Budokai 1 Shaders edits
Depending what shaders values you use, you can obtain very different results.
In the game, every characters use the same lighting value : And this is why the characters who are transformed in Super Saiyans have the same luminosity and shadows as normal characters.
While I'm at it, it is also possible to change how the base form of the characters look like and give them a shading similar to the one which is used in the Raging Blast series.
