FLUX 3 Image: Common Questions Answered
Straight answers on how boxes, canvas grids and scene lines shape the FLUX 3 Image you get.
How do the boxes control placement?
Every rectangle you draw marks the area reserved for one object, so the element you described for that region appears inside it.
Why is the canvas measured on a 0–1000 scale?
No matter how wide or tall the frame is, both axes run from 0 to 1000, which keeps every box coordinate on one consistent scale.
Should I pick the aspect ratio first?
Yes — choose the frame shape up front, and because both axes stay on a 0 to 1000 grid, your coordinates remain readable whichever shape you pick.
What role does the scene prompt play?
It is the single line that connects the separate regions into one picture — the route used for the 'Le Festival du Soleil' example built from boxes plus a scene prompt.
Can I give every box its own description?
Absolutely — after drawing a rectangle you add its own content note, so each region carries an independent instruction.
Are subscriptions or seat fees involved?
Not at all — you pay only for what you generate, with no subscription plans and no per-seat charges, and open-weights licensing tiers exist for running the models on your own infrastructure.
