Reality Plugin. How to use?
Hello.
I'm instaled Reality Plugin for DAZ.
An every sites this plugin names is a best and easiest way to make cool renders. I watched video about quick work with Reality where was all very simply.

I did the same. But renderes is very very bad. Two big blur.
Help me please with settings.

The image looks absolutely ok, I see no problem. You simply did not render it long enough for a good quality. Luxrender is different from the native DAZ render engine. It literally never finishes rendering. You decide when the image looks good enough and stop the rendering process. Depending on several factors like scene content, lights, image size and PC power, this can last many many hours!
Just be patient, let it render some more time and all is good :-)
Look better, please. Click on the picture. All blured
I would not call that blurred, I would call it grainy.
And as I said above, this is normal when you render only a short time. Let it render a much longer time and the grain will disappear.
In the bottom line you have a S/p meter, which means Samples per pixel. How high was that number when you stopped rendering?
The S/p value is a rough meter for render progress (besides the image itself of course), the higher the number, the better the rendered image.
Well. I just used very high resolution and you don't wanna see blur.
Now I did two rendfers of one scene with 618 pixels.
Left is render with 3Delight (1 min 45 sec), right is Reality+Luxrender. I wated 7 min, and Luxrender did this render 3 times.
7 minutes is nothing for Luxrender. In Luxrender you usually have to render several hours to get acceptable results. Luxrender is used by people who go for Photo-realism in their images. If you like the results from the 3Delight render, there is really no need to go the Reality/Lux way. Luxrender can give you very good results and high quality, almost photo realistic renders, but this takes a long time. Render times of 10 to 20 hours are common, even on very powerful computers.
So, again, after 7 minutes of rendering in Lux this is simply normal :-)
I admit to having little patience and have tried Reality and also Luxor. It is true that with reality you have to take a vacation from life for some hours before you can get rid of the grain, although there is an option which i think if i recall is called SMG that can deliver almost instant results, don't quite know why i stopped using that.
What i have found by experimentation is that using omnifreakers uberenvironment set to the highest quality in conjunction with other lights, spots and distant lights for example. you can get really good quality results with 3 delight. Much better than your example although it can take maybe an hour to render.
You realy don't wanna open your eyes.
After I put this picture I still waited another hour. No changes.
I did't used difficult scene. Only one model, one light, no background.
I have very powerfull PC and I waned to use LuxRender only because 3Delight is a very stupid rendere, which working very slow and don't use GPU. LuxRender use GPU and works more faster. But I need to know right settings for It
3Delight is one of the most powerful render engines available. Several Hollywood movies have been rendered with 3Delight. Please check http://www.3delight.com/en/index.php if you do not believe.
Luxrender is also a great render engine, but works completely different. And if you are not satisfied with a Luxrender image after 7 minutes of rendering, I do not know who does not want to open his eyes. Sorry, but this topic is finished for me. Maybe someone else will help you further.
All modern powerfull renderers use GPU. Octane, V-Ray, Mental-Ray and others. Maybe 3Delight is good too, but in the DAZ this renderer work terrible.
I asked to teach me how to set up Reality and LuxRender for get pictures as on promo-posters of Reality. If you know - help.
I have used all render engines 3Delight, Lux and reality.
My preference would be Reality, because you can alter lightning while rendering and reality 3 is even more promising, but only the Poser version is out yet.
What said above is true, Reality uses the Luxrenderer and it does take much longer than 3Delight no matter how you keep tweaking.
3Delight is a biased renderer and Lux(Reality) unbiased.
Although in my opinion Lux and Reality outdid 3Delight in rendering results in the past, I found that is no longer the case.
Because Lux (and therefor reality) uses light very differently because of the biased and unbiased story, the rendering times are different and they calculate the results differently.
The blur that you talk about is indeed grains, which ALWAYS appear when you render within Reality.
The longer you let your pc work, the less grainy(or blurry) it will get.
There are some tricks to keep the grains to a minmum and that is a good use of meshlights.
Reality is sensitive to be overlit or underlit and that will express itself in grainyness or even firelflies (little white specks).
So my question is how many lights and what kind of lights you are using in your scene.
Also, what resolution are you using?
And what are the specs of your pc?
There are a whole bunch of things you can do to tune down the rendertimes but I found lots of them compromising with the quality in the end.
I am in no sense a professional, but I have made 100's of renders and these are my findings so far :)
I let my renders work for sometimes a whole night with an 8-core i7-4770K working with 20 ram.
Mostly until I reach 1000 S/p (or 1k S/p) which takes my pc about 8 hours with a resolution of 2000.
EDIT
And please be patient with the people who are trying to help you!

First render Reality: Reality sun, 1920x2484.
Render with 3delight: DAZ Distant light, Uber Environment2, 618x800
Second render Reality: Reality sun, 618x800
As I know, renderers which use GPU works more faster. Octane for example. (Transformers-3, Life Pi and others).
In the all info, which I found about Luxrender, and in all promo-video (look link at the top) LuxRenderer looks as realy fast renderer. And examples of renders which was made in Lux looks perfect, without ugly blur. It was a reason why I'm instaled him.
Not surprisingly it is all about lights and materials. 3Delight, being 'native' to Daz Studio has a lot to recommend it. Not only is it (as has been mentioned) a potentially very powerful and effective render engine it also has the benefit from it's long use with Daz Studio of having people creating products that utilise features and functions of the engine. That means you can, should you so wish, drop a figure into a scene, slap some clothes on it, chuck in a light set and hit the 'make art' button. Results may vary ... ;)
LuxRender is a very different render engine to 3Delight, both in how it treats light but also how it handles materials. Considering those two components are critical to a decent end result there is immediately a problem! Both Reality and Luxus act as bridges from DS to LuxRender and both, in their own way, do their best (which is actually pretty darned good!) in taking DS/3Delight-spcific material configuration and converting that to something that LuxRender will both not choke on and will also have a good chance to looking decent.
LuxRender will take as long as it takes to derive an image of the quality you want. Yes, that is generally way longer than 3Delight and longer than Octane, etc., etc. A lot will come down to the scene set up. There are a few documents around, a fair few by Paolo (who wrote Reality) as to you can get the best results in a decent (relatively!) timescale.
The main thing is to set up the scene with your final render engine in mind - that includes what lighting, etc. With a bit of forethought you can achieve respectable results is not too long a time. With LuxRender the main things to bear in mind are: do not have too many different light groups and to take care over the glossiness of materials. If you are after just portrait studio type images, take a look at some of the free props released by Callad - use of her light/prop sets can produce good results very quickly.
When using LuxRender bear in mind what it is doing. If you have a render in a closed box (such as a room) the light will (depending on glossiness of surfaces) bounce back and forth an awful lot. If your lighting is mainly via the Sun and your scene is indoors look at the use of Light Portals so that LuxRender does not waste it's time calculating light that will 'only' bounce off exterior surfaces.
Do some research, find out what others have already stumbled upon so you can learn from their discoveries and mistakes. Ultimately what render engine you use will be what is best for you and your needs.
I'm looking for good renderer special for interior room with all walls, with floor and with ceiling, where impossible to use sun light only, where need to have global illumination. If LuxRender can to simulate It, It would be best for my idea.
Main I need to know It's how to setup rendering for remove blur.
Reality-plugin has more settings than 3Delight, and I did't found info about more part of they.
By blur do you mean the effect of a narrow Depth of Field or the effect of the 'final' image being slowly built up as the render progresses?
The solution for the former is to tell Reality to either not use DoF, or if using it to specify a higher f-stop value (note doing that in LuxxRender does NOT affect DoF, just amount of light).
For the latter one simple solution is - stop looking! Not actually kidding on this. If you minimise the LuxRender window the render will actually progress a bit faster as it does not have to keep refreshing the screen display/ouput. If you do loo, then look for at least the amount of time specified for refresh rate (default is 12 seconds?) otherwise you may not see a change - keep an eye on the status bar and look for it saying 'tonemapping'.
Will the background of the interior matter to you, or could you 'just' use a DAZ primitive cube? I think it sounds like you may get a lot of mileage from Callad's realty light props - I think she has them up on ShareCG and her deviantART gallery.
By blur I means blur effect - colored pixels.
I makes scene in the room interior - 4 walls, floor, ceiling, one wall has three windows, another one wall has door.
No matter how much you want it to be LUX Render is NOT faster than 3Delight. The only way to CLEAR up lux render images is to let the image RENDER for HOURS at a time EVEN on your PC. My PC is more powerful than yours and requires 8 hours or more for a CLEAR lux render. That is why I do not use it any more.
SPPM can get 'faster' clear images than Bidir/Metropolis...but so can proper lighting. So can Hybrid and SLG (but SLG has limited materials support...it is the straight GPU version of Luxrender). Setting up the proper combination of integrators/renderer is going to speed things up a lot.
Read through both the Reality docs and the Luxrender wiki...
http://www.luxrender.net/wiki/Main_Page
DS lights ARE not Luxrender lights, no matter what kind of conversion they go through. Luxrender does very well with 'mesh' lights and IBL, not so well on 'math' lights (point/infinite/so on..the lights that exist as mathematical concepts for a render engine more than anything physical in nature)...often much easier to set up than 3Delight. So setting up proper lights should be a priority. Proper lighting will go a long way to improving both the 'finished' render AND speeding it up. Also, making sure your materials are converted to Luxrender materials, as opposed to relying on the exporter to 'guess' what they should be, will speed things up, some, too.
But when all is said and done, nothing less than a couple of hours, short of running a network render on about a dozen machines just like yours, is going to be what it takes. Generally, when Luxrender has a contest, they will specify entries need to be 1000 S/p or more...which translates, for most folks into 8 to 24 hrs of rendering.
So, if it takes your machine 8 hrs to reach 1000S/p then do the math to figure out how many more, just like it, you'll need to get it in 7 mins. Using a quad core machine as an example, you would need about 280 (70 machines) cores to cut that 8 hours down to less than 10 mins. Now, that's why a straight GPU renderer can do things so much faster...the shear number of available cores to do all the calculations. A moderate level video card will have at least close to 100, but often over 100 cores to handle the job. But the big drawback/fault of straight GPU rendering...a memory limit dictated by what the video card can hold. Being able to use system RAM will slow a GPU render down, a lot.
Yes, Octane can do some blazing fast renders...but unless you want to shell out major cash for a very high powered video card, with lots of RAM, you are limited, severely on size/textures...that's one reason why lots of Octane renders are 'simple' scenes...single individual figure or something. Limit Octane to just 4 or 8 cores and see how fast it is...
But something like 3Delight or Luxrender (both are CPU only) are not limited that way...but are slower due to the fact that they don't have access to as many processors (3Delight has a license limitation...a 4 core lock on the free, stand alone version...no lock on the included version in DS, but can only be used from with in DS and no network rendering) and more can be purchased. Luxrender is a free, open source project with no core limits or network limits...so, technically, if you can throw enough processors at it, you can get it run as fast as you need. Yes, there are things like overall network speed that can/will introduce bottlenecks.
There isn't a renderer that exists, anywhere, that does everything...they all have some sort of compromise built in. Raw calculating power and memory are the two main ones...and right now, short of a network/bank of very powerful computers working together, there is no way to have both. And pretty much the only renderer that is capable of scaling up to a large number of machines that isn't going to cost a small fortune (not counting hardware) is going to be Luxrender (yes, you could actually build quite a few 'headless' 8 core AMD based machines running a Linux distro for what it would cost to get the top end video card to get the most out of Octane...and network them to run Luxrender).
Great reply - lots of detailed info here.
One question - by "lots of RAM" How much RAM are you talking about?
Thanks to all who took the time to answer this question. Lots of good info.

Octane can use 1 and 2 GB cards, but shines on the big ones...like the 3 and 5 GB Quadro/Tesla cards...and yeah, last I knew it only ran on Nvidia hardware. It can run on some of the gaming cards, too...again, with the best results on the 3 GB and larger ones. The 4 GB GTX770 should run it...
And really anything less than 2 GB is going to be too restrictive as to scene size/composition.
Thanks for the info. Out of luck since I have ATI Radeon (2 GB) but not NVidia. Looks like it's Lux or 3Delight for me :)
Eventually Octane will have support for other cards (read AMD) but I haven't been paying any attention to it, because it's out of my price range...
To me, all those GPU render engines are very limited, because
- you need a very high end graphics card and those are really expensive
- sometimes you are limited to a special brand of GPU (Octane supports only NVIDIA cards)
- with your scene content (especially textures) you are limited to VRAM (the RAM of your graphics card) which makes it impossible to build bigger or more detailed scenes
Like I said, for the price you'd pay to be able to do it, it gets a little ridiculous...the top end Nvidia 'pro' level card with 5 GB of VRAM comes in around $3K...for that I can build 6 8-core AMD based machines to network together and each of them can have at least 8GB of RAM.
It is grainy, not blurred.
