Iray Opacity Map reversed?

3dOutlaw

I was making a makeup map on a geoshell, and when rendering in Iray, if I set the map to white on black, it looks good in viewport, but is oppsite in render.  (and vice versa, black on white looks wrong in viewport, but correct in render)  I also had similar issues with LIE and PNG's.

Is this a known issue or is it just me?

OK, maybe I figured it out...I was trying to drop a PNG right on a colored diffuse, and it did not like that.

I kept at it, and made the colored diffuse a layer under the PNG (in the LIE), and then changed the main diffuse to white....it worked.
