This tutorial will guide you through the steps of locating, downloading, and then uploading these brushes.
In Photoshop go to brushes - get brushes this goes to Adobe where they have all of Kyle Webster's brushes.
Uploading to Photoshop
Once in Photoshop, you'll want to open your brush tool panel in the top left corner of your workspace. Once that menu is open, click on the little gear icon in the menu's top right corner. A dropdown menu will appear with a list of commands, one of which should be labelled "Load Tool Presets".
Clicking on this option will open a Finder window that you will then use to navigate to where ever Kyle Webster's Ultimate Megapack was saved. When you locate the folder, open it and select the file named "Megapack_Full_Set.tpl". Photoshop might need a few minutes to think about what its doing, but eventually the new brushes will load into the brush tool menu. Once that set has been loaded in, you'll repeat the process to upload the file named "Tilterrific_2015_CS6andUp.tpl" from the downloaded folder as well.
With those steps completed you'll now be able to access your new brush sets in the tool panel in the top left corner of your screen!
