I got it too but haven't checked it out yet. I still don't get half of DS, so I hope I can understand this. Sooo glad there are PDF's. Videos just don't work for me,
But again that's technically the same as ghost lights (e.g. emissive planes), isn't it? That's what I'm trying to avoid.
Yes but I'm not particularly talking about this set, just using it for demonstration of an internal environment where you can't access any light from outside. With this set I can just hide a wall or the ceiling or whatever, but some sets don't allow for that.
When I first started with Iray (oh my god, spell check changed that to Iraq LOL!) I bought a bunch of lighting stuff that I think is totally unnecessary now... One might be interesting though I still haven't used it properly. I has ceiling light and various sconce lights you can put around the room that is functional decorative lighting. I forgot the name of it though sorry. Another thing I got at the very beginning are a bunch of decorative standing and table lamps with bulbs you can crank up as real lights. I'm rendering a scene with one now. It's pretty cool, the light comes right out the lamp and cranked up, it lights pretty well and looks like a warm incandescent lamp for home...
No. Ghost lights aren't just emissive planes, they're emissive planes with opacity a fraction away from 0 which causes all sorts of screwiness.
IMO removing walls etcetera to let light in damages the realism of the final render.
That looks like Gymnasium. I was hoping it was the Small Sports Hall as I have that one. Anyway... Here are my recommendations:
I hope this will help. I could tinker with the Hall, but it has more windows so it might not be helpful.
You read right.
For me emissives add a lot of time to the render. Plus they seem to produce more grainy light overall.
This is true up to a point. Iray has to calculate the light, how it bounces and all that stuff, (which I sort of understand but don't quite know how to explain,) for each and every single emissive polygon. Something I learned when Iray was still new to DS, from someone who actually could explain it. Anyway, the original Ghost Lights from KA, either the instructions he shared or the original set he released, use single poly planes. That's why they are fast. When you make an object with 50 polys an emissive, the render time is going to increase. I think it increases exponentially, but I'm not positive on that. Regardless, the more emissive surfaces you add to scene, the longer it's going to take to render to a clean image. The gentleman who explained this to me, also said the same is true of point lights, but that spotlights and distant lights were only one light source per, so didn't add to the render time.
I can see how making various parts of a scifi set emissive could really bog down a computer. Most of the things I make emissive are really low poly, if not a single poly plane.
This is very good to know! Thanks.
I tend to use pointlights, or spotlights if I need to do a indoor scene and can't get any light from outside. But I also do tend to remove ceiling or walls to let in light from hdri if possible, and now and than I use lightset if I have a fitting one :)
My two cents, with inflation- try one of the portrait light sets. Just because they're labeled for portraits, some work quite well for other purposes, particularly with an additional light.
I think the product with the wall lights, etc was ALR
The "Intensity" parameter that you use in 3DL doesn't do anything in Iray. The equivalent parameter for Iray lighting is "Luminous Flux(Lumen)," which is right down near the bottom of the list of light properties. Not at all obvious.
I have just been using soem ghost lights and had success. To start with. Went back to the scene and needed to adjust the lighting due to changes in poisitions of the figures and founf that nothing I could do would change the materials on the main light I was changing position of. So I deleted it, loadeda fresh prop and ... it would not take any materials! I ended up coopy/pasting from ghost light I had remaning in the scene, which did work .. what the ... proverbial?
@simonjm I've never had that happen, interesting. I usually select the Ghost Light and do all those things from the Surfaces pane, even though KA (KindredArts) has the convenient click presets.
@simonjm I have never had that happen either. And I use them in almost every render I do. I would contact KindredArts, or comment on the commercial thread for those and ask him. He is very good about answering any questions and addressing any problems.
What I've determined with materials presets is they apply to the material zone of the same name. So if you have two different props from two different sources, if they have the same material names, the preset will "work"... KA's ghost light presets apply to "Arrow" and "Light", so if you decide to make a plane emissive, renaming the material zone from "Default" to "Light" will allow the Ghost Light presets to work!
This also means if you change the name of a material zone of an object, that object's own Presets will fail to apply to that zone.
And the one that trips me up the most… If the preset is a shader, you have to have the object selected in the Scene, and the material zone(s) selected in the Surfaces->Editor! (Gets me at least once every bleeping scene I create!)
That's the thing - no name changes, 3 of the ghost lighst added and tried slecting the prop, the prop and surfaces, etc., and zilch!
Wow. That is really weird.
In case you haven't seen this in the Gallery, it's a great Batman. Neat postwork.
OT: Oh wow, another huge snowstorm on the East Coast. 13-15" or more! Meanwhile, just to rub it in (not really, was going to share these even before I found that out) it was a balmy 76 degrees here in Pensacola today, and I went out to see Stetson. Hadn't seen him in about a month (busy, and then the Mom thing happened so when I get a minute, I'm over at her specialized care place) When he heard me calling his name, he looked up and nickered then galloped over. We're under a high wind advisory and it was SO pretty to see that mane and tail blowing. His hair wasn't braided so it was over his eyes, blowing, but I braided it before taking pictures. He seems to like it out of his eyes, and he has insect repellent on his face to keep the bugs away. (Never put it near the eyes except to the side, if you put it over the eyes the sweat may make it run down.)
What I wanted you to see, because it will be gone in a few days, is his winter coat on his sides. This is how horses shed out, with a bit of brushing. One of the gals working there brushes Stetson a couple times a week and braids his hair. So cute! So the reddish hair is his winter coat, the gleamy black is his summer coat. No conditioners or hair products added. As summer kicks in, this will begin to bleach out a bit, so Spring is really the best time to see the shiny black.
These didn't transfer very well from the phone as I had to send them via email, and it compresses/mangles them more than when I setup a wireless transfer. But you get the idea. Stetson says hello to all of you buried in or soon-to-be-buried-in snow. You can laugh at us when we baking in the summer heat this summer. Oh, and supposed to be a higher than average hurricane season again. Fact: the Panhandle of Florida was the only part of Florida that didn't get hit with a major hurricane last year! Harvey came straight up the middle of the state but didn't reach that far West. So sad we never hear much about the Keys, which I'm sure are still massively decimated and struggling to recover, a yaer later. (and the Houston / Texas flood areas.) Thoughts and hugs go out to those who got hit with the tornados last night.
Again, sorry about the picture quality.
I've mentioned this before, but this is Infusium23 for people (a leave-in conditioner). If you like how this looks, Sally Beauty supply has it in big bottles and it's cheap. Smells good too. Like a salon-expensive conditioner. Not fruity, more like fresh linens fabric softener.
This one REALLY shows you what a horse looks like with the winter coat on the sides vs the new shiny summer coat coming in. And that Stetson is extremely well fed and not ridden enough! (About to change, before the summer gets here. Going to start riding at least a couple times a week while it's still Spring.)
And the massive "I was a stallion 9 years" neck and chest (partly shown.) And also the "see how many boards I have broken that my owner just reimbursed the stable owner for?" (see background fence. We're having to use thicker boards for Your Highness pasture.) You can just read his mind, contemplating which one to break next. (The horses in the next pasture play with him over the fence, and they lean into it.Stetson is very muscular with that chest, so it doesn't take much. They quit using 2 x 4's.)
Hello Stetson! Thanks for sharing - I like the hair braid.
Stetson is gorgeous!
If anyone wants to send moisture to the high plains of Texas, we'd surely like some! I think we've had all of 1/2 inch of rain over the last six months.We've had problems with some bad grass fires lately.
Such a beautiful boy! Love it when you post pictures of him. I had no idea their summer and winter coats could be different colors.
We are expecting 1 to 3 inches tonight, hoping they are wrong. After that its going to go all the way up into the mid 40s over the next week. (note the sarcasm there, its supposed to be spring darn it!)
Oh yuck. What's your summer forecast? Ours is hotter than usual and I believe it is supposed to be drier too. (Until the first tropical storm hits, then we can get a month or more rainfall in a day.) Are you on voluntary water rationing yet? I read a couple weeks ago about the (IIRC) Cape Horn area running out of water. This is the article. Showers should be limited to NINETY SECONDS. Wow.
I bought this some time ago but never got around to using it until today. It's Golf Course Bundle which has three products: Golf Course by Mely3D, Golf Course Props, and Sporting: Golf Poses for Genesis 3 by FerelFey. I used all three in this image.
The course is lovely. It's a tropical course given the palm trees and is relatively flat, although the sand traps and ponds give it some vertical variation. The predominant color is green as you'd get in late-spring early summer. The props provide bag, balls, clubs, and electric and hand golf carts. With the hole flags, benches, and fences from the course, pretty much everything you need to set up a golf scene. The poses are a little different in that they are labeled "wearables' instead of poses. When you use them, they not only pose the figure but add a club with the right pose to the hands. There's also poses to put the figure in the electric cart, on benches, or at different points of the course. They work for V7 and M8.
I was using the set as part of my current dForce explorations to add footsteps to surfaces. In this case, when your ball lands in a sand trap, you have to walk through the sand to reach it. With a normal ground surface, it looks like the golfer leaped or transported to the spot. By using dForce, you can add footprints that give a more realistic look as shown below.
Below: He must have flown or jumped to avoid disturbing the sand!
This was also the first time I used Chunky Knit Sweater Outfit for Genesis 3 Male(s). As soon as I saw it in my runtime I thought it would work well as a golfing outfit. Of course it may be more appropriate for colder climates like Scotland, but Florida can he cold in parts of the year.
@rgcincy Love those footprints! They make a world of difference. And I'm loving Tiger Woods coming back on the golf scene. He's had so many back surgeries/other surgeries, I worry every time I see him swing a club with force.
Hm, OK, didn't know the opacity would make such a difference.
Probably true, but realism is not always the goal. Sometimes unrealism may look better.
I'm one of them, I just think that many tutorials sold here - especially video tutorials - are heavily overpriced, compared to how much work it takes to make them (I've made several myself, so I know).
Stetson is gorgeous!
Yes, it is Gymnasium, an older 3DL environment.
Thanks very much, useful info, will try to experiment with these things and see how it works out...
So that is a bad thing?
Spotlights and point lights don't seem to work very well in a larger environment though, unless you use a lot of them.
Well "Intensity" does work with spotlights though you have to set it very high. But not for distant lights it seems. I can't get "Luminous Flux" to work with distant light either, though?
Thanks, good idea, will try that.
