A described piece vs. the real piece
Saying “add a cream boucle armchair” gets you an armchair Hiera imagines. Sometimes that is exactly right, and sometimes the client has already fallen for one specific chair from one specific catalog. Add object is for the second case: you bring the real product photo, and the render gets that piece, not an interpretation of it.
Place a real product in four steps
- Put both images on the canvas
The render you are working on, and a photo of the piece. A clean product shot works best; a white or plain background is fine.
- Choose Add object
Select the render and pick “Add object” in the toolbar, then point it at the product photo.
- Position it
Move, scale and rotate the piece until it sits where it belongs in the room. You are composing the shot, so take the time to get the size believable.
- Generate
Hiera blends the piece into the scene: grounded, lit by the room’s light, casting its shadow. The rest of the render stays as it was.
Scale is what sells the illusion. Before generating, compare the piece against a doorway or the sofa; if it reads too large or too small there, it will read wrong in the result too.
Where this fits in a project
Sourcing is half of interior design: the moment a real product enters the conversation, the render should show that product. Clients approve faster when the room contains the actual chair they will pay for, and the render doubles as a staging preview before anything is ordered.
