How To for Lighting & Shadows Daz & Poser
« on: March 12, 2013, 04:57:54 PM »

For Poser lights, please check posts below.



I always check the new images that are put up by various members for the Showoff Thread and others.  We have some pretty amazing artists in here and some new artists that are improving by leaps and bounds.

One problem area I have noticed is lighting and shadows.  There are some great light sets and preset shader lights that you can pay for or get free.  I have used a number of them myself.  I particularly like the uber light presets for free on Sharecg.  I have noticed the biggest problem with some images is a lack of shadows.  I use to have the same problem.  The biggest thing about that is you have to use raytracing or deep shadow (in daz, not sure about poser) in order for shadows to show up.  That can be a problem for some people, especially those new to the programs they use.  This thread is to help learn how to use lights and shadows, for both new and old alike.  Doesn't hurt to relearn things and you could find out something new in the process.  This thread will eventually be moved to the tuts area, but for now I put it here for people to see and use.

I have a collection of links for people to look through and use to help improve their images.  Anyone who has links or their own tuts regarding this process, especially when it comes to poser, please feel free to put them here.

Now to use these tuts, keep this in mind.  Both Poser and Daz use raytracing, ambient and occlusion when it comes to lights and shadows.  Despite that, how the programs interpret the information is different so adjustments need to be made depending on which one you use.  I even found a tut for subsurface scattering for Daz, I have not found one yet for Poser.  I mention this because it does help improve your images.

Another thing that everyone needs to keep in mind is not only do you have to remember the differences in programs, but also the scenes you create.  A light preset usually has an image to show what it looks like, but unless you are creating the exact same image, the lights and shadows will need to be adjusted.  The same thing goes for saving your own light sets or presets, they will work differently on your next render.

Ok lets begin...

Jamminwolf has created some mini tuts on how she uses lights.  These are images you can download and keep on hand for use, don't forget to save the information below the images that she gives about these tuts.

This next one is a pdf you can download to help with lighting in Daz4.  It gives a lot of help though says it's in progress.  Might want to check back with him after a while to see if he adds to it.

Another Uber Lights 2 tutorial a mini tut...

You ever get annoyed when you render is done and the skin and clothes are shiny when they shouldn't be, then this tut will explain how to get rid of that.

Here is a very basic lighting tut...

This is a tut from Adam at Daz on how to use Uber point lights.
http://www.daz3d.com/forums/viewthread/16970/

This one was originally created for earlier versions of Daz however, the basic concepts can still be used for creating light and shadow.
http://digilander.libero.it/maclean/DStutorial.htm

Another oldie but goodie giving great detail about lights and shadows and show images of how the differences look.
http://byudragon.com/Tutorials/DAZ/LightShadows/LightShadows.html

And finally one last good one showing differences based on settings.

I hope these links are helpful in creating awesome renders with light and shadow.  Don't forget to experiment.

This is the tut for sub surface scattering.  It doesn't give a lot of information, but it's a start.

This post is about Poser lights, though in all honesty I am not the expert, as I use Daz.  However, I can find tuts around the web that can be useful.


This is a basic tut from Smith Micro.
http://poser.smithmicro.com/tutorials/lighting_basics.html


This next one gives lots of information about lighting with images and explanations.
http://www.german-3d.com/tutorials/SF_Light_Tutorial/SF-lighttutorial_b.htm


This tut is quite extensive with images and explanations.
http://my.safaribooksonline.com/book/animation-and-3d/9781584506973/mastering-lights-and-shadows/ch03lev1sec1#X2ludGVybmFsX0h0bWxWaWV3P3htbGlkPTk3ODE1ODQ1MDY5NzMlMkZjaDAzbGV2MXNlYzQmcXVlcnk9


Another basic tutorial with examples you can follow.
http://designertoday.com/Tutorials/Poser/1717/Setting.Lights.e.Frontier.Poser.Tutorials.aspx


Another basic done just for the Dummies type of learning.
http://www.poserbydesign.com/news/index.php/component/content/article/72


Now please bare in mind that if you use these tuts the basic information is what you want, it is not necessary to buy things in order to have good lighting.  Use the above links and the information on them as a guide only to help you understand lighting better in Poser.


To help you with your lighting, please also refer to Parkdale Gardener for his tuts on lighting as well.  You can find his thread here...

Thank you for the links!!!

I have to admit, I do buy lightsets - and then I play with them. It is fun and this is my hobby ...

I don't seem to have any trouble finding tuts when it comes to Daz, especially one's that are good at explaining things.  Poser is a different matter.  I don't use it so I am not much help when it comes to it.  The tuts I find for it are no where near as in-depth as the one's for Daz.  On top of that, there are differences between the different versions of a program.  Experimenting can be a drag due to having to render your scene to know if what you did looks alright, though I believe that's more of a problem in Daz then Poser.


Now when it comes to using any program, I don't limit myself on the tutorials.  Just because a tut is for one program, does not mean I can't use the basics of the information in another program.  I do the same thing with 2D programs.  An example is as follows...


You need a light so you add one.  You want to alter what that light is doing so you go to parameters (In Daz) and look for the dials that allow you to change it...in most cases that is ambient, diffusion, color and opacity, not sure if all programs have occlusion, then there is specularity, Poser has radiosity (I know I am spelling that wrong), there is how intense a light is, the distance it reaches, whether or not you can use raytracing on it and in Daz there is deep shadow mapping.  When it comes to shiny things you also have reflection and refraction.


Now to use a tut from one program for another, you first need to know how all those buttons work and what altering them will do.  The two links below are for Daz and give quite a bit of information on lights, however, I have not been able to find one for Poser that even comes close to those two links when explaining lights.  So you need to think like me and try tuts made for a different program in your preferred one.


http://amandabb.com/daz-studio-tutorials/daz-studio-tutorial-4-adding-lights-and-rendering/


http://digilander.libero.it/maclean/DStutorial.htm


Now as to the SSS and Uber Lights, I have yet to see a tut that will allow someone to use the standard that come with a program that will produce the same effect as those two types.  They simply look really good.  On top of that, people in general can be lazy and impatient, I am guilty of that myself on occasion so those two types of lights make it easier to light your scene, then doing it from scratch.


To get even more in-depth, you also have HDR, HDRI, IBL and I think there is one more out there, to produce better lights.  The new toy for Daz is Reality Plugin.


Now when all is said and done, that is a lot of information to process and use and the lack of proper tuts make it harder.  Most tuts say they are for the beginner, yet are way to technical and don't give enough information and images to explain what they are talking about, especially when it comes to Poser.  People seem to be more interested in showing off what they did and not give out their secrets on how they got there.  An entire day at Deviant Art proved that.


I tried to find tuts like the two links above but for Poser and couldn't find any unless you wanted to download what could only be called a book about everything in the program, leaving one to hunt for the information, or to buy tutorials and since I would have to buy them to look and see if they are even worth the money, I could not post the links for them.

Reality - and now Luxus - are both something where you have to learn a totally different type of lighting, because they are sending the render to LuxRender, which is an unbiased render engine.
I just got Luxus last week (I don't like extra activations on single person webpages like Reality asks for, they seem to vanish quite often).
It's fun and interesting and a whole new world of rendering - and if you should stumble over tutorials for these, I would be happy to see them.
I know that less is more in the case of LuxRender, but that is all I know. LOL

So in short, Parkdale, when it comes to Poser, the only thing to consider from a basics standpoint, is which lights to add, how many and where to position them, the rest is done through the materials room (I hear groans as people read that...lol).  From past posts made here and elsewhere, many people are spooked by the material room.  I have seen a number of tuts regarding the material room and the images look like math equations on a chalk board, but in box form...lol...I can sympathize with them if they are new to it.


I have Poser 6, even had it installed and played with it a few times.  It is so different from Daz in the way it's set up and how you do things.


I have to find a way to post a tut in here that I got in an email, I tried to find it at the site but no luck.  It talks about using 4 lights, not 3 and is suppose to be so much better for your renders.  The tut was not program specific, so anyone can use it.

Oops forgot your question Kerya, I will see what I can do about tuts for those two programs, specifically Lux. It will take a bit cause I have to go out for a few hours and then update the sig tag showoff thread for Easter.

The no shadows thing drives me nuts. I think that is one reason I struggle with lights.

If you were using Daz I could help, however Poser makes me a complete dunce...lol  Parkdale has a stickied thread, it's near the top of the forum, about using lights, if you post there he could probably help you.

Ok Sanbie this thread is ready to be moved to a tutorial section.
