Houdini Flip Melt

Recently I've been obsessed with melting statues. Seemed like a fun way to get to grips with flip in Houdini. Here are few of the results. Out of the box there are some issues melting Rigid shapes, the main one is the amount of detail in the original mesh never really transfers through the vdb, particle, and then remesh workflow. To help this I calculated the nearest position to the start mesh for every flip particle, then transfer that data back to the remeshed fluid surface. Using that I could snap the new mesh to the old, and blend to the fluid by distance etc. Works pretty well in the end. Using the nearest surface XYZ distance was sufficient, but it could be expanded more to use a raycast approach in the future.
