When I ray trace my image the water in my plan looks like glass. How can I make it look like water with different ripple effects?
The traditional way of creating water using a texture image can create some great looking images, however, in Chief Architect, there is even more power available in using bump maps.
On the right side of this image we have created our pool and applied a generic water material from the Core Catalog. The resulting ray trace reveals a glass-like surface on the water, so the reflection on the surface is unchanged.
On the left side of the image the same water material is used, but a bump map has been applied. Notice the ripples in the surface and the distorted reflection.
Bump maps are simply images that are layered under the face, created by the original material, and the program uses the dark and light areas in the bump map to simulate changes in the surface of the model.
In this example, we will illustrate how applying a bump map can greatly increase the quality and realism of the swimming pool.
As the bump map is increased in size the height multiplier is reduced to keep the waves from being too tall.
If you want a more agitated looking pool, then simply increase the height multiplier or decrease the Ratio.
Trying different combinations will give you a feel for how the material of your choice interacts with the bump map.
The result should apply a wavy pattern to the surface of the water distorting the objects beneath the surface.
