i did this picture for a school project i made it black and white just to try something new
IPB Image
i used 6 lights total(5 to light the model and 1 for the lensflare)i set all the samples to 5 or 10
and set the photons cast to 20000
also for the bark i used "dark tree"
the black and white every thing turned realy well(just so every one can know my monotor is old so my screen is darker than every one elses.there might be a slight diffrence in detail)

Wild!

Looks like we have light coming from this side too.
The backdrop is a painting right?
Is that a hedge underneath?
Cookie cut leaves?

Oh, so many questions.
This is very interesting.

I love the bare branches,
like a tree burned nearly to ashes.

1 the light is coming from all directions
2 no its not a painting i used the sine combiner to make the cloud look(i can't pain't at all)
3 nope not a cookie cut i used the time line to make the wierd grass and the grass is also made so that
--its white at the botom fo the grass and black at the top also using the time line.
4 um this is sorta a noob queston i might already know just never realy call it that whats a hedge?
5 yes that is exactly what i was aiming for
6 plus the rendering time for it was pretty short it took like 6 mins.
7 i take grate pride in this one
8 i used hp imaging to turn it fully black and white
9 not bad for a 14 year old huh?
10 last witch is better the one with the color light or the one thats completely black and white
IPB Image
i say the color one more uniqe
arkaos
not bad 4 a 14 yr old, indeed, Mage. Nice pic and welcome to the fold.
the_black_mage
thx!and to think i did all this mainly by fooling around with it lol.i just wish my mom gave me more credit...any at least i know that there are profetional people out there that know i'm good^_^.sad thing is i did this for a poetry project and i hate poetry.this isn't gonna end up an A+ project maybe C(i'm much of the reading type unless i'm super interested.).
<--now all i gotta do is make one of my favorite final fantasy characters VIVI.but i'll wait till my modeling skills are better.i got rendering down but modeling is still a problem, my personal rating of my self modeling from scatch(no plugins)3/5.but then a again i've only been using A:M for like a year and a half(more like a year we were moving,i had no co,mputer for months!)

6 lights and photons? All this render time lost for nothing. Using any sort of light rigs other than natural positioning of lights along with radiosity defeats the whole purpose of radiosity.

Why did you decide to use radiosity in this render?
the_black_mage
i wanted to use it realy badly so i thought i'd try out raidiosity, and like i said i was gooffing around with it trying ot get a cool look to it.tried one light..well 2(lens flare)but it didn't realy look that good,it was to dark.and when i renderd it with no raidiosity(and the 6 lights) the effects were similar but the lens flare affects where completely wrong.so i used multiples,turned on radiosity set the settings,then i got this.

That is definitely not a good reason to turn ON radiosity. Radiosity is not something you just turn ON. You need to know what it is doing to your scene before you decide to use it. Right now, even though you turned it ON, there are no noticeable radiosity effect in your render at all. So you are just spending CPU time for nothing.

If it was too dark with radiosity and one light, that is because you setup your scene wrong. probably didn't setup your scene in a closed environment or your mateiral were setup with some missing properties like no or little radiance or some additional unnecessary properties like ambiance.

A Radiosity scene is much harder to setup than normal raytrace lit scene. To setup a radiosity scene, you need to understand how light and material work and interact together. It's not like setting up a raytrace scene where you can get decent result without lighting knowledge but rather just by trial and error and adding lights. That is because a ratraced scene gives you exactly what you setup as light in a scene nothing more. What you see is what you get. There are no other lights in a raytraced scene except those you placed. While radiosity also takes into account indirect lighting. So it needs to have something to indirectly reflect light and those surfaces needs to be setup in a ralistic way.

First, you need to understand what indirect light is and where it comes from. Check the Itchy Animation Light tutorial for a good introduction on that. Then you also need to follow all the rules as given in the Cornell Box tutorial for radiosity scenes.

and when i renderd it with no raidiosity(and the 6 lights) the effects were similar but the lens flare affects where completely wrong.so i used multiples,turned on radiosity set the settings,then i got this.

If the renders were similar with and without radiosity, then that is a sure indication that you used radiosity wrong and gained nothing from its use except way longer render times.

Radiosity have nothing to do with lens flares because Lens flares are post processed effects based on light positions and intensities. If the lesn flares did change after you turned radiosity ON, it is most probably because you did some other changes at the same time.

hmmmmm...mabe your right.i could have made changes.you know what i'll change the setting change lights and every thng and seee if i can make this better.and i didn't know about those sites thx.
the_black_mage
sorry i took so long but i had to wait till my mom bought a new monitor.you see i discoverd my monotor is way to dark to do any raidiosity test.i can't post the picture now,but later its rendering.(2hours later)well actualy i just started rendering it and it might be a while so i'll post later,someware like an hour.
