Freeze

Method #

This node freezes the parent mesh at its current state in the deform stack. Once frozen and until the node ends or is disabled, the frozen copy of the mesh is used instead of running the proceeding part of the deformer stack on updates. This means that the parent mesh will no longer change due to any deformers or animation that run before the freeze node in the stack. This can also provide a sizeable performance benefit if the previous nodes in the deformer stack were computationally intensive.

The freeze node clears every time the timeline is reset, so the full deform stack will run on the first execution after a reset. If there were changes to the nodes in the stack, this means that resetting the timeline will cause the frozen mesh to change. However, the node may also optionally cache the result to disk. If this is the case, the cached copy is used when the timeline is reset or when the project is loaded - so the full deform stack is never run, and the mesh is frozen permanently.
