Style Toolbar Photorealstic materials icon

Hello, I have a problem with the style toolbar with the photorealistic materials icon on display which is grayed out and inaccessible and I don’t know how to activate it. I am using Sketchup Studio 2025 under Windows 11. Thank you for your help

Make sure you are using the new graphics engine. Check in Preferences>Graphics. If you’re using the classic graphics engine the PBR option won’t be available.

Geat Thanks a lot !
