Before you start
Prepare your render or model view
Material decisions are easier when options sit side by side in the same image. Start from a render or model view, then ask RenderChat for one change at a time — cabinet color, worktop stone, facade cladding — while the rest of the scene stays put.
Change one thing per message
One material per request makes it clear what changed and keeps the rest stable.
Use real samples
Attach a photo of the actual material sample when color accuracy matters.
