How to make a Landscape

Simple Guidline for Landscapes    
  2. Relief Object    
Now we will do a landscape with a bitmap. The following example uses Bodypaint, because it has some workflow advantages. If you work with a program other than BodyPaint you may adopt the steps shown.

First create a new texture. In this case we use the standard settings of BP.
The result should be a black picture. Because of the layertechnique you can choose to paint on selveral different layers. That might help you to add or change things with a better control.
Now try to draw a figure like the one on the right. I used the standard Brush 'Lighten' at 50% size and 10% pressure, guess this is the standard setting. I used a 'white' color with 30% brightness. Yes I know it's pretty hard to see, but if we use white, we might get problems if we change something.
Save the picture as land-1.psd within your model folder or within the tex folder below your model folder.
Next switch to C4d editor and make a new Relief Object. Open it and click at the 'Image' button and choose the file land-1.psd. If you render your picture you'll should get something similar. I used a light with hard shadows for that picture.
If you change the Segment settings from 100 to 600 you'll get something like the one on the right. Not only the bitmap gets a higher resolution, but also notice the shadow! In addition I changed the height from 100 to 200. You can vary the parameter for segment to feel comfortable with the speed.
Now place a camera, similar to the one in the picture. Then we will change the bitmap a little bit.
If you compare this bitmap with the first one, you'll see that there are some additional white areas, well not really white but brighter. Make a new layer and try it too. The 'Lighten Brush was used with 5% pressure and 40% size. With a gray color at 60% brightness.
And this is what it looks like in the editor window. Looks funny, doesn't it. But keep in mind that this look depends on the number of Segments you have!.
Note: If you use Bodypaint it's impossible to draw directly in the editor view, but if you open the Relief Object and close it with OK. Your new bitmap is used. Please use a b3d file for this.

Next change. Here you can see the part close to the camera. I turned off the background layer so you can see what the brush named 'Chalk' did (hopefully you can, if you click the picture). From the upper right to the lower left I varied the pressure and size of the brush.
You can see all those little dots from the 'Chalk' Brush. And you will also notice that I used a dark color to 'burn' wholes into the gray background.
This picture shows the location of the obove but it has also dots in the middle part.

Please use layers if you can. At least you will have three advantages. First you can throw it away if you don't like it. Second you will not destroy the things you did, third you are able to give your layers a transparency and therefore you will have a greater control.

Oh, I forgot, there is a forth reason. You may combine the layers in a different way.


And this is how it looks like with the small dots. You may notice the little shadow distortion. Now it comes to the point to take a closer look at the segment resolution and may be the layer combination. The little dots layer will be combined with the rest (background) of the bitmap.

Now let your toughts free. You don't need more than 5 Minutes to create all this landscapes.
Ups, sorry I accidentially turned off the background. What you see is the checkerbox that is not only visible with bodypaint :))
Just two clicks of chalk. That's just it.
And some more chalk.
One last word, you should always keep in mind that the difference between black and white is the lowest and highest point. Everything between has to be some gray.
