I have this

ID3D10ShaderResourceView* myTexture = NULL;

ID3D10EffectShaderResourceVariable* g_pTextureReader = NULL;

ID3D10EffectTechnique* g_pTechnique1 = NULL;

ID3D10EffectTechnique* g_pTechnique2 = NULL;

now I do this

g_pTextureReader ->SetResource( myTexture );

g_pTechnique1->GetPassByIndex( 0 )->Apply( 0 );

g_pd3dDevice->Draw(1, 0);

g_pTechnique2->GetPassByIndex( 0 )->Apply( 0 );

g_pd3dDevice->Draw(1, 0);

then I want to render to "myTexture" renderTarget, so I need to unbound "myTexture" , to do that I do this

g_pTextureReader ->SetResource( NULL );

g_pTechnique1->GetPassByIndex( 0 )->Apply( 0 );

g_pTechnique2->GetPassByIndex( 0 )->Apply( 0 );

Is this last thing the way it is done normally?

don't know very well how the bound and unbound works, it looks like if I don't unbound them on every technique it has been bound to, the bound will be still there, so every time you want to render to a bound thing you have to remember in which technique it was bounded, and the only method I know to unbound texture is the "apply(0)" thing

anyone knows more?
