S7NSK8 — Custom Cosmetics Pack

16 custom cosmetics for skate., including jerseys, shirts, a hoodie, a hat and skateboard graphics.

Installation

Install using ReSkate Mod Manager. This release includes the built ReSkate Studio patch files (layout.toc, initfs_win32, and Win32/) for the game to load, rather than only source .fbmod files.

Enable Loads when Skate starts in Mod Manager and launch the game. If you already deployed the same cosmetics with ReSkate Studio, disable or remove the duplicate deployment before testing the Thunderstore version to avoid conflicting copies. Back up your existing mods before making changes.

The original .fbmod files are included in SourceFBMOD/ for manual use with ReSkate Studio if needed. These files are not directly loaded by ReSkate Mod Manager.

Install S7NSK8

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for S7NSK8 and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.

skatemods doesn't host or review this mod. The download comes straight from Thunderstore. Only install mods you trust, because scripts can run code.
