Vellum Guide Geometry
sop Vellum Guide Geometry

Setup for a vellum simulation that follows a guiding geometry. This is useful when you want to blend a geometry into its final form, while taking into account self or external collisions.

Unfurling Flower Pod
sop Unfurling Flower Pod

Building up from the unfurling stem example, this snippet assembles the stems into a flower pod. The animation includes a rig attribute wrangle as the main control, and a kinefx secondary motion for extra livity.

Simple Petal
sop Simple Petal

A few nodes to create a basic petal shape, with common masks, deformation, and UVs. This should provide a good base layer of detail to feed into a vellum simulation.

Lops Transforms To Sops
sop Lops Transforms To Sops

Extract names and transforms from USD objects and apply it to point attributes in SOPs. This allows for rebuilding the same layout in SOPs. This could be useful for converting manual layout to point instances or efficiently importing layout from external application trough USD format.
