SketchUp lighting and daylight visualization plugin with real-time scene feedback

  • Turn LightUp SketchUp views into polished AI renders.
  • Zero Footprint: We don't install inside LightUp. We overlay it.
  • External Compute: Your GPU draws lines. Ours calculates light.
  • Batch Processing: Serial rendering is for amateurs. Do it all at once.

When to use RENDERCAD with LightUp

LightUp users often work from a SketchUp model that already communicates lighting intent: daylight studies, Sky Factor or VSC views, interior fixture tests, material reflections, and walkthrough angles. RENDERCAD fits after that setup work, when you need a polished client still without rebuilding the scene in another renderer. Capture the LightUp viewport from a clean architectural, retail, exhibit, product, or interior view and generate a presentation-ready render with clearer materials, softer lighting, and stronger atmosphere for design reviews, proposals, and marketing previews.

Capture.
Render.
Done.

In SketchUp, finish the LightUp view you want to present: set the sun or sky study, confirm key light sources, hide construction guides, and frame the room, facade, product, or walkthrough moment. Capture the viewport once the lighting reads clearly, then upload the image to RENDERCAD. Use the result as a fast presentation render for client review, option comparison, concept marketing, or a more polished companion to LightUp stills and fly-through previews.

Questions & Answers

Common solutions for LightUp users

Use RENDERCAD's "Realistic" engine and "Exact" style. This combination delivers the highest fidelity.

You eliminate the setup time. Instead of positioning lights and tweaking materials, you upload or snip an image, prompt, and wait roughly 20 seconds for the result.

You don't need to assign materials to parts. You just tell RENDERCAD "The body is red plastic, the handle is rubber," and it visually paints the materials for you.

The "Creative" style allows for hallucination of details that don't exist in the CAD, helping you visualize "what could be" before you model it.

There are no dongles, no license servers, and no installation wizards. You just log in and start rendering.

It creates emotional storytelling (e.g., a "well-loved" tool vs. a "new" one) by simply selecting from Clean, Slight Wear, Heavily Used, or Dirty in Advanced Settings.

No, image references and masks require Realistic mode. Fast mode is optimized for speed and doesn't support reference inputs. Switch to Realistic for full control.

Masking lets you select specific regions of your CAD screenshot, real photo, or hand drawing and apply different reference images or prompts to each area independently.

Yes. Generate a concept image first, then use it as a style reference for your LightUp model to achieve that specific aesthetic.

Prompt for "Cut ruby," "Emerald," or "Sapphire" with "Light refraction" to capture the internal sparkle.

Upload your image or snip your screen, then type "Cyberpunk city, neon lights" in the prompt. The "Creative" style will restyle the atmosphere while keeping your model's core shape.

Yes. Select the "Slow zoom in" or "Slow zoom out" camera option in RENDERCAD Image-to-Video to create dynamic motion from a still image.
