This talk is about applying AAA pixel animation techniques to mobile games. A pipeline using tools such as FluidNinjia, Amplified Shader Editor, Unreal Niagara, and Unity 3D to create pixel animation for UIs, visual effects, and environments. I will discuss how to create pixel animations using a particle system, a bitmap, or a vector field. The presentation will also explain the math behind the shaders with algorithms, graphs, and animated images. Nodes and terms such as velocity, Fmod, sine, floor, fract, linear interpolation, etc. have never been presented in so vividly. The sample VFX used in the talk illustrates the connection been texture coordinates,pixel world position and image channels. VFX artists, UI artists, environment artists, and motion picture designers will learn a quick and efficient way to create pixel animation effects for games, movies, ad, etc.

Takeaway

FluidNinjia, Unreal, ASE and Unity can be combined to create pixel animations for VFX, UI, enviroments.
Particle system, bitmap, and vector field can be used to create pixel animation in FluidNinjia.
The principle of pixel animation is this: the middle gray of a flow-map represents no movement. Black moves in one direction, and white moves in the opposite direction.

Intended Audience

VFX, UI, environment, technical, motion picture designers, art students, programmers, and math lovers will learn making pixel animation technique from this talk. Some knowledge of shader editing helps.
