Bongo's environment 2

The World options
|
|
And now go to the World window... add a new world, rename it "Bongo World" and set it this way:
|
|
|
With the add of the Mist button we can fake the heavy underwater perspective; the far objects will be the
closest to the background colour we set in the World option.
As you can see, I set the AmbR, AmbG and AmbB values to a lighter version of the background color (the HorR, HorG and HorB values); this will affect the "ambient" color of the objects in the scene. And now a trick: often computer generated images looks fake because of their perfectly clean quality. So, in the texture slots of the World window, we load some procedural texture to "dirt" the background. The more important one is Clouds (in the third slot), set to NoiseSize = 0.600, NoiseDepth = 6 and Hard noise selected, but two Blend Linear will improve the quality of the underwater effect: set the first Blend To Blend, ZenUp, ZenDo; for the second Blend select only the Stencil button and for the Clouds set to Blend and ZenUp (if you don't clearly understand this, have a look at the image above...). This way the Stencil Blend in the second slot will act as a filter for the visibility of the last Clouds texture. |

The light's rays
|
|
One important improvement in such a scene is the simulation of rays of light passing through the water's surface;
well, this is really simple to do!
Add a Tube primitive to the scene (in a different layer, of course) and scale it in edit mode to obtain the right shape similar to a paper funnel. Then go to the Material window and add a new material. Load two procedural Blends, the first Lin and the second Sphere: for this one select the Colorband button, hence the E (Interpolation type Easy) mode. Here you can see the complete setting: |
|
|
The light ray is ready; we can duplicate it with SHIFT-D and put several scaled copies around the set (as you can
see in the header near the material name in the above image, I made this 14 times).
