VRAY RT and VrayLightDome issue

[VISUALMAN_TOKYO]

In VrayRT I can't get light nor reflections from a vrayLightDome using an HDR image file connected to it's texture parameter. Is there something I may have missed to make it work? The scene renders but it is all black. It works well without texture and using just the color parameter.

Does it work with the production renderer with the same setup (my guess is that it won't work)?
RT CPU or RT GPU?
What version of V-Ray are you using?

I am using RT GPU (CPU didn't worked neither) and with production renderer worked fine. However somehow is working fine today! Not sure what was the cause, could it be the graphic card memory issue? Version is 3.10.01 on maya 2016.
