Editing materials and lighting like a pro

May 21, 2026 · 5 min read

Materials and lighting

The first render gets you 80% there. The last 20% — the part that makes a scene look intentional instead of automatic — is all materials and light. Here's how to dial it in.

Edit by prompt first

The fastest way to change a scene is to describe the change. AIHom keeps the scene fully editable, so you can say what you want and re-render:

  • "Make the floor wide oak planks instead of tile."
  • "Repaint the accent wall a soft clay."
  • "Warmer evening lighting, lamps on."

Change one thing at a time. It's tempting to rewrite everything in one prompt, but small, single-purpose edits give you cleaner control and make it obvious which change did what.

Then go hands-on for the details

When you want precise control, open the advanced editor. There you can select a specific surface, swap its material, adjust a single light, or nudge a piece of furniture — without disturbing the rest of the scene. Prompt for the broad strokes, edit by hand for the finish.

Getting light right

Pick a direction

Flat, even light is the most common reason a render looks generic. Decide where your main light comes from — a window, a fixture — and let the shadows fall from it. Direction reads as realism.

Match the mood to the time of day

Bright, cool daylight suits a clean listing shot. Warmer, lower light with lamps on suits a cozy living room. Tell AIHom the time of day and it sets the temperature and intensity to match.

If a render looks "off" but you can't say why, it's almost always the lighting — not the furniture.

Getting materials right

  • Watch the scale. Oversized grain or tile is the quickest way to break realism. If a surface looks wrong, check its scale before anything else.
  • Limit the palette. Two or three materials doing most of the work looks more designed than ten competing ones.
  • Use real products. Pulling from the branded catalog keeps finishes consistent and, helpfully, buyable.

A simple workflowLock the layout → set the lighting direction and mood → fix materials by surface → render a hero angle → only then fine-tune the small stuff. Doing it in that order saves the most re-renders.

Iterate without fear

Because every change re-renders in minutes, you can try a bolder palette or a different time of day just to see. The scene stays editable the whole way, so nothing you try is permanent — and that freedom is exactly what makes the result look considered.
