I see,
Most of that went completely over my head. Luxus does seem a bit complicated for that kind of thing. I think I'd rather bung up a skydome and an outoor light set for 3DL, I think I might even have some somewhere.
Thanks for explaining anyway
CHEERS!
It's actually pretty simple when you think about it. The null turns into your environment light, and the distant light becomes your sunlight. With the environment map in place, you're automatically getting that lovely skydome you need.
The biggest benefit is that because it uses HDR, you get lovely realistic reflections which combine with any other light your scene provides. It adds a lovely sense of immersion which can be difficult to achieve with regular skydomes.
Yeah, I think the problem is that I'm not thinking about it, I'm devoting my mental energies to other things right now and mustn't drift if I'm to get anything done. Maybe, when I've got everything else out of the way, I'll come back to this and it'll make perfect sense.
I wish I was one of those that could keep several interests going at once, but I'm just not. If I try to then I end up with loads of unfinished stuff hanging around, which isn't terribly satisfying.
CHEERS!
I agree but then Herold is one of those who tweaks everything so I guess to them its no biggie I dont care about post working stuff in as long as one gets the end result..
So that's the original LDP. I wonder why Val hasn't done LDP 3 yet!?
CHEERS!
'parently there won't be any
Pity,
I wonder if someone else will come up with something. I guess we'll just have to see....
When I can get back into 3D full time again there is so much I want to do.
CHEERS!
The majority of the time I also postwork in sky backgrounds as it's easier to get the final result I want. That being said, I do like to tinker and experiment, and as a result I've created several preset IBL's designed for use in Luxus. I'm considering posting the set up on ShareCG as a free download. They're pretty simple to work with as you just click to place it into the world and rotate the sphere to position the light appropriately.
I've designed them to be similar to UE in that you have a sphere which is invisible in the final render, which allows you to position the light correctly. They're set to the correct intensity for the environment map as well, so it's as simple as adding it in and rendering. The only thing preventing me from uploading it is that I want to include metadata with it, so that it appears in the smart content tab for easier handling.
Would it work in Reality? Don't take it as bad feedbak its cool you can do that im just too lazy LOL I just like to keep it simple since I produce mass render stories
I still haven't figured out how to save a Reality preset since everything has to go through the Reality window. There are certainly ways to mimic the effects, but making them available to other users as an easy-to-assemble preset is something I haven't figured out yet.
Well, isn't this annoying. I got the file all ready for uploading, and even provided a nice metadata installer for it. Unfortunately, the file size due to the HDR images is a whopping 222Mb in size. Sadly, this is far and beyond the limit provided by ShareCG so I'll need an alternative upload option. I did try uploading it to my DeviantArt stash, but even that failed miserably. For some reason, DA doesn't like the file, and refuses to even start uploading it.
I'll give it another try a bit later.
There are also HDR sets available for rendering with 3Delight in DazStudio.
Below is a render of P3Design's Leia for Genesis together with Shuttlestar.
Light and environment were provided by HDR Pro Sets Urban Recreation
http://www.daz3d.com/urban-recreation
Gamma was set to 2.2 (new option in Daz Studio 4.6).
Rendering Time: 10 minutes 43.20 seconds
By choosing the appropriate HDR you can have any kind of lighting you want in the scene. It's all relative. In 3Delight, you'd have to mimic the settings by altering the light positions and colours. The alternative in 3DL is to use UberEnvironment, of course, but this effectively turns your HDR map into an image-based light which is pretty much the same effect you're trying to achieve in Luxrender. The difference here is that in Luxrender, the light is genuinely light rather than a faked shader-based solution, so you get all of those wonderful colours behaving as they would in the real world.
Here's a simple seven-step solution to getting an HDR map into Luxrender. Note that this uses Luxus, not Reality. I've so far been unable to reproduce the same results in Reality yet, but I'll update as soon as I figure it out.
1) Create a distant light and position it where your sun would be (I chose a distant light because you can 'aim' it).
2) With the parameters tab selected, click the options button where the Luxus conversions tools are hiding. Select 'Luxus - Luxrender Light' and convert it into a Sun. No sky, just sun.
3) Create a new null.
4) Again on the parameters tab, change the null into a Luxus light, but this time choose an 'infinite' light.
5) Under light settings on the Infinite light plug your desired HDR map into the Environment map texture
6) Render.
7) Adjust the gain on the sun and the environment map until they match. You'll need to use Linear for this to work.
Here's a better example which uses the above methodology. I added the walkway not merely for aesthetics, but also for bounce light which is otherwise missing if you use pure environmental lighting. You may wish to do something similar.
...does this same setup work in Reality? If not, BobVan, any clue how this would be done?
Sadly not. Reality 2.5's IBL system doesn't give you any control over its visibility nor does it allow you to choose what type of light it becomes. Unfortunately, for a visible IBL you need an 'infinite' light which appears to be unsupported in Reality 2.5. Perhaps Reality 3 will fill in the gaps, but until then it doesn't seem possible outside of manually editing the exported files.
I've posted all the links to my IBL files in the Luxus discussion thread here. Feel free to make use of them. It will be interesting to see what people do with them.
If you want mapless IBL lighting in Reality just remove the map in the light option. Nice render Artini this why I say I am not oppose to also rendering in 3Delight especially since it has been improved. I also dont mind post working like I do with skies or lets say you have a character that won't or is wearing something that won't work well in Lux render it in 3Delight and merge it in PS. It may be due to the fact I used to photocollage in PS prior to rendering here are some samples of my PS works http://www.flickr.com/photos/37909888@N05/6455670007/in/set-72157628280882937 http://www.flickr.com/photos/37909888@N05/6455670119/in/set-72157628280882937 http://www.flickr.com/photos/37909888@N05/6455672829/in/set-72157628280882937
Thanks a lot, Bobvan. Below there are 2 more Daz Studio 4.6 Pro 3Delight renders
using light and environment provided by HDR Pro Sets Urban Recreation.
Very cool car paint looks good O\
OT my notebook's at the shop getting an SSD drive popped in!

...as I already invested in Reality and am on a tight budget I need to stay with what I have. Already wrote off 55$ on Hexagon because of that application's terrible instability and not about to do the same with Reality.
Where I am concerned, Luxus just came out too late.
Great renders on the whole, but, while the vehicles and everything else look really nice and 3D, for some reason, the figure looks a little flat, sort of like a cardboard cut out. I can't put my finger on why that might be though.
CHEERS!
I do like the idea of those IBL's and if you were to find a way of uploading them I might be interested in them.
CHEERS!
It's already been done. Check the Luxus Discussion II thread I posted a link to earlier. It has links to all of the IBL presets I created. I had to upload them individually rather than as a whole, but the accompanying metadata is intended for use on the entire set rather than individual lights. I'm working on a render at the moment (It's 'cooking' as we speak) which puts one of the IBL's to use so as to better showcase what they can do.
LOL, sorry, I missed that, I'll go back and look later.
CHEERS!
I have to try different light positions - may be it is because of the light coming from the back of the figure
or this gamma 2.2 in Daz Studio making it weird...
A work in progress. Currently only at around 550 samples, but it needs longer due to the use of Subsurface Scatter in the skin. I'm using my own IBL preset in this example (Chiricahua Plaza in case you're curious) with no modifications made to the lighting solution at all.
The Nishta texture was used on both adult and child, with some subsurface scatter added in with Luxus. Cloth material (silk) used on Ysaris outfit and Quickwind top, as well as the K4 Cheyenne cloth. The woman uses Nishta morphs, while the girl uses a combination of the Lilly and Jamika morphs I transferred with GenX.
It will probably need at least another 500 samples to clear up completely. I'll update when it's finished to a good standard.
Mmm,
Not sure really, we never had gamma in DS before so maybe you could try it with it turned off.
CHEERS!
Yeah, looking good so far, the fully baked version looks like it could be worth the wait.
It'd be interesting to see the same render but done in 3DL just for comparison.
CHEERS!
Below is a render of P3Design's Leia fo Genesis. Also used PH Bubblegum hair and lights from HDR Pro Sets Urban Recreation.
Rendered in Daz Studio Pro 4.6 with no gamma set (1.0).
Rendering Time: 15 minutes 33.1 seconds
Hmm,
Not sure that light set is working for this type of render. There doesn't seem to be any depth or shape there. Perhaps try some Lantios lights.
CHEERS!

Thank you for the hdr presets on sharecg, much appreciated! Here's just a quick test of Bryce Park HDR prop following the method you outlined, only ran a minute or two on my i5. This technique has tremendous potential for realistic renders and the price is right!
