Thanks so much for sharing this fix—really helpful. I actually found an even easier way: just delete the 2025 materials folder and drop in the 2024 one. Quick, clean, and it works.
But honestly? I was stunned by this change. You open the new version, and boom—most of the materials are gone, and what’s left are these sharp, aggressive thumbnails pointing right at you. It’s like someone broke into your workshop, stole your tools, and left a note that says, “Good luck!”
It didn’t feel like an upgrade—it felt like a warning shot. But hey, big thanks to the community for fixing what Trimble messed up.
Let’s fix SketchUp and make it usable again.
