How do you use Orestes Iray HDRI Skydomes - Erupiter or other products by Orestes. All I find are files to load render settings. When I do a iRay preview all I see is a fuzzy varible colored sky. I don't see any planets or moons like what shows on the product page. Do you need to buy other products to get those celestial things? Do you need to load a skydome or something? And where would you find that? Thanks.

Did you check under Light Presets:Orestes Iray HDRI Skies ? I don't have the product to check. I'm just going by the readme.
Yes. Thank you for trying to help. I found the product under the light presets folder and there are only icons for loading the render settings. (Icons are marked RENDER.) I also found the product under the Product Folder in the Content library and the only icons that show are for loading the render settings. I also looked up the product to see if there was pdf or anything, but there was not.
I have several product by Orestes and everyone I've loaded has just given a gradient colored back ground. It's more random than that, but are no objects or images in the sky.
I don't have that one, but several others from Orestes Graphics. Those render settings load an environment dome for Iray, no need for other products for the celestial bits. Be sure you are in Dome and Scene for Environment mode. Even if you are not, when you load another one, it will set it up that way. Check to see if the Environment map is what you are expecting.
You need to rotate the HDRI until you get the part of it that shows the view(s) from the promo. Since they are usually large skies, you might need to get the camera to point the perfect way.
The option I usually do - is to render the exact scene without the HDRI dome included.
Environment Mode (Dome and Scene)
Draw Dome (Off)
------------------
Then I render the HDRI all alone in its own scene and pick all my favorite views and place those behind the render so I can have full control of the camera angle and the backdrop. I can also try a whole bunch of different ones and compare them. I only really do this with HDRIs that have a super-sweet spot.
And and before I forget, if it takes a long time to show the HDRI in Iray preview mode, you can use the filament preview mode. That will show you the HDRI.
I also own several HDRI products by Orestes, and none of them result in a "gradient coloured background". Are you using depth of field to blur the background? Please post a screenshot of your Environment and Camera settings.
I just opened the product and replicated your result.
Please try what I said and rotate the HDRI or move your camera.
When I use HDRI, it's helpful to go to Render Settings, Environment, Dome Rotation and adjust the rotation until you get the elements in the scene you need.
I don't own the product you mentioned, but I do own the quite a few of the Orestes Skydomes.
This one is Oblivion.
When loaded you see the first image, but then rotate the dome to the 0 setting and the planet is viewable.
Thanks for the help. When I use an HDRI, I click on the icon (has the word RENDER on it) to load it. Then I go to environment and tab and I rotate the dome by 30 degrees (Dome Rotation) and look for the best lighting for my seen. When I did this, I had already posed and framed my figure. Maybe that pointed the camera where it only picked up empty space. I'll do a test scene and just load the HDRI and see if I can find the cosmic elements.
I ended up rendering just the figure and then doing a composite.
I was not using DOF.
Thanks.
Von Hobo, I see in your second image that you didn't change the Dome Rotation setting. Did you change something else or just move the camera?
A lot of the time, it's not possible to get both the best lighting and best background image from an HDRI. In those cases, it's necessary to either supplement the HDRI lighting with other lighting assets, or else make a separate render pass like Griffin described. The tricky part is in making sure that the shadows make sense. It's also possible to do some other tricks in postwork, but that comes down to how familiar you are with your image editing software, and the kinds of features it has.
OK. I figured it out. I opened an empty scene and picked one of the Orestes HDRIs. All I saw was an empty sky in iRay. But at the bottom of the view port, I saw the universal selection tool...even though I had added nothing else to the scene. By it's position and angle, I rotated the view port down which turned the universe and brought the sky down and put the heavens into view. Thanks again.
