Blender Export

Export only from the approved sceneRevision + snapshotId and under an approved output root. Existing files require action-bound overwrite authorization.

In auto_with_budget, export.file may write a new file in an allowed format under the session's approved root, using the current committed snapshot, without another user prompt. review_only rejects export even with a claim. Following user takeover, inspect again and create a new transaction/snapshot; old approvals must not be reused.

Call export.file; verify existence, non-zero size, SHA-256, format, and receipt schema. Model formats require isolated re-import validation; images and MP4 require media probing. Distinguish local export success from any downstream rendering system.

Use export.extended for EXR, USD/USDC and Alembic and preserve its receiptVersion 2.0.0 instead of rewriting it as the legacy receipt. For a long EXPORT or RENDER_STILL, use blender-background-jobs; export.file itself remains synchronous. Do not promise that pause interrupts an already-running synchronous export.
