In this part, we go through some basics of procedural modeling and KineFX to create a single flower petal with a rig that allows the user to shape and animate between a “bud pose“ and a “bloom pose“. I attempted to keep this relatively beginner friendly, and if you treat the VEX wrangles as black boxes, everything else should be easy enough to follow. In the next parts of this series, we will make a phyllotaxis point generator to copy the petals onto, create a system for blending multiple skeletons based on a growth attribute, create procedural animation curves, and simulate the flower in Vellum. At some point throughout the series, we'll talk about using this procedural setup to model a flower and its growth animation based on photo reference. At the end of it all, we will make flower materials, light, and render the flower animation through Solaris using Karma. These methods are a mix of things I have seen from John Kunz on Patreon, Entagma, and some things I figured out together with Simon Reher.

Would be happy to see any flowers people create.
