I dont need the fancy terms and explanations no one is reading.

Im just simply saying, when i add sprays, and i try to import them normally it will not work right. Either the background will be all white, or the quality will look like shit.

So i create a vtf and vmt file from my sprays and put them in materials > vgui > logos. Then import the vtf by going there with the browser.

This has also worked for everyone else i helped that couldnt get their sprays working.
