Yes, all the gain parameters in Reality are what you see in Lux, but there are a couple of things to know. First, Reality allows you to set the gain for each light but LuxRender uses light *groups*. Now, a group can contain a single light but that is a special case. So, keep that in mind. For example, let's say that you add two mesh lights and you set the gain of ML1 to 0.75 and the gain of ML2 to 0.25. And you don't change the group names so that both lights will be in a single group called MeshLights.
Now, in LuxRender, you change the gain to 1.2. That will multiply the gains of both lights. So, effectively you will have ML1 at 1.2x0.75=0.9 and ML2 at 1.2x0.25=0.3.
Second, because LuxRender works in terms of light groups the gain is always set at 1.0 at start, no matter what is your value in Reality. For example, let's say that you have ML1 by itself in a light group called "Upper Light", and you set the gain for ML1 to 3.75. When you start LuxRender you might be surprised to see that the gain for the "Upper Light" group is still 1.0, and think: son of a gun, it didn't work. That's would be incorrect. The 1.0 gain in Lux is a *multiplier* of whatever gain is specified in the light. So, setting it at 2.0 would give yo ua light at 7.0 gain (3.75 times 2).
All clear as mud? ;)
Okay, will try some of the Film Responses. I'm doing a different scene, one with a dark skinned character wearing white, simply because I'm a glutton for punishment. I won't mess with those on that one yet. Maybe after the first one, I'll try those on it.
Yep, I understand you completely. (I really am an MP (mini you!) I do already make each light it's own group so I have control over each light in L.R. and I think that's a very important thing for newbies to do / understand. Thanks!
Here's that render with only the IBL (Summi Pool, HDRlabs. I think you folks would like it) with the dark skinned figure but wearing the white dress. I did have to do some postwork to tweak the midtones/shadows a bit in Corel Photo Paint. (LOVE that Adjustment Lab. Unless Photoshop, all the sliders are in one place and easier to use.) See below. It's not a masterpiece but I am less than a week into this, so quite happy!
Paolo- that one other question- slipped by you I think because I was keeping you busy- does that Environment Color in Lights in Reality change the light color at all if I am using an IBL, or is that ONLY for when an image isn't used in IBL?
I think that it's a rather good image, especially for the time you have used the program. About the IBL env. color, no, it will not affect the overall light if you have a map.
Cheers.
With this Subsurface Workshop product work in Reality? (And yes, I know Reality has its own materials.)
Products like that don't generally work because they are made for a specific renderer. It doesn't not work with Reality in the same way that it doesn't work for 3Delight.
Cheers.
Here's my render, the speed is incredible with the latest updates! A fairly dark scene with just one light rendered so fast!
But I am having an issue with the recently released presets for G3M. Every time I try to install them, it says I can't because I'm not the author, anybody else having problems with that?
Toyen, that is amazing!!! I haven't tried the preset yet so don't know about that.
Someone on my thread (here in Art Studio) asked me about the speed comparisons between Iray and Reality, and frankly in the renders I did, Reality had a slight edge so far as when I stopped the render for it to be to my satisfaction.
I'm still learning how to tweak skin in Iray, one gal I tried (my first G3F) in Reality was Ms super-sheen. Is there one setting in Reality that I should try first to reduce sheen? (She even had Toyen's dude beat for the sheen! On him, it looks good, on her, not so much!)
Thanks Novica, I really struggle with Reality's material setup to be honest so can't really give you much advice other than trial and error adjusting the values and see what that does by running a render (since the material preview really isn't enough for me)
That's why I was hoping to use the preset for this render but they aren't working unfortunately : (
Hi Toyen.
Thank you for posting that great image.
The installation of the preset does not have any restriction about the author, I suspect that you are using a procedure different from what you should use. Can you please describe the steps, starting from the Reality window, that you perform to arrive to that message.
About the material editing, did you see my series of articles titled "Take control of your materials"? If you need anything clarified I will gladly help, just letr me know what you would like to know.
Cheers.
Can you post the material setup and the result? That would help me to point you to the right direction.
I wish I could, I can't remember what character I loaded and I regularly delete the files of the ones I don't use (a good tip from either a video I saw or in the RUG. Thank goodness it explained the file extensions, those were Greek to me.) If I encounter it again, I'll definitely give a heads up. I've also got to get to the materials section in the RUG, I don't know if it has a section for skin or not. Thanks for the attempt at helping though! (Edit- I think it was either Kathy or Summer, both G3Fs.)
In Reality's menu I go to Presets-Import-Select the file and after hitting Open I get the message " A preset was attempted to be updated by a user other than the original author. That operation is not allowed."
In case you folks haven't seen it- The new Official Reality Forum is back on preta3d (dot com)
It's never optimal to have your product's forum on another site (not referring to this thread, the forum itself was on another site that Daz acquired.) There is also a gallery to post your Reality renders. I am mentioning this because I certainly don't want Paolo to be pulled in multi-directions, trying to keep up with a thread and a forum. It's up to Paolo if he wants to continue monitoring the thread to answer technical questions, but the Official Reality Forum is now active, and on his site.
For me personally, I have three years invested here with sharing the specifics of my renders (including what doesn't go right) and what I've learned, and I am going to continue doing that aspect here. I like including my settings for people as a starting point to tweak and experiment, because the Art Studio is designed specifically for that. And of course, Art Studio has awesome regulars who hang out and chat! (You fit right in Paolo!)
For questions / technical help, I want to support Paolo's efforts to have that in the Official Forum so he's not typing the same information in two different sites. I think it's awesome for everything Reality to be in one place. Paolo was a gem for doing the live chat a week ago, and he's been monitoring the thread ever since our chat last week, but that takes a lot of effort to monitor a thread and type up the technical responses. It was never the intention for him to commit to monitoring the thread, it was just a scheduled hour chat, and I am SO impressed with Paolo for his willingness to be available to answer questions, and I hope folks take advantage of his new forum. I think we'd all still like to see renders here too!
I just want people to know that if Paolo isn't on the thread as much, it's because there is now an established forum for technical help. I'm not trying to speak for him as to whether he will monitor this thread, but I think logically it makes sense to use the forum on the product's site and be in control of the information / moderating / structure.
FYI, if you haven't noticed, I've been indexing the topics, see the second post of the thread. I'll continue to do that for a handy reference.
That means that the preset is already present, you are installing it twice.
In the Preset Manager, look for the G3M preset, it should be already in there. Also, you can do a simple test, add G3M to the scene and look in Reality. In the preset column you should see the name of the preset. Please note that the preset will activate only for G3M. If you use a figure derived from G3M, like Michael 7, it will not show, It has to be the base G3M.
Hope this helps.
About two parameters that affect the shine all the material: the specular color and the glossiness strength. The specular color determines how much light is reflected by the material. Brighter colors reflect more light, darker colors reflect less. For example, and mid gray Will reflect 50% of the light, which is a lot. It's very likely that your shiny material had a very bright specular color order specular map.
The glossiness strength determines how polished the surface of the material is. Higher numbers give a higher shine.
So, the final result the pants on the combination of these two parameters. That is actually a diagram in the RUG that shows the different effects of changing the brightness of the specular color.
Hope this helps.
Well, I knew about specular and I can see the color box, but for glossiness Reality has horizontal and vertical, for which I have no clue. Don't worry about it, I need to read the Materials section.
Here's one I didn't have trouble with so far as too much sheen. A good one to experiment with- Destiny's skin, she's a G2F. Using Fisty's lace shaders which are new to the store today! I'm still trying to figure out though how to lighten the scene without everything washing out, I adjust midtones and shadows, etc using Corel's Image Adjustment Lab, which I actually prefer over Photoshop as the contrast, saturation, temperature, etc is all in one place.
L.R settings: ISO 210.5 Shutter 0.103 F Stop 9.10 Gamma 2.64 (otherwise the shoulder pattern washed out.) Light 1.91 (00000) Then tweaked in Corel to make the skin more ruddy and less gray/blue. IBL: HDRLabs Summi Pool.
Hi Novica.
Thank you very much. When Reality started we launched it here at DAZ and we had, for about a years and a half, one of the most popular threads in the Commons forum. At that time the DAZ forum software could not handle more than 100 pages and we had something like 13 splits, if I remember well. Things changed over the years, the program expanded, and other factors kept me busy so that I did not hang out here for a while, but I love the DAZ community and I'll share all the time that I can.
I'd love to see renders here too.
I just wanted to thank you again for all the support and kind words. I have this thread bookmarked so I will receive notifcations when people post. Whether you post here or in the Official Reality forums, I will do my best to address your questions, suggestions, and feedback.
Cheers.
That is also csalled anisotropic reflection. Don't worry about it. If you keep them linked together you can enter a single value.
Nice image. In that case I think that actually you can add some shine to the skin to make it more realistic. Skin is a very reflective material. It reflects a lot of light but, because of the texture of the surface (pores and so on) the shine is not glossy. So, for skin, you need quite a high value of brightness for the specular color, and a modest glossiness strength. Something that can work well is 50,50,50, up to 64,64,64 for skin, and glossiness at around 7000.
Cheers.
It's good to know we can still post the questions here- and yep, they have extended the number of pages so we indeed have "monster threads." I agree about the skin shine, I've been reading / taking notes on the RUG and am in the "Volume" section at the moment (re: SSS)
Thanks pciccone, they are probably already installed.
As for the material editor, it's just because I was spoiled by Iray and 3Delight IPR option to see the change to materials in my actual scene under the current lighting instead of a preview window : )
I might try to get some custom presets for my characters in Reality though since it really is my favorite renderer due to all the cool options you can make to the image as it renders.
That would be very cool. And consider the possibility to sell them at DAZ. I always thought that there is a great potential for vendors and artists to make presets for Reality. If sold at very reasonable price I believe that they will be attractive. It's an un-explored market.
Cheers.
Yes you are right, since Iray took over, Reality and Luxrender were left kind of unexplored which is a shame. I just made my custom skin preset for Gianni 7 so I'm gonna post a render soon : )
So I cannot save my shader, neither as automatic nor universal preset.
I right click on the "Face" material for example, and:
When I select the "Save as Automatic Preset" option, I get "Error while trying to save the preset"
And when I select "Save as Universal Preset" option, I get (see the attached picture).
Anyways, here's the Gianni render, I need to look into the dark eyes issue some more. I mostly just adjusted the SSS a bit and turned down the metalicity and used the specular/glossy settings instead.
Hi.
I assume that you have a scene saved with that version of Gianni. Is that correct?
Yes I saved the scene.
OK, the issue might be with a corrupted or badly installed preset database. You can try the following procedure:
- The preset database is in the Documents folder, in the Pret-a-3D/Reality folder and it's called ACSEL.db
- Make sure to close Studio and Reality. If you have Reality for Poser as well then close Poser and Reality for Poser.
- Rename that file. For example set it to ACSEL_old.db
- Re-install Reality. That will re-create the preset database
- Start Studio
- Call Reality
- Re-install the G3M preset
- Load your Gianni scene and try to save the preset again
Hope this helps.
Thanks a lot, that seemed to fix the issue.
I wanted to test the preset by applying it to another figure but unfortunately, I am running into an issue I was experiencing before, Reality does not recognize the figures I loaded into the scene.
I have two figures in my scene in the picture below but the Materials window is empty which means they are invisible to the plugin and will not render.
Is there anything I could do to fix that?
Also, I have noticed a crash issue when trying to switch the texture type from Mix to Image Map in my scene with Gianni, it crashes DS every time I try to do that.
