Links: blog post | download Seeing the blue accent theme topic reminded me that I wanted to do a small theme for a while, so I did, and wrote up instructions on how to make themes that won't easily break between GMS2 updates. Installing: Spoiler Navigate to %PROGRAMDATA%/GameMakerStudio2 Note: not Program Files! Skins folder in PF will get overwritten whenever IDE updates. On Mac, it's likely in Application Data - check where runtime_feeds.json is via Finder. Open the Skins directory, or make one if it's not there yet. Extract your skin into a subdirectory in Skins so that you have Skins/<skin name>/Styles, etc. Choose the skin in GMS2 via menu:File - Preferences - General - IDE Skin.
