Blender 2.6 - Internal render - Interior design #2

2012-01-06T15:14:00.001+01:00

A few more images. The only diference between previous post and here is pretty much heavy compositing usage, as well expirementing with openEXR file formats.
Actually, it appears pretty much fun and easy to achieve this kind of images out of the internal render.

Blender 2.6 - Internal render - Interior design

2011-12-26T03:28:00.003+01:00

Hi! Well, i've been working on some interior projects on my own, most of them i'll include in interior tutorials that i'll start publishing soon, so i decided to share some tests of the images that i was experimenting on. I do planing to have more and more topics about blender internal render and it's capability of creating interors. Of course, i'll cover Cycles as well, and i have to say that even now, in early stages, i've done pretty heavy scene interiors, but for now, i do stuff with internal.

Images below are the node setups for the interiors.

Blender 2.6 - Cycles - Grass video tutorial

2011-12-21T14:17:00.004+01:00

Hi! Well, finally i got the chance to upload grass tutorial. I apologize for delay, but now you can take a look. The sound and my english aren't perfect, even i tried to make decent quality, but i think it's accpetable enough.

It is a bit longer than i expected, but i've tried to go slower just to make sure it is understandable. Now, i personaly prefer this way of creating grass, and one of the reasons for that, is pleasure that i can see the grass as it is in final render.

The other thing about the video, quality is a bit lower after i've upload it on youtube, and it's not that bad, but when i get the chance l'll replace it with the HD version.

So, enjoy! :)

Here is the .blend file if you need it as a guide or comparison:

http://www.sendspace.com/file/6biht4

Steps:

a) straw sample

b) grass sample

c) ground

d) applying grass as particles to the gournd

e) grass viewport preview

f) closer preview

g) test render

h) fullscreen test render

Blender 2.5 - Internal render - Exterior design - different techinques and approaches #01

2011-08-31T02:49:00.000+02:00

In the meantime, here are some images i've been keeping for some time, only experimentations with blender internal render. To atchieve some of the techinques below, it won't take more than 20-30 minutes of work, including whole work, meaning: modeling, texturing, rendering, compositing. :)

Have fun!

Blender 2.5 - Internal render - Interior tutorials 'sneak peak'

2011-08-31T00:09:00.001+02:00

Hi! I thought it's about time to reveal couple of things that i've been working on. To be precisely, interior tutorials! So, i ain't gonna talk to much now, i'll put away talking for later :) , but i hope you'll like it.

Btw, i'll try to cover what nodes or what order of nodes is needed to achive different moods in the images or similar stuff.

So, just a few words, and until tutorials see the daylight, have fun! All the best! :)

Blender 2.5 - Cycles - grass

2011-06-14T23:50:00.006+02:00

Can't do hair, yet, can do grass :)

As i noticed, grass is almost always done by 'hair' particle system. In cycles, for now, this ain't gonna work. Now, there is an alternative, instead of hair go with emitter (it worked for me).
Of course, this type of grass can be used in other render engines. And i think that this is a better way to achieve realism.

Really simple actually. You start with one simple stalk, and one simple stalk texture, and do UV stuff that goes with it.

Then, duplicate that stalk few times, and do some variations with all of them.

Now, create one plane, and apply particle system. Within emission parameter, set number of copies. If you are rendering frame 1, set start to -5 and end to -4. Lifetime... just put some big number.

Display - if your computer is slow, reduce diplay number.

In render settings, choose object and instead of particles select your group of stalks.

In physics, set it to NO, size to 1, random size to 0.500

It should be like in an image below.

...or texture preview.

...aaaaand i put same grass material, really basic.

...aaaaand played a bit with some compositing nodes...

That's it. I hope you'll find this useful!

I'll upload video tutorial of this in a next few days (if this is a little confusing).

Now you can watch video tutorial as well. You can watch tutorial here or on youtube.

Blender 2.5 - Cycles - Black dots

2011-06-07T11:12:00.004+02:00

Ok, here's the thing, i tried in many ways to see why and when those dots appearing. So i made a few scenes similar to the parts of Alex's scene, and, you can say that lighting is causing the problem, but i guess material too should be controled, as well objects intersetcions.

a) Image with dots (100 passes)

b) comparing with material differences

Now, if object (light), is intersecting with another object (with velvet material, as it is in my case), result will be like in an image above, dots start to apearing. If you try to change materials or recalculate normals...nope, same thing happening. So i drag those light's a little higher, to make some distance between lights and regular objects, and render it again, dots disappeared.

c) comparing

d) no dots (100 passes)

So, i think this might be solution, if it's not, please send me a comment, and we'll try again.

Blender 2.5 - Cycles - Citroen DS

2011-06-02T23:04:00.004+02:00

After speed modeling comes quick render. And still experimentations with Cycles. Whole work was one day job, so it isn't perfect, but results i really like.

Blender 2.5 - speed modeling - Citroen DS

2011-06-01T22:32:00.000+02:00

Actually, i've only wanted to work on renderings. But then, i decided (for a change) to record my workflow. So, here is only modeling. Reference images i used in this recording are from the-blueprints.com, and other images i've found on google. It's a bit faster than i wanted to be, but i hope you'll see how i worked on it. Have fun!

Blender 2.5 - 'Align selected to active'

2011-05-30T08:43:00.000+02:00

Quick tip along with a tip that i learned from the blenderartist.org.

Example of how to apply 'align selected to active' feature

- Load start up scene, than select camera.

- Next, press SHIFT + S and choose 'cursor to selected'

- Add a plane...

- Now, for this feature to work, select plane, press SHIFT and select camera. And from the object menu, transform > align selected to active

- Plane should be oriented the same way as camera. That's it. :)

- And for the other tip. Select plane, go in edit mode, and add two loops in both directions. Than, CTRL + TAB + 3 (to choose 'face select mode'), select face in the middle, X and delete it.

- Press TAB to exit 'edit mode', ALT + SPACE and select 'local' coordinate, and move plane downward along the Z axis just a little.

- Keep the plane selected, press 0 on numpad, and from camea view scale the plane and try matching it with boundaries. While it is selected, make it diffuse black or any color you like.

That's it, now if you render this, you get something like in an image below

In the camera settings, set lens radius to 0.03.

If you want to see more of how to achieve the effect in the image above, take a look in here

Have fun!

Blender 2.5 - Cycles - Dirty surfaces

2011-05-27T16:46:00.001+02:00

Ok, a lttle dirt now. It took me some time to figure out this, and i will go straigh to the point...

- You need two objects in the scene for this tutorial, a plane and some extended cube...

- And few textures (i found somethnig on google)

image A

image B

- Because image A has to be transparent, it requires some change. Something similar to an image below...

- Next, make box diffuse color yellow...

- Select plane, press TAB, press U and choose unwrap...

- Now, node editor. Make sure that there is material output node.

- Add mix closure node, and connect to the surface.

- Add diffuse node, and connect it to the colsure1.

- Add image texture node...

- And put in image A. It should apear into closure1 image settings

- Connect image coordinate node with image texture node.

- Now, closure2. Connect in this order, glossy node, image texture, and texture coordinate.

- Here you can put image B

- Or it looks something like this

- And when you render it...

Have fun!

Blender 2.5 - Cycles - alpha channel

2011-05-26T20:53:00.001+02:00

Quick and easy tip (now when i now it), just few steps to know when you using alpha.

- First thing you need, is an image (jpg), with black and white colors or any in between, where dark colors are for materials with no transparentcy and white for transparent material.

- In Blender, create three planes, one above other.

- Than add textures to them...

- For the bottom plane, add difuse material

- For the top plane, add 'emission' node

- And for the middle plane, a bit more. Add 'transparent BSDF' node, than 'image texture' and 'Texture coordinate' node, 'image texture' connected wtih 'uv', in order like in image below.

- Now, select middle plane, press U and from the menu choose 'unwrap'. Than, under the 'suface' parameters, locate an image. Basically, that's all for the alpha channel.

- And in the end, you get something similar to an image below.

Blender 2.5 - Cycles - HDRI - enviroment texture

2011-05-26T13:05:00.001+02:00

There are few simple steps for seting up hdri images or any diferent format as an 'enviroment texture' within Cycles. Yet, there's one thing i couldn't find, exposure control for hdri (or i just don't see it). But, there is something similar...
- First thnig first, put some scene into viewport...

- Now, 'world' panel. 'Surface' settings should set to 'none'.

- Now we'll work from the 'node editor'.

- Make shure there is 'world output' node.
- Add 'baskground' node, and connect it to the 'surface' within 'world output' node.

- Now if we make a preview, we'll see white background.

- In the 'node editor' add 'enviroment texture' node.

- Than locate an image (hdri or any other), if you don't have it google it :)

- Make a preview...

- If the scene is to dark just increase strenght of the background

- If you want a bit more control, you can add 'Mapping' node and 'Texture coordinate' node, than it's posible to rotate, translate and scale background image.

This is a simplest way i managed to put hdri (in this case bmp), but, it probably would be better if there is exposure control. Anyway, 'Cycles' is in early stage of development, it is powerful enough already.

Blender 2.5 - Cycles - Infinite plane

2011-05-25T18:19:00.000+02:00

Quite easy to achieve. Just a combination of two nodes, where the second one is always 'Transparent BSDF'. I needed something like this for my industrial purposes, and this is what i came up with... easier couldn't be :)

node setup

-First thing you need is 'mix closure' node,

-Second, connect 'fresnel' node with 'fac' within 'mix closure node', you can setup value as you like (more or less visible primary material),

-than, add primary material and connect it to 'closure1',

-add 'transparent BSDF' and connect it to 'closure2',

and that's it. :)

It looks something like image below.

Just an experimentation...

Interior design - ideas #2

2011-04-16T18:47:00.000+02:00

It's one of my older works, actually not too old, but here it is. The issue with this apartment was huge space but too many walls, therefore the entire apartmnet wasn't very suitable for everyday life. So, images below shows main room, made from three separated rooms, plus kitchen (it's not final result, but rather preview of close to finished work).
And just to mention that the images were created in blender 2.56.

Rose modeling - Blender 2.5 tutorial

2011-02-21T04:08:00.000+01:00

At least it looks like rose, anyway, i hope you'll find this tutorial useful.
By the way, set the 480p for better quality.

3ds max - Setting up reference images

2011-01-24T21:18:00.000+01:00

Well, there are so many video tutorials about setting up reference images, and most of them are just WRONG. When you get an image with 3 or 4 ortographic views, you do NOT CUT IT into pieces, and for every view use diferent material slots. It is much easier to use one image and one material slot for all views.
I hope you'll find this tut useful.

Lamborghini Gallardo

2010-09-01T10:14:00.000+02:00

I'll consider this as an opening for my few-days-ago created blog.
I've spent just few hours working on this, so there's no much details to talk about. It is done in blender 2.53, with a little gimp help...
A week ago i've began using blender 2.53, so.. this is more like testing. A few weeks ago i've started in blender 2.49... and i must say, i was astound by it's power. Now, blender is my new major software.
I'm almost ten years in 3d... thing, in case if you ask yourself how i learned blender so fast.
I hope you'll enjoy this photos, and maybe in the future we share some technics. I'm new in blender, so please, don't be too hard with critics.
btw.. sorry for bad english (i'm learning that too).
In the end, to say something about me.. i'm Igor, from Serbia, artist, (more) industrial and (less) graphic designer, musician (guitarist)... and other.. stuff...
