Vray crop/place hdri only on activeshade???

[miguelsantos]

Hi, again I have a question, this time I'm getting trouble with vray hdri map, I'm trying to render a hemispherical sky, with a texture of the sky with the resolution of 8000x2000 (hemisphere) but, I only get the hemisfere using the crop/place option in vray hdri map, but why this function only works in the activesahde mode? I'm using the same configuration, only change from activesahde to renderprotuction and the hemisphere turns on a full sphere., I know that I can trasform the image on a full sphere map by adding the "ground" but I just belive that i can use only the sky as a map. Anybody knows what is happening? here some images do better understand:
