A RECORDED SESSION

Every call, as it happened.

The MifBridge panel inside Unreal, and the MifBlender panel inside Blender, replaying real sessions. Each row is one command the AI sent and what came back. Switch between them with the tabs on the panel.

Three refusals, word for word

When the AI asks for something it may not do, MifBridge refuses and says why, so the AI can correct itself. These are copied from the sessions above, each message shortened where the panel shortens it.

What the AI asked forWhat came backWhat that tells the AI
set_cvar
· UE 5.7
REFUSED no console variable named 'mif.BridgeWriteMode'The AI tried to raise its own permission level through a console variable. There is no such switch: only a person can change the level, in the MifBridge panel or when starting the editor.
import_asset
· UE 5.7
BLOCKED 'import_asset' is refused: the MifBridge safety gate is in 'scratch' mode. This endpoint either persists to disk, takes the editor loop, or executes outside theImporting writes new files to disk, which the current level, scratch, does not allow. The rest of the message tells a person how to allow it.
set_render_settings colorDepth=32, fileFormat=PNG
· Blender 5.2.1 LTS
REFUSED colorDepth '32' is not one the PNG format accepts: bpy_struct: item.attr = val: enum "32" not found in ('8', '16'). The enum's own item list reports 8, 10, 1...PNG images cannot be 32-bit. The reply names the bad value and the values that work, so the AI can fix its next try.
