I completed one where Mikael Pettersen demonstrates how to create a Blendshape crowd agent.

I completed an asteroid generator tutorial. This one has my modified way of restoring UVs after modeling. Hires and LoRes output options are available. Two modeling operations are performed, the VDB method, which destroys UVs, and the mesh boolean operation which preserves them. After converting the VDB back to polygons and polyreducing, the UVs from the boolean mesh are transferred to the resulting surfaces.

I just worked through the fake inflate/squeeze tutorial. It's not as robust as a vellum solution, but if you just need a still, this modeling technique might work for you.

I worked through the suspended dust tutorial. This effect can be found in almost every streaming show.

I worked my way through Edmond's tutorial on how to allow flip droplet particles to escape their boundary. The nodes modified inside of the unlocked HDAs are marked in RED.

Here is SquidBean's setup for using TOPs to export each agent as a single animated FBX. You can drag the resulting set of FBX files into Unreal. This approach avoids Alembic geometry caches, which can get quite large. It also presents a true skeleton to Unreal for internal processing.

I worked through the spin particles tutorial. The thumbnail looks nothing like the tutorial result. I don't understand why authors do that? This file demonstrates how to make randomly rotating particles lie flat after contact. This technique can be used with RBD debris as well.
