Apply Deltas to Geometry Cache

One shape change, stamped onto every frame of a geometry cache, so a fix you sculpt once follows the whole take.

Apply Deltas to Geometry Cache node

The Apply Deltas to Geometry Cache node

When to use it

One shape change, stamped onto every frame of a geometry cache, so a fix you sculpt once follows the whole take.

The output is a Streaming Cache pin, so it chains with Sculpt (deltas accumulate) and is persisted by feeding an Export node. Nothing is written to disk here.

How to use it

  1. 1

    Connect a streaming cache

    From Load Geometry Cache, Load Alembic File or Load USD File.

  2. 2

    Connect the rest Mesh and the edited Target

    The two must share vertex order.

Pins

Pin Type Description
StreamingCache Streaming Geometry Cache The cache to change. Every frame in it picks up the same edit.
Mesh Mesh The reference mesh before you sculpted it.
Target Mesh The same mesh after sculpting. Whatever moved between the two is what every frame gets, so the vertex counts have to match or the node errors and passes the cache straight through.
Pin Type Description
StreamingCache Streaming Geometry Cache Same cache, now with the edit folded into every frame. Chain another one of these on to stack a second fix.

Available in Mesh Morpher Graph and Mesh Morpher Studio.

Get Streaming Geometry Cache Frame node

The Get Streaming Geometry Cache Frame node

When to use it

Grabs one frame out of a streaming geometry cache as an ordinary mesh, so any static mesh node can work on a single moment of an animation. The archive opens once and stays open, so stepping frames costs one read each.

Per-frame sculpt deltas set upstream by Geometry Cache Sculpt are folded in automatically, so what you get is the edited frame rather than the raw archive sample.

Pins

Pin Type Description
StreamingCache Streaming Geometry Cache The cache to read from. The file stays on disk and is only opened when a frame is asked for.
Pin Type Description
Mesh Mesh The mesh at the frame you picked.

Settings

Setting Type Description
Frame Number Whole number Which frame to read. Past Max Frame Number the node errors rather than quietly handing you a different frame.
