How to Show Iray Sky Domes

Iray sky domes seems like a contradiction. I bought some 3rd party Iray HDRI night skies. But they just rendered black. I had to turn off Sky Dome visibilty in Parameters to have the Iray lighting acess my scene, which makes the Iray sky dome useless. After you have chosen say a night sky SkyBox or Skydome  Iray HDRI 3rd party product for your Environmental Map

Chose "Dome and Scene"

However, I began to realize the Sky Dome (or Sky Box) of third party products were "finite" as contrasted with the Daz Infinite sphere. Aha!

So make Dome mode "Finite"

Choose On "Draw Dome" (I didnt need ground)

Now the option I have never seen mentioned anywhere, in searchs, or tutorial  that makes it work: "Visualize Finite Dome" which of course you don't see if you haven't selected Dome Mode:Finite!

Attached is the Render Setting menu as I set it up for a quick example.

I have finally been able to render a moody night sky! Ok, it's not awesome, but this is a straight render using an Orestes product. I can add other lighting features. The important thing is I now have the ambience and tunable background. Hope that helps!

    A modelled dome will block light - sets with those are geenrally made for 3Delight.

    Visualize Finite Dome only colours the dome with various colours so that you can position it, it isn't used for rendering and should be turned off.

    One of the products I recently bought is Orestes Iray HDRI Skydomes - Winter Moon by Orestes. which I used one of the HDRI's in my posted example Iray render, but such as the Enchanted Forest, all I can do is turn off the visibilty of that 3Delight skydome ---which you had helped me with a while back!

    @Fishtales, thank you for the info about the Visualize Finite Dome. Apparently, one uses this tool with the Iray View. Haven't tried that yet, but if that makes the positioning of the HDRI image within the View  easier, that will save guessing time.

    Are yopu saying it loaded a modelled dome, or just that there was a dome in the scene to start with?

    If there is a skydome loaded with any scene then click on it, move the mouse over the Diffuse map and see what image is being used. Go to the Environment Pane and click on the Environment Map and add that image there. Delete the skydome and the background will show up in Iray as it is now on the Iray Dome. If it is a good enough image it will also give you some ambient lighting.
