You mean an actual sky dome model? You can try aplying the Iray Uber base shader's Emission prset, then assign the skydome's map to Emission Colour.
I mean a sky dome that comes in a set like secluded shoreline 21889-they do not come already set up like you said-in the set there are no icons other than the it should be already to go no?
or in predatons essetial lights and sies sku 21889
they are sky domes that should be working once the scene opens, cant figure out why would preview black , us novices will get stuck
can you help me pout so that can function properly
In Iray there is not option to have objects not cast shadows, so the dome blocks al external light (Sunb/Sky, HDRI environment, distant lights). The steps I gave above should allow you to use the dome, or you can hide/delete it and use some other solution.
But you can use a dome with transparency maps, such as having a cloud black and gray scale trans map.

Flipmode has this tutorial about how to use his older skyboxes in Iray renders: https://flipmode3d.com/converting-3delight-skies-to-iray/
It may help with the FirstBastion and Predatron ones too.
I just answered a question from the OP in PM. These are pre iray products with literal physical skydomes that are blocking the HDRI light in Iray.
copy paste of my PM respense.
Hello, that particular product is older (SKU:21889 ), and was specifically designed for the 3Delight renderer in DazStudio and will not work without significant tweaks in Iray. If you select the Render Settings tab, and change the render engine from Nvidia Iray to 3Delight, you will get the promo images.
If you wish to render exclusively in iray, you need to delete the included physical skydome which is basically blocking all the light in the scene (hence the reason the preview is black) and use one of the many HDR skies products available in the store. Unfortunately the textures are optimized for 3Delight and will need to be tweaked for use in Iray. It is certainly something experienced user can adjust but it is an involved process.
It may be best to return the product and get a refund.
Generally products earlier than 25000 are pre iray, and generally designed for 3Delight rendering. If a product description does not specifically say iray materials settings/presets, assume the product does not have iray compatibility.
Hope this helps.

Thanks for everyones help-
You are right cridgit i love the set, best ocean/island one i have bought, the rocks are what drew me to it, wouldnt return it, wanted to get the feeeling of Jason and the Argonauts (the original) thats why i most got it, but it is great all around!
-the sky dome i did get to work fo9loowing the tips I got (thnaks again), maybe the sky is not as rich the color but still works! noiw i cqan use all predatons sky images i bought along with it! ive been wanting to uyse a sky dome forever a si always have a plane with ja sky so i can see the priview render everytime i choose nvdia view-dont what to wait to bring it into gimp to add background image
Thank you cridgit for the kind words and I'm happy to hear vshyman has figured a way to put the set to good use.
You are right. I had not tried that set out in a while, so I spent 10 minutes with it, and used the Maui HDR sky that is included with the DazStudio bundle download. Very preliminary but it is certainly still usable. Thank you for the counter suggestion.
