    I've bought this set and started experimenting with it. My renders so far need a lot more work but it's looking very interesting.

    If you're making more of these, some nebulas would be nice.

    Thanks peter, i'll keep it in mind.

    also a simple deep space starfield, with one star close enough to be a key light but not quite large enough to be in orbit, if that makes sense :)

    Is it totally wrong that I want to stay home and play with this tonight instead of going to the concert I'm supposed to be going too?  This would hit during a super busy weekend for me lol.  Maybe I can get to it tomorrow night....

    I would absolutely love more of these as well and would also be very interested in something for underwater.  Right now, if I want underwater I use 3Delight.

    Honestly making a 'playset' with more HDRIs and a few texture-mapped spheres would be ideal. Though I'm pretty sure getting my son to make some of those for me would be a piece of cake too. Hmm.... maybe I should put that on his homeschool curriculum....

    Rendering is never wrong Dragon, Never! I've had a suggestion about the underwater stuff, again i'll bare it in mind. It's a bit more tricky than the space ones since there's a volume effect that wont translate to the character in-engine without some trickery. I'll try a spot of magic when i have a window ;)

    That curriculum sounds better than the one i had at school. sad

    Love the look of these HDRs @KindredArts, I've been wanting something like this for a long time and for sure will be buying this weekend. I think people just need to keep in mind these don't work the way traditional HDRs work since they provide such low light, they are not a one-click lighting solution, you need to think of them more as mostly providing a pre-rendered 360 backdrop and use your own lights with them. I think I would just make an invisible mesh light with whatever HDR I was using in the scene, and then just boost that mesh light, then you get the same light on your subject as is in the scene, but greatly enhanced.

    OOOOOOoooooo, just thought of one more...

    simple starfield, motion blurred/stretched stars, redshift/blueshift

    WARP SPEED!

    This is sort of true, in fact it's something i didn't even consider whilst doing them the first time around, which meant pulling them and completely overhauling each one. They worked great as backdrops, but due to their nature, they didn't really emit much light. That's why in most of them you'll see a bright white sun somewhere in the scene, i added them to have some sort of directional light. They're never going to be as bright as a natural day-lit HDRI, but i've tried my best to add as much emitted light as possible without sacrificing visual fidelity or believability. As you said, there is of course still the option of adding fill/key lights to further boost your subject.

    I getcha', Like starcitizen/elite. I have some theories on how to do it, we'll see how it pans out :)

    We didn't have computers when I was at school. We had to write on paper with pens! Our school was so traditional they didn't allow biros, it had to be fountain pens .... sorry, I'll calm down now smiley

    I have a question,

    say I want to use my custom backdrop (Starfield+ nebulae) and place my ship on top of that background separately -in photoshop.

    Could I, in Daz, use your HDRI for lighting up my props and render with the Dome/Sky-box off (.PNG File)?

    And get my ship/satellite/space station with your HDRI powered light and shadow as a render?

    ---------------

    To explain, I never use the included skybox/dome. I always add my own space and sky.

    Can I ONLY use your HDRI space for lighting (or minimal shadow casting) my props?

    I was sure you could, but just tried it - go to Environemnt> Dome in the Render Settings dialog and choose Draw Dome: Off

    But as you'll see, you then do not get any redflections

    Yes you can use these without them showing (just for lighting) then save out the image as a png to use your own background.

    I did it here rendered the image with the sky dome turned off and then rendered the sky dome and composed in photoshop, helped with the placment of the sun.

    I see this has already been answered. I would like to add though - if you're using the Hdrs for lighting only, you may want to use lower exposures. I've tried my best to inject as much light as possible, but space is .. well, a bit dark. Some of the scene's have a high amount of light contrast so you may have to account for that depending on the look you want to achieve. I'm always around if you need a hand with anything.

    Maybe it would be nice to have a preset or preload option with tweaks made, so that users can see the possibilities out of the box?

  • I'm playing around with using these in reality/luxrender and I'll post some results when it bakes a bit.  The only drawback is getting a background since lux won't render an hdri on a dome.

    Couldn't you load the HDRI into the reality sphere which has it's opwn HDRI?

    DOH I completely forgot about that.  Its been a while since I used reality/lux.

    What sort of tweaks are you looking for? The presets load environment and tonemapping settings. Do you mean camera settings?

    Just a quick test I threw together with some foreground asteroids to give it some depth. Its a little shaky because I did a low frame rate. Below is at only 400 iterations, rendering took only 15 seconds a frame with dual 980tis. Perfect for animation. At first I tried extra lighting, but it wasn't necessary, plenty of light with this particualr HDR, some of the other included ones may need it, but this one was ready to go as is. Just minor tweaking of the tone mapping.

    Thanks, you made it very easy by creating such beautiful HDRs!

    If you're not rendering with the dome on, why would you buy this? You would be just as well off using the default Studio HDRI and tone mapping for the exposure you want.

    I render with the Dome off for a variety of reasons and nearly always use a HDRI;  the lighting results will not be the same by using the default HDRI and just altering the tone mapping, light direction colour are all different and will give different results.

  • Im still having alot of trouble with this product. If I try to render with any of the earth presets i get a black screen. If I try to render any of the alien planets, I get a black screen with specs of color in it. Im using a default camera and adjusting both focal length and frame width and I get no change to the render...

    Turn the camera so that it's facing the left-back corner as indicated by the directional cube.

    What directional cube?

  • Ohhh, there it is. I still dont see a directional cube but I can see the earth now. This product needs camera presets. It should not be that difficult to find what youre looking for.
