Flower Animation Part 1:    • Houdini Tutorial | Blooming Flowers | Mode...  
Flower Animation Part 2:    • Houdini Tutorial | Blooming Flowers | Mode...  

In the first two parts, we went over procedural modeling for a single petal, procedural rigging, and how to animate and deform a single petal. Then we distributed the single petal onto a phyllotaxis point setup and created a procedural animation system for the full flower.

In this part three of the Houdini flower tutorial series, we will make some final tweaks to this flower setup. The ultimate goal here is to add realistic flower petal detail and run the animation through a vellum simulation. This is the final part of setting up. You can use this setup to model flowers from reference or make up your own flower shapes.

Before getting to a vellum setup, we need to ensure that the flower is properly de-intersected, so no petals are overlapping.

Then I'll go over how KineFX motion clips can be used to sequence animations together, and I'll give a brief overview of my asset that does the same thing, only faster.

Once all of that is done, we will prepare the flower for the vellum simulation.

At the end, we'll do a few fixes and edits throughout the setup to finalize it.

In the next video, we will model a flower from reference using our now finished setup. Hopefully, we will also manage to shade and render using Karma and Solaris.

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.
