Render Fun’s piggy bank
The people who back Render Fun so it stays free. Every contribution lights a lamp in this piggy bank.
“I don’t need a new licence budget to start rendering.”
For architects and interior designers who care about the image
Turn your SketchUp model into a photo-real view.
Light, shadow and materials take on their real look in your model’s own window; what you show the client is no longer a drawing but the space itself.
For those who care how the engine works
GPU path tracing. Inside SketchUp. Free.
An engine that traces light on the graphics card: no export, no account, no licence key. Free for personal and commercial work.

Render Fun
What is Render Fun?
A render engine that lives inside SketchUp. It reads your model as it is, traces real light on the graphics card and shows a usable picture from the first second, so you judge light and materials while you design rather than after an export. It was built so that a ten-year-old could take a render without reading anything, and a visualiser still finds colour management, light mixing and IES lamps one click deeper.
How does it work?
Your model goes straight in
Render Fun opens as a window inside SketchUp and reads the model itself: triangles, materials and textures, camera, sun and lamps. There is no separate program, no export file and no import step. Move the camera or change a material and the render window follows.
The graphics card traces real light
For every pixel the graphics card follows rays of light as they bounce off walls, pass through glass and fall into shadow. This is path tracing, the same principle the big offline renderers use, running in SketchUp's own window through WebGL2.
The first image comes at once, then it sharpens
You do not wait for a finished frame. The first pass appears immediately and every pass adds light samples, so the picture cleans up while you watch. Stop whenever it looks good enough, or let “Until clean” stop by itself once the image is clean.
A denoiser cleans up the rest
While you work, a fast denoiser keeps the preview clean even at a few samples. For the final render on Windows, an AI denoiser runs once at the end.
From the first second to the final frame
From noise to a clean image
The same 16 samples: drag to compare the raw image with the denoised one.
⇆
Change the hour, the light follows
The same room as the sun goes down from 40° to just below the horizon. Every frame is a real render.
Features
What makes it different
01
Fast real time
Press the Real-time button and walk through the model like in a game: W A S D, drag to look, Shift to run. Sun shadows, bounced light, reflections and glass are drawn instantly, and RENDER gives the path traced image from the angle you stop at.
02
Plants
Our own plant pack of 129 trees, shrubs, grasses and indoor plants: scatter them over a terrain, line them up along a path, place pot plants with a click, turn surfaces into lawns and keep paths and terraces clear, while the SketchUp model stays light.
03
Render inside SketchUp
No second program and no export. The camera follows at once; sun, materials, geometry and tags update live as you model.
04
Simple enough to use without reading
Pick the weather, pick the quality, press RENDER. Every panel opens with one-click presets; the sliders are under “Detailed settings” for whoever wants them.
05
One-click scene presets
Interior day or night, exterior day or sunset: one press sets the light, colour and detail, then suggestions for your scene follow, each with its own button. Finish the look with film filters.
06
Smart Check
One button scans your model and lists what slows a render down or spoils it: leftover lights and proxies from other render engines, empty groups, duplicates, oversized textures, reversed faces and more. Tick what to fix and it is done in one step; one undo brings everything back.
07
Before / After, ready to share
After a render, turn the SketchUp view and the finished image into a slider page or a 5-second video with the renderfun.com mark: ready for your client, your portfolio or social media.
08
AI denoiser and “Until clean”
An AI denoiser on the final render (Windows), and “Until clean”, which stops the render by itself once the image is clean.
09
Sun, sky and HDRI
Physical sky with SketchUp's own sun, 10 built-in CC0 HDRIs, your own .hdr / .exr files and SketchUp 2025+ environments, with rotation, strength and background options.
10
Lamps like a lighting designer
Point, spot and panel lamps, IES light distributions, glowing textures, and a light mixer that changes lamp groups' power and colour after the render.
11
Materials in one click
Click a surface and choose matte, glossy, metal, glass, mirror, water, fabric or car paint; SketchUp 2025 PBR maps are read; a name like “glass” or “emissive 200” sets the type; a material library of 20 categories with 298 texture sets comes built in. Smart UV places a texture at its real size in one click.
12
Your own library
Textures, colour presets and models in one window: add your own textures and .skp models, link your archive folder without copying, sort them into nested folders and place them with one click.
13
Colour and detail without re-rendering
AgX, ACES and Filmic colour management, colour correction, white-point picker and looks; ambient occlusion and cavity edges. They work on a finished image, instantly.
14
Quality where it counts
Four anti-aliasing levels, faster interiors, depth of field and bloom.
15
Built for large models
Large models open about twice as fast as before.
16
Render Buffer
Every finished render lands in one window, newest first, numbered RenderFun001, RenderFun002… so nothing is overwritten; the last 60 are remembered after SketchUp closes.
17
Turkish and English
Every word of the interface in both languages, with a picture guide built into the plugin.
Workload test
No monthly AI render subscription: do the same job on your own computer, free.
A year of renders, what it costs
- No credits, no quota: render as much as you like
- No internet needed; HDRIs, textures and the denoiser are in the plugin
- Your model and images never leave your computer
Subscription prices are the annual plans two widely used AI render services listed on their own pricing pages on 11 October 2026 (Veras Pro €330; mnml.ai Plus $490, Studio $1,190). Taxes may be extra and prices can change. Render Fun is free; all it needs is a graphics card with WebGL2.
The interface
One screen, a rail of panels on the right: presets first, sliders one click deeper.
Benchmark

- Windows. macOS has not been tested yet.
- Graphics card
- A graphics card with WebGL2 support; Render Fun sets its quality to the card by itself, and a compatibility mode helps cards that cannot run the full renderer. Measured so far on an NVIDIA RTX 4090; integrated graphics have not been measured yet.

Questions
Is Render Fun really free?
Yes. Render Fun is our own render engine and it is free to download and use, for personal and commercial work, with no account and no licence key. Download the .rbz on this page and follow the install steps below it.
How do I install Render Fun in SketchUp?
Close SketchUp, open renderfun-0.75.1.rbz with WinRAR or WinZip and extract all the files inside it into C:\Users\<your user name>\AppData\Roaming\SketchUp\SketchUp <your version>\SketchUp\Plugins. Then start SketchUp: Render Fun is in the Extensions menu and on its own toolbar.
Do I need a powerful graphics card?
Render Fun runs on any graphics card with WebGL2 and picks its quality from a short speed test when it opens. A faster card simply cleans the image sooner. So far it has been measured on an NVIDIA RTX 4090; integrated graphics have not been measured yet, and we will publish those numbers when we have them.
Does it need an internet connection?
No. The HDRIs, the texture library and the AI denoiser are inside the plugin; nothing is uploaded.
Does it change my SketchUp model?
Only what you ask it to. Render settings are saved with the model; a material type you pick and the Render Fun lamps you place are written into it, and a material choice or a lamp-size change is one step to undo.
Does it work on a Mac?
It has not been tested on macOS yet, so we do not claim it. Today Render Fun is built and tested on Windows.

Our SketchUp plugins build the floors, doors, windows, stairs and furniture; the free texture library dresses them.
