Question Rendering help, please?

I'm pretty new to Blender, I can model a few things easily, but my problem is rendering. The main page on the Blender website has a render of a creature, I would like to know how to make a render that looks as realistic as that, thanks in advance.

I guess that you are refering to

I don't pretend to know as much as @ndy, but there isn't nothing particullary special. It is a combination of 3 elements.

a.- Superb modeling.
b.- Extremly well executed shader (both material composition and mapping).
c.- Lighting, lighting, lighting and more lighting.

Snog is wearing a double layer skin, a transparent and very shinny one plus a hand painted color map with translucency and bump mapping activated. But it is the lighting the real protagonist of that picture.

On top of all there is a post-processing glow filter and a very pronounced DOF effect. Those could be the ones built into Blender, or from post-processing on a tird party application.

All I can say is that doing something like Snog takes a lot of patience and expertice.. i.e., I' ve never been able to create eyes textures as good as the one you see here, and I've tryed and tryed and tryed. Each time I get better, but there is still a long road ahead of me when it comes to hand painted textures.

Good Luck!

there are people not that new to blender and despite their knowledge on HOW to make it, not everybody can get there.

A) learn how to set up lights lighting
b) learn how to apply multiple textures
c) get confortable with uv-mapping

if you use the fat written in the searchfunction of elysiun or here( specially on lighting a scene u will find a LOT of information in CGTalk.Head over to the rendering threads and u will get cool links and advice on how to set up light in your scene.)

have fun

btw. in my opinion the right light setting is harder to learn than to model. With the wrong lighting even with the best texturers u can ruin a scene completely.

Question

Okay, I searched for lighting and I also searched for rendering, but I couldn't fine anything about light setup. Can someone show me a specific thread for light/render setup?

i think everything is said by appolux and bbirras.
blender is pretty much like any other 3d app out there, it takes some time to get comfortable with and of course it needs a lot of practising to produce something 'a bit more elaborate'.
dont give up, practise, learn.

just to show you that there's no mystery behind my snog image:

@ndy that is a great picture! Without looking at your scene shot I would've never guessed you used so many lights.

Double surprize for me

1.- @ndy has been seating quietly here at the Blender forum over CGTalk !!!!!!
2.- I was imaging that scene with a least twice the lights that you actually used

hehehe
what it does not show are the hours @ndy must have spend on the texturing!!!!! and the right set-up, test renderings etc..lighing, re-lighting...blabalbala
in short: any strait forward scene, can be converted into something special.

just compare the first testrender, with the blender materials and the final pic in apollux-post with the textures....
there are 2 worlds in between

conclusion:
none.....Is it easy once u know how to do it?....NO its not....it just takes patience, practice&skill, lots of coffee and a lost sense of time (kennst de das irgendwoher,hab ich ~ von dir geklaut,hehehe)

@ndy, if you're still here, could you tell me the specs for some of the lights? I don't know how many samples to use and all of that (I don't even know what half of these settings are, lol.) I'd appreciate it, thank you.

i'm here! i'm here all the time!
you're on the save side with an energy value from 1 - 2 [if you have more than 3 lights in the scene... but it really depends]
i usually use the max sample amount for shadowmapped spots [16] and a buffer size from 1024 to 2056... adjust the clipSta and clipEnd according to the scene and set the bias a bit lower.

you shouldnt use me as a reference tho :P
read the manual, read tutorials and then you'll find your own settings!

Thanks @ndy!

I know I shouldn't use you as a reference, but that render/light setup is so darn good! I've tried and tried to find tutorials to help me understand blender terms, but it's no use, I'm still a blender n00b, lol.
