Sketchup Mac 2025 how to purge just material only?

Hi
In Sketchup 2025 Mac - how to purge unused materials only. There is a purge function in Model info / statistics - but this purges everything include Tags which I want to keep. So how to be more selective.
I want to be able to purge used materials and components only. simple.

if you can help thanks.

Sketchup on Mac doesn’t have trays(yet) if you press B the materials window will appear, there you can go to the in model materials and purge unused. However the best option for me is to use a plugin like cleanup3 and set it up to purge just the materials and every other thing you want to purge or keep on your model.


(bottom choice)


(second to last choice)

components then materials. some materials could be linked to unused components, so components first.

you can also get this plugin

it lets you pick what to purge
