OK, got myslef MR from alias site. Its great, I'm learning it, but, trying to figure the way that mental can use hdri. I went thru some tutorilas on how you place hdri into ambient color of the shader and light the scene with that. Well that works but, it doesnt lite the scene as a real 32/42 bit hdri. In other words there are only white and black points, no RGB values. So, if any of you got suggestions please share.
And its for maya btw.
