scene_read

Read FX scene source

Read a saved scene's source verbatim, its revision/hash, settings and version history before editing. Omit project_id for your account. Optional revision reads a retained version; restoring means writing that source as a new revision using the current guards. Optional line bounds limit a large read. Edit matching is literal, including whitespace; no regular-expression replacement expansion occurs.
