Hi I was wondering if there is a way to do this simple task instead of going one by one (more than 100 materials to delete)
Purge does not work because somehow some geometry or group has the material assigned.
I would be nice to select multiple materials at once from Materials Default Tray and delete them. Same as when you want to delete multiple files from Windows folder.
Use this excellent extension from ThomThom - Material Tools. You can delete materials by selection, which I do all the time as usually I want to remove materials from just single group or component. It does other things as well but this one tool is the most useful I’ve found.
Thanks, yes I have it, unfortunately it does not enable me to delete multiple specific materials, only one by one.
Selecting the geometry is no good for me because I don’t know which geometry actually has the material I want to delete.
Understood. I see. If you don’t know what has the material applied to it then you’re stuck with manually removing each material. No fun.
Give this small plugin (a tool I’ve written for @Cyentruk) a try to see if it meets your requirements!
@ShynnSup TT replace material (with eyedropper) plus Purge is the best solution for decades to get precisely what you want
I’m not sure how you want to delete them, the easiest way is from the materials tray, click on the house and delete the materials on your model that you dont want to use anymore, other option is if you want to apply a different material to an specific group or component is using selection toys from ThomThom, or the native selection tool on the contextual menu, you can select all the faces that have the same material then on the entity information tray click on the square where the material is shown and choose the default one or the one you want to replace with.
I think ShynnSup’s question is pretty simple and something that I think Sketchup should have solved a long time ago. The question is how can you delete multiple materials at once in the Materials Tab in the Default Tray. For example, everytime you start a new sketchup file there are materials already in there from the figure person embedded in the file. Sketchup doesn’t allow you to just go in to the Materials tab and deleted all those materials at once. Super annoying. You can only delete them one at a time. So, when you have a file with hundreds of materials that you no longer need or was brought in from another file, there is no way to delete those unwanted materials at one time.
You can purge them. If they aren’t used will be deleted
That looks like it works for what Shynsupp and I are wanting. However, it’s not a free plugin.
Thanks rtches! That’s a nice trick I didn’t know about. Though, it would be still good to be able to select multiple materials in the Materials Tab.
But if they’re used there’s NO WAY to delete them all at once. Without an extension (eye roll) you have to do it manually one at a time which is, frankly, a limitation for no good reason.
It can also be an advantage for some users.
