The recently-released 3.3 version of my SketchUp AI Explorer (Experimental) extension now allows for an interesting and potentially (depending on your hardware) useful way to work with AI in SketchUp: You can now use local LLMs on your computer via a software like LM Studio as the AI provider for this extension.
This approach is 100% free and only depends on the hardware capabilities of your local computer. This means you don't have to pay for tokens and you can even choose among a fairly large number of AI LLM models (including GPT-OSS, QWEN, GEMMA, DEEPSEEK,…). And nobody will ever train their AI systems on your prompts. One word of caution, though: This is largely an experimental approach and its effectiveness is very much dependent on your hardware (especially your GPU). But if you tweak this setup to your liking, it may open up new avenues.
How Does This Work?
To be able to do this, you will need two things:
The Ai Explorer (Experimental) extension,...
Now that version 2026.1 of SketchUp is rolling out, we are getting a clearer picture of where SketchUp's AI implementation is heading. As you likely know, the SketchUp folks had previously released SketchUp Diffusion, a rendering and visualization solution. At the last Basecamp, they then also teased their AI Assistant, which was implemented as a chatbot that could show help topics, write Ruby code, and do various other things that are implemented within an extensible dialog.
As of the latest version, there is now a single toolbar button (yes, it's YAMDB = yet another magic dust button) that brings up the SketchUp AI interface, which now looks like this:
There are two tools listed in there: AI Assistant and AI Render (the new iteration of SketchUp Diffusion). In addition, they introduced a credit system for the various AI tools where users get some credits as part of their subscription plans, but can also buy additional ones, as needed. This floating toolbar now...
Now that SketchUp 2025 has been released, SketchUp's materials have experienced a significant upgrade. All materials that ship with SketchUp are now PBR (physically-based rendering) materials that look much better than the older materials, which at the time were designed with efficiency in mind. However, that efficiency often came with graininess, unpleasant repeating patterns, and some other artifacts. The new materials are in many cases of render-quality while still being quite efficient.
As a result of this change, the size of the entirety of all shipped materials went from 8.9 MB (SketchUp 2024) to 248 MB (SketchUp 2025).
How About SketchUp's Old Materials?
So, what do you do if - for consistency reasons or any other - you want to keep some of the old pre-2025 materials around (in addition to the new ones)? It is actually easy to do that. As long as you haven't uninstalled SketchUp 2024, they are all still on your hard-drive!
Here are the steps:
Step 1: Find...
This image of a wood-veneer tray with a decorative brushed metal ball was exported right from SketchUp - no rendering software needed
SketchUp 2025 introduced a new graphics system for materials: PBR (physically-based rendering) photoreal materials. As you can see in the image above, you can now have shiny, glossy, dimpled, and otherwise textured materials right in SketchUp's model area. You can then use that new appearance while modeling or when you export images or animations.
As I discussed in my review of SketchUp 2025, the PBR materials look best when you enable one of the new environments (you can see one in the images below (in the reflection). In addition, you may need to make sure that the "Photoreal Materials" are also enabled for SketchUp's modeling area. You can do that on the Styles toolbar or in the View > Face Style menu.
In this post I will give you a visual overview of the new PBR material parameters. So that the...
Interior reflections like these (on the floor) can easily be done right inside SketchUp with this little trick
SketchUp 2025 introduced some very nice visualization capabilities: PBR (physically-based rendering) materials and environments. While those are great (especially for exteriors), indoor material reflections are a bit trickier since objects cannot be reflected even with the new PBR materials.
In this tutorial I'll show you how you can create some good-looking reflections (in e.g. floors or mirrors) with a simple trick. Check out the video below for a walk-through of the process. But in short, here's what you need to do:
Step 1: Create an inverted copy of the model
As a first step, turn your entire model (or at least what will be visible) into a group - or even better: a component (to retain the live link between the two copies). Then flip it along the reflective surface either using the Flip tool or by copying/scaling it. In my case I need a floor...
