Texture environment

Hi all,

I'm trying to integrate Texture environment in an MFC View:

myView->SetSurfaceDetail(V3d_TEX_ALL);
// we include a test for using texture environment
Handle(Graphic3d_StructureManager) aStrucMana = GetDocument()->GetAISContext()->MainPrsMgr()->StructureManager();

Handle_Graphic3d_TextureEnv tmpEnv = new Graphic3d_TextureEnv(aStrucMana, "env_medit.rgb");
myView->SetTextureEnv(tmpEnv);

But I don't see a difference when starting it. Do I have to change/modify still other structures (AIS objects for example) for seeing such effects??

Regards,

Patrik
