Diagnostic flow for “visual” issues such as strange screen display, wrong colors, or no shadows.

If experiencing heavy operation, stuttering, or app crashes

For performance issues, refer to Performance & Crashes page. Power check and GPU settings may help.

Dissatisfaction with Quality (Not Photorealistic)

Solutions when “room displays but quality is poor,” “looks like cartoon, not realistic,” or “looks CG-like.”

Real-time screen looks cartoony / flat / no shadows

[Diagnostic Flow]

  1. Is Quality Settings at “High” or above?

    • If set to “Low” or “Medium”, latest light calculation technology (Lumen) is disabled, shadows and reflections are omitted, resulting in “game-like/cartoon-like” appearance.
    • Solution: From settings at top right, change quality to “High” or “Epic”.

  2. Is graphics card (GPU) spec sufficient?

    • With “integrated graphics” like Intel Iris Xe, High settings may become very heavy or display incorrectly.

[Solution]

  • Use high-spec PC or utilize “still image export (Path Tracing)” described below.
Want more photo-like quality (photorealism)

[Solution: Using Path Tracing]

To generate “photo-like” images in R.Design, Path Tracing mode rendering is essential. Real-time screen (walking around screen) is merely “preview,” not final quality.

  1. Press Render button (camera icon).
  2. In settings screen, change Render Mode to “Path Tracing”.
    • ※Much higher quality than default “Lumen.”
  3. Perform export.

Materials look cheap

[Checkpoints]

  1. Roughness Settings
    • Is everything too shiny? Increasing roughness of cloth or wood to make it “matte” looks more realistic.
  2. Normal Map
    • Is there surface unevenness? Applying normal maps adds dimensionality to wallpaper and floors.

Overall Screen Brightness & Display Issues

Room is pitch black / Doesn’t brighten even with added lights

[Diagnostic Flow & Priority Checks]

Cause is usually “camera” or “settings” rather than “lighting.” Check in this order:

  1. Is camera “inside wall”?

    • Try moving with keyboard (WASD) to see if scenery changes. Being embedded in wall makes it pitch black.

  2. Is it imported model?

    • Window glass material may not be letting light through.
    • Solution: Move active camera outside house to check, or apply R.Design’s “Clear Glass” material to windows.

  3. Is environment setting (HDRI) loaded?

    • Rarely, sky brightness info (HDRI) fails to load due to bug.
    • Solution: Try changing preset.

  4. Is camera exposure setting on “Manual”? (★Important)

    • If camera setting’s Exposure Metering Method is Manual, camera won’t increase sensitivity even when surroundings darken.
    • Solution: Return setting to “Auto”.
    • Reference: Camera Exposure Setting Troubles

Rendering (Export) Results

Mirror reflections are blurry

[Diagnostic Flow]

  1. Is quality setting “High”?
    • At “High,” reflection calculations are simplified for lightweighting.

[Solution]

  • For sharp reflections, set to “Epic” (requires high-spec PC).
  • For still image export, using “Path Tracing” regardless of settings will resolve it.
  • Reference: CG Terminology: Ray Tracing
Crashes during video or panorama export

[Diagnostic Flow]

  1. Do you have 12GB+ VRAM?
    • Path tracing output for videos or 360° panoramas consumes far more VRAM than normal operation.
