How to Render Photorealistic SketchUp Models with the VizBase Plugin

The Vizbase SketchUp plugin lives inside the SketchUp viewport. You position a camera in your model, click one icon, and a photorealistic render comes back in about sixty seconds — no exporting, no scene setup, no GPU workstation. This walkthrough covers the install, the first-render workflow, and the workflow tweaks that make the difference between a generic AI render and a render you can actually send to a client.

If you're still deciding between Vizbase and other AI rendering tools for SketchUp, read our honest comparison of seven SketchUp AI rendering toolsfirst. This post assumes you've already chosen Vizbase and want to know how the plugin actually works.

Why a SketchUp plugin matters

Almost every other AI rendering tool on the market — mnml.ai, MyArchitectAI, ArchiVinci, Visoid — works the same way: you export a screenshot from SketchUp, switch to a browser, upload, wait, download. It works. But it's four extra steps every time you want a render, and those steps add up over a day of client iteration.

The plugin removes the export, the upload, and the context-switch. You stay in SketchUp the whole time. Your camera stays put. Your model stays loaded. The plugin captures the current view directly, sends it to the Vizbase cloud, and the photorealistic render appears next to the original — all inside the SketchUp window. For junior staff, that's one tool to learn instead of two.

There's also a small geometry-fidelity advantage. The plugin has access to more model information than a flat 2D screenshot, which can improve edge accuracy on the resulting render — especially on Precision-mode renders where the structure is supposed to stay locked while only materials change.

Installing the plugin in four steps

The plugin ships as a single .rbz file and installs through SketchUp's Extension Manager. The whole process takes under two minutes.

1. Download the .rbz filefrom your Vizbase dashboard. The plugin is available from the Pro tier and above — sign up for the free tier first if you want to evaluate Vizbase's output before committing.
2. Open SketchUp (2021 through 2026 are supported on macOS and Windows). Go to Window → Extension Manager → Install Extension.
3. Select the .rbz file and approve the install when SketchUp prompts. The Vizbase panel will appear under the Extensions menu and as a toolbar button.
4. Sign in with your Vizbase account. The plugin connects to your credit balance and history, so renders made through the plugin appear in the same dashboard as browser renders.

There are no admin permissions required and no separate authentication beyond your Vizbase account. If your studio uses managed SketchUp installs, the plugin installs per-user — no IT ticket needed.

The 60-second workflow

The clearest way to see the plugin in action is to watch a 60-second render happen end-to-end. Capture, generate, download — all inside SketchUp 2026.

Capture → generate → download

Open any SketchUp model and position the camera the way you'd frame it for a client presentation. Click the Vizbase toolbar icon. The plugin panel opens and captures the current view — the captured Original appears on the left of the comparison area, and the Generated render appears on the right once it's ready.

The Vizbase plugin panel inside SketchUp 2026 — Original capture on the left of the panel, Generated render on the right, with credit balance, history, and the Inpaint / Upscale / Regenerate / Download controls.

Describe the materials you want in natural language — “warm oak floors, sage green painted walls, brushed nickel hardware, marble kitchen island” — or accept the auto-detected element list and tweak it. The render starts immediately and finishes in roughly sixty seconds. The Generated panel updates in place and you can Download, Inpaint, Upscale, or Generate Again from the same controls.

Each completed render lands in the History row at the bottom of the panel, so you can scroll back through previous attempts without re-running. The history is shared with your Vizbase dashboard, so anything you generate through the plugin is accessible from the web app too.

Inpaint, upscale, regenerate

Once a render lands, three follow-up actions matter most for real client work.

Inpaintlets you mask a region of the generated image — say, just the cabinets — and regenerate it with a new prompt while the rest of the image stays untouched. This is the iteration loop that wins client meetings: “show me the kitchen with white cabinets instead of walnut” takes one click and 60 seconds, not a whole new render cycle.

Upscaletakes the current render and increases its resolution for print and high-DPI client decks. The upscaled output retains the same image — it doesn't reinterpret materials — just adds resolution.

Generate Again re-rolls the entire image with the same prompt for a different interpretation. Useful when the first render is 80% there but you want to see two or three other versions before locking in.

Exterior renders use the same workflow

The plugin handles exteriors with the same capture → generate → download loop. The auto-detected element list adapts to the scene — for exteriors, that's typically facade, glazing, roofing, planting, paving, and sky.

The same plugin, running on a high-rise urban exterior model. The plugin panel sits on top of the SketchUp viewport while the captured view and generated render update in place.

Exterior renders skip the LAB structure lock that interior Precision mode uses — exteriors tend to render cleaner with a more direct Gemini-only path that emphasises lighting, materials, and atmosphere over hard geometric edges. The plugin handles this automatically based on the captured scene type.

Three generation modes — when to use which

The plugin exposes three generation modes, each tuned to a different stage of design work.

Standard (Gen 2.0). The default. Fast, ~30 seconds per render, costs one credit. Use for daily iteration during the design phase when you want to see options quickly.

Creative (Gen 2.1).Powered by Gemini 3 Pro Image. Slower, ~60 seconds, costs one credit. Use for stylistic exploration when you want richer material interpretation and a slightly more “photographic” look. This is the mode that wins client presentations.

Precision (Gen 2.2). Geometry-locked. ~90 seconds, costs three credits. Use when the source geometry has to stay pixel-accurate — planning submissions, late-stage client sign-offs, construction documents. The LAB structure lock means window mullions and beam positions stay exactly where you drew them while materials and lighting are reinterpreted.

Most projects use Standard for early iteration, switch to Creative for the final presentation render, and reach for Precision only when a specific image needs to match the source geometry exactly.

Tips for better SketchUp-to-render output

A few small habits separate a generic AI render from one a client signs off on.

Frame the camera like a photographer would.Don't capture from inside-the-wall or from a 100m drone height. Set the camera at standing eye-level (1.6m), at a comfortable focal length (35mm equivalent), and frame the shot the way a real estate photographer would. The plugin's output quality scales directly with how well-composed the source view is.

Be specific about materials.“Modern kitchen” gives you any modern kitchen. “Walnut cabinets with white marble countertop, brushed brass hardware, and a herringbone oak floor” gives you the kitchen in your head. The auto-detected element list is a starting point — overwrite it with the actual finishes you're proposing.

Use Inpaint instead of regenerating. If a render is 90% there and you want to change one element, inpaint just that region. Regenerating the whole image risks losing the parts you liked.

Save your favourite prompts.If you find a material description that consistently delivers good renders for a particular style, keep it in a text file. The Vizbase plugin doesn't yet have native prompt presets, but a clipboard of go-to prompts saves typing.

When the plugin wins versus the browser app

The plugin is the right tool when you're working in SketchUp daily and iterating on the same model across multiple sessions. The capture-from-viewport workflow saves real time once you're doing more than a few renders per day.

The browser app at vizbase.aiis the right tool when you want to upload a one-off screenshot, or when you're collaborating with someone who doesn't have SketchUp installed (the free tier and Starter both work in any browser without the plugin). They're the same engine, the same credits, the same dashboard — just different entry points.

Studios with multiple modeling tools — Revit, Rhino, Archicad — often use the browser app for non-SketchUp work and the plugin specifically when working in SketchUp. There's no licensing penalty for using both.

Plugin tier and pricing

The SketchUp plugin is available from the Vizbase Pro tier and above. Pro is $59/month (or $50/month on annual billing) and includes 75 credits per month plus the plugin. Studio at $109/month includes 175 credits — the right choice for studios running daily renders across multiple projects.

The free tier (5 credits/month) and Starter ($29/month, 30 credits) are browser-only. They're the cheapest way to evaluate Vizbase's output quality before stepping up to Pro for the plugin. Annual billing on any tier saves around 15%.
