I want to learn Blender...

I have 2 weeks already since i installed Blender for the first time.
Now, i am not ignorant when it comes to drawing, i am using Photoshop for many years already. I learned Wings3D too...
But Blender... Blender is impossibly hard. I love it is complex, but its (as i said before) IMPOSSIBLY complex!

As an example, ill show you 2 links with 2 pictures i made in Bryce in half an hour and rendered in 2 hours... the cracked egg is made in (I SWEAR ITS TRUE) less than 5 minutes. The chess was in half an hour.

Isnt there any PRE-seting for Glass, Metal, Skin, Rock... things, in Blender? Please, i want to learn Blender. I downloaded and downloaded and searched and searched... All i saw was gingerbread human models, basic modelling, cartoon like hats with no materials, a dice, quickie render, quickie models, very very simple things... I dont want to offend the people who did this, if it werent for this tutorials, i was even more noob than i am now!... I also dont expect to become proficient in one day, Photoshop took me months, BUT some presets for basic materials would SURELY help... it not as FILES, at least as a LIST with some values for reflection, Raymir, Fresnel, Zoffs, ZTransp, Ray Transp, IOR, Fac... and all that impossible to read and/ or understand stuff...

Thank you.
Once again, i dont want to offend the creators of those simple tutorials, but when i see the rendered stuff from the gallery of Blender... it creeps me out. I thought i am goot at graphics.

(Edited) PS: If i learn how to use Blender PROPERLY (this is a subjective oppinion) i promise to help the community by posting in Wiki and making tutorials.

Easy glass, turn on the raytracer ("Ray") in the render settings (F10), and in materials (F5) set alpha to 0.2 or something, and turn on "RayTransp" in the MirrorTransp window. You might also to increase the IOR value a bit to get refraction.

Seriously though, blender isnt about doing things for you. Spend a bit of time playing with the material settings and you will get the hang of it pretty quickly. Only important thing to know is that ZTransp uses the Zbuffer to apply transparency whereas RayTransp uses raytracing, so the two do pretty much the same thing in different ways. Anything beggining with Z is the zbuffer, Ray is the raytracer.

Have a look at this, and visit http://www.elysiun.com for user specific questions (this is more of a dev forum)

Hi Prahaai

There are a lot of good tuts out there, but without a good learning sequence, it's like a lot of hit and miss. Here's something I wrote for my classroom (and in the process of re-writing now)

maybe it can help

Ok

The help files for Blender, i'm talking about the official site, are quite spread... I downloaded the official help manual, Blender 2.3 Guide (Vol I - User) and Blender 2.3 Guide (Vol II - Reference) and a few movies and i discovered RIGHT NOW, while i was trying to explain you what i have that there are some templates, materials and textures on the official site! Very weird.

Thank you very much for the help.

Glass again

Me again.
Ok, i want to make glass again. I managed to make some transparent things, very ugly and very not-realistic.
This is the glass i made with blender.
http://www.geocities.com/tay_ka/Render/egg_blender.png

The first thing is the ugly reflection and transparency. The second thing, THE MOST IMPORTANT for me is the shadow, that must be empty inside, like a pink hole inside the black shadow... pink, because belive it or not, the egg is very very pink... you just can't see it. Trust me, lol.
This is how it should look:

So, ho can i make shadow with a colored hole inside of it?

Transparent Shadows

Pleaaase!
I need to make transparent shadows with Blender...

How can i do it? The previous post explained what i need. I read a lot of tutorials, but none of them could help...
I want to make a 3D drop of water on a 3D leaf... The shadow of water must be transparent and the leaf is not reflective enough to trick an effect...
Please.

And because you are very "apassionato". http://www.blender3d.org/cms/Transparen ... 514.0.html. These are additional informations, but there are some settings and further links.

Have fun!!

Blender and video textures

I would like to make a room with 6 sides (4 walls, floor and ceiling) and put a video on each wall as a texture. Then I want to do a walkthough of that room with a camera path. Can anyone point me in the right direction on a tutorial to do such a thing? It doesn't have to be specifically Blender, but it would be nice!

There's no tutorial on that specifically, I think, however...

See the manual here for animated image or video textures.

Camera paths could be controlled through a curve in the IPO editor and by setting key frames.

A search on elysiun.com might help you find more specific solutions to some of the problems you may encounter, like using multiple materials on a cube, etc.

If you are unhappy with the results of normal blender glass you may want to try the Yafray plugin. I found it extremely easy to make realistic glass just messing around with it. My second week Blending I created several versions of a wine glass and put them as a background on my computer at work. I got comments. People couldn't tell they weren't real. I bet Yafray will get you the result your looking for.
