Execution Code:

Code: [Select]

  if(!effect) return; //later we'll put in some placeholder image, but for now just fail

  _sblock->Apply(); 
  SETEFFECTPARAM("move", COP(cDirectX)->getCamera()->x/_xreduct);
 
  UINT iPassCount;
  //effect->Begin(&iPassCount,D3DXFX_DONOTSAVESAMPLERSTATE);
  effect->Begin(&iPassCount,0);

    COP(cDirectX)->getDevice()->SetRenderTarget(0, rendersurface);
    //COP(cDirectX)->getDevice()->SetTexture(0, _bgtex->tex);
    effect->BeginPass(0);
    COP(cDirectX)->DrawFullScreenQuad(0.0f,0.0f,1.0f,1.0f);
    effect->EndPass();

  effect->End();
  COP(cDirectX)->getDevice()->SetRenderTarget(0, COP(cDirectX)->_curframe); //reset our rendertarget

WHY IS THIS NOT WORKING?!

(i'm also posting this on gamedev.net since they know more about this stuff)

Ok, generating mipmaps for my images would be a good idea...

solved.
