UnityFishAnimation

A vertex shader for fish animation

Right now, the light model is a simple toon shading and mesh color(you can replace it with main texture of course). In my project, I use toon shading and mesh color to dynamic batching as many mesh as possible. since I usually got a lot of fish on the scene.

How To Use

• Create new material with -> Custom/ToonMovingFish shader.

• Toggle on the DEBUG_COLOR_MASK option in the material inspector.

• Adjust _InvertScale for each model (usually a small model will require larger invertScale)

• Adjust _MaskZ to mask out the vertex animation strength. The animation strength will scale with the debug color on the mesh.(scale from black(0) to white(1)).

• Toogle on different animation option like SpinRoll, Side to side movement...etc

• Make sure the frequence are all the same for more nature movement.
