Textures with bump-mapping:

This is good for creating Details on objects. The key here is to know when to bump-map and when to actually model something instead. I'm going to use both and hopefully this will make it easier for you to decide when to do each. Texturing is a great way to add depth to things without complicated modeling however a mix of the two is often the answer. A good bump-map with a little extra modeling will go along ways. What were going to do in this example is add some simple snow objects. and then add a stencil bump-mapped texture to our buildings to look like there are more details. (As well as apply some texturing to our new snow objects)

Modeling instead of Texturing:

The first thing I did was to duplicate our ground and subdivide it a couple of times subdivide. (fract-subdivide is nice to) Then I moved some points around and made it a subsurface to smooth it out a bit. subdivided image
Next I duplicated our buildings and did the same thing. Along with that I slightly lifted the snow buildings and moved them slightly to one side and away from the camera. giving the new objects a new white material. I've rendered the buildings in wire frame so you can see a little better what's going on. snowobject

Texturing with Bump-Maps:

First I created a couple of images in the Gimp. Nothing Fancy but they will get the job done. I'm going to use one as a color channel and the second as a bump-map. The following table contains what the images look like and the material settings applied to both. (In the texture buttons all I did was make sure repeat was clicked.)

Next we will do the snow with the following texture properties. For this I have two cloud textures (listed first and then after that the material settings for each.

Things to try:

  • Use other things besides normal and alpha to apply textures to a material. To affect reflections as well as other surface properties.
  • Use more complicated Images so it doesn't look like a cookie cutter image.
