Youtube Description:
CHAPTER INDEX:
00:00:00 Intro
00:00:40 Creating Fluid Particles within a Shell or a Volume
00:01:56 Creating source points within a volume
00:02:56 Use Normal as Speed
00:08:00 Use attribute transfer to copy Normals to points generated by a VDB
00:12:05 Visualize velocities via Volume Slice and Volume Trails
00:14:32 Use Pyro source for point creation on surface OR a withing volume
00:16:52 Tipp: Particle scale
I'll explain different ways of creating points on surfaces, in volumes and how to use the Normal of the base-sphere as base-velocity for the volume sourcing.
