Weekend - Update Time

Allright, ready to start working on this again. I'll update the tutorial with node network shots and example images and start with the second part.

cheers...

Tutorial - Basic Texturing

Basic texturing and object/population distribution

Part I - Texturing


So, you've got a terrain, it's all grey and somehow you don't get it managed to apply any colours? Then here's the place to read on.

First, we're going to add a 'surface layer'(sl) under the 'shaders' tab. Or, if you want to use the node-network,
right-click->create shader->other surface shader->surface layer.
Then connect the base colours output into the input of the surface layer and the sl's output into the terrain input of your planet.


Now everything (except for the sky :) ) in your preview window should look white.
Because that's more boring than we had before, we're actually going to add colours now, yeah :)
(Just keep in mind, the white layer appearance is quite usefull when we need to restrict that layer to a specific heigth/slope range - visibility!!!)


Allright, then to the colours. We'll be using powerfractal shaders for now, as you keep experimenting you will find other ways of colouring too.
Powerfractals are giving us just that, a fractal noise, which can be adjusted in colour/scale/kind of noise/etc. Diving into that too deep would be too much for now i guess, and a major part about the fun behind terragen 2 is the experiments.


Good, now let's actually add one of those beasts. In the node network view, in the shaders group (that's where your surface layer should be) press
right-click->create shader->colour shader->power fractal shader v3.

If you are using the navigation tabs: goto shaders, select your surface layer and press
'add child layer'->surface shaders->colour shaders->power fractal shader v3.

Now we'll take the powerfractals (pf) output and let it go into the surface layers 'colour function' input. Voila, the white layer in your preview window should look grey now. 2 steps forward, 1 step back, huh? :)


The fun part: going crazy with those colours.
Double-click the powerfractal node in the node network view. That brings up it's settings. On the first tab you see the settings to adjust the scale of your pf, you can do it right now, just to get a first feeling for it.

The second tab is what we're looking after now, the colours tab.
First, click the checkbox saying 'apply low colour'. Now we've set the colour range from 0=black to 1=white. You can change the colours now by just pressing
the colour buttons next to the sliders. Take anything you want to use for your scene, after all, it's YOUR scene :D

Adjust the other settings to your likage (keep experimenting!), go to the renderers tab and perform a quick render.

To see what just 1 powerfractal can look like, check out my image 'The power of GI', the bigger planet's surface was made from 1 surface layer and 1 pf.

Windwheel aged

Messed around a bit with the windwheel model posted by Kranky on Planetside's Filesharing Section.

Decided that i wanted it to look somewhat older, so i applied rust to the model ( 2 versions, 1 is an image map driven by an extra projection camera). I added a smooth displacement to the metal and wooden parts aswell, enjoy ( click ).

The power of GI

This image was made out of curiosity, i wanted to see how far we could go using a luminescent surface layer.
Turned out quite good, no additional sun was used in this scene, all the light is comming from the bigger planet.

Welcome!

Hi everyone,

so i decided to make my own Blog now, how nerdy :P

The subject will be Terragen2, the famous 3D landscape generator (well, more than just that, actually), i'll be putting up some scenes but most will be results from my experiments.
In addition i'll just post anything that might come handy, tgd's, clip files, masks, just links to ressources, whatever just comes in my mind.

So, have fun (and be patient, first blog/homepage ever :D)

cheers...
