBUFFER effectInstance = NULL;
if( FAILED( hr = D3DXLoadMeshFromX( strPath, D3DXMESH_SYSTEMMEM, pd3dDevice,
&pAdjacencyBuffer, &pMtrlBuffer, &effectInstance,
&m_dwNumMaterials, &m_pSysMemMesh ) ) )
{
return hr;
}
D3DXEFFECTINSTANCE* effect =
(D3DXEFFECTINSTANCE*)effectInstance->GetBufferPointer();
strcpy( m_effectFileName, effect->pEffectFilename );
And I always receive NULL in effect->pEffectFilename, though other fields of D3DXEFFECTINSTANCE contain valid information.

{

I remember something similar happened to me.
It should return an array of instances but the first item in the array always had no filename associated with it. So I always start at "1"... it works but I never understood why this happened. Maybe my maya exporter was buggy.

Where and how exactly in the X file can the effect instance be specified? It would be cool for me to know that as currently I keep a track of various effect files for the different meshes I load in my project.

Panda exporter includes an EffectInstance template in the generated X if the corresponding checkbox is set.
