... or as geometry? If it's sent as a texture, would regular texture pre-load tricks work (like setting sculpt texture UUIDs as textures for hidden prim faces to make the client download the texture)?
This would help synchronize scripted 'morphs' through swapping sculpt textures.
Would a sculpt texture UUID downloaded as a regular texture be instantly usable by the client as a sculpt texture? I would think it would, it should all be based on the UUID, right. If applying it as a sculpt texture caused a re-fetch, that would negate this approach.
