How to get rid of Unused Textures from Materials List

Mistro11

Hello community. I usually like to test models I get from 3D warehouse as I compose my scenes. I realized that even after I delete the model I reject, the textures stay in the "in model" list. Does the amount of textures affect the performance of Sketchup? My current scene has gotten very slow on load and save times and I wonder if I get rid of the numerous textures that probably load with the scene I might get some load/save speed back. Even aside from the performance theory I just want to clean up the materials list so if I want to use a texture on multiple faces I won't have to sift through such a large list. I see I can just delete one by one but is there a way to isolate the ones not currently on any faces in the scene? I'm afraid of deleting a texture that might be in use as my scene is getting more populated and complex. Any suggestions is appreciated.

window -> model info -> statistics -> purge

It's not only the textures that get accumulated in your model but all the downloaded stuff as components (see your Component browser > In model folder, too). Though you can purge components and materials (in this order) individually in their respective dialogs, best is to do what Jeff suggested as that purges everything at once (also empty layers and unused styles).

I assign a shortcut to this plugin that purge the whole model: http://forums.sketchucation.com/viewtopic.php?t=11758

Big Thanks for your replies!
Jeff, it worked like a charm. My load/save time is back to reasonable amount and my material "in model" list is now clean.

@ThomThom...what's the advantage in using that ruby (purge all) compared to the window/model info method?

You can assign a shortcut key to it. Simply saying: faster.

My PurgeAll script also allows you to control what is purged - unlike the Model Info version which purges everything.
With my script if, for example you don't want to purge unused layers, you can choose not to...
You can also get a report written showing what has been purged...
