[UE3] Direct3D Model Occlusion Exploit

Ever had models behind walls, but you couldn't see them because UE3 occluded them?
 
Never fear!
 
HRESULT WINAPI new_CreateQuery(LPDIRECT3DDEVICE9 pDevice, D3DQUERYTYPE Type,IDirect3DQuery9** ppQuery)
{
 
if( Type == D3DQUERYTYPE_OCCLUSION )
{
Type = D3DQUERYTYPE_TIMESTAMP;
}
 
return gOriginalDevice.CreateQuery( pDevice, Type, ppQuery );
}
 
 
 
this will return a non-zero value for the number of pixels visible from your camera's position, so, they will always be drawn now.
 
I do not know if this has a great performance hit but in case it does, just check the returnaddress (or returnaddress of the returnaddress )
