Redesigning a Room with a Single Prompt — A Real Workflow
A real workflow, end to end, from a designer who was tired of fighting SketchUp every time a client wanted to tweak the rug.
# The starting prompt
"Draft a 12×14 ft bedroom, mid-century modern, north-facing window, queen bed, two side tables with reading lamps, an oak floor and a low-pile rug under the bed."
Yugma's AI Director places the bed, the side tables, the lamps, the floor, the rug, the window, and a base lighting setup in one batch. Total: 11 objects, ~90 seconds.
# Iterating with the client live
The client opens the share link in a browser — orbit-only, comments enabled. They drop a comment on the rug: "can it be a vintage runner instead?"
In the chat panel:
"Replace the rug with a vintage Persian runner, 8×3 ft, under the bed and extending into the room."
Yugma fetches a credible Sketchfab match for the runner, swaps the rug, scales to 8×3 ft, places it. Client refreshes. They love it.
# Material variations
The client wants to see oak vs walnut. Two prompts:
"Switch the floor to walnut herringbone."
"Show me the same room with the floor as oak parquet for comparison."
Yugma keeps a version history; flipping between the two for the client takes one click.
# Lighting moods
Three prompts, three lighting moods, evening / morning / overcast:
"Set the lighting to soft evening — warm 2700K, low intensity, two accent lamps on."
"Switch to morning — bright daylight from the north window, lamps off."
"Now overcast — flat diffuse fill, no shadows, neutral 4500K."
Each is a single set_environment + a few apply_material_preset calls.
# Sharing & exporting
Designer hits Share → client gets a link with comments enabled. Designer hits Export → GLB downloads for the final Blender render, USDZ for the client's iPhone walkthrough.
# What this replaced
Before Yugma, the designer's workflow was 2 hours in SketchUp + 30 minutes in V-Ray for a single look. With Yugma, the same project is 10 minutes for a draft and another 5 minutes per variation.
