HDRI Dispaly in Viewport

[hkalmus]

Using MAX 2013, VRay 1.5, when loading an hdri file through VRay hdri, under Viewport Configuration I check use environment background but there is no longer a "display background in viewport" button. I assume I am missing something obvious. How do I get the image to display - where did this button go? Thanks Harold

Did you click on "Apply to Active View"? or just clicked "OK"?

I did click on apply to active view...The viewport does turn black but the map does not display, and it's not a matter of the multiplier, I've tried down to .1 an up to 200.
When I load the hdr map through the bitmap choice instead of VRay HDRI button, it will display in the viewport - but then I have no controls available.

It is not supported in Version 1.5 - newer versions 2.x and 3.x beta already have support on that matter.
