Underwater scenes        By Ian Dale I've gotten over two dozen letters in one week asking me how I did the water surface and caustic lighting effects in my "School of Fish" image. So I've decided to write a tutorial to help everybody achieve these seemingly difficult effects. Here is the finished image. It is a spruced up version of the November runner-up in the Caligari trueSpace Image Gallery. The image is of sharks and pilot fish swimming down the hallway in my submerged high school. In this tutorial I will explain how I did the water ceiling and the caustic shadows on the sea floor.   (click on the image to see a larger version) First, just a quick overview of the scene: After creating the hallway as it is in real life, I removed the floor and replaced it with a squashed landscape made with the Landmaker plug-in. The sharks were made with metaballs for the body and polygon tools for the fins. The fish were sculpted with lattice deformations All the texture maps were painted in Photoshop   Next Page
