Installation

Installation

1. BepInEx & API

1. Install BepInEx 5 for your game if not already present.
2. Ensure HS2API / KKSAPI / KKAPI is in the BepInEx/plugins/ folder.
3. Launch the game once so BepInEx creates its folder structure.

2. Download modules

Latest builds are on the GitHub Releases page. Versions and direct URLs are also in versions.json.

Recommended: Individual modules (split)

Copy only the DLLs you need, for example:

BepInEx/plugins/HS2-Sandbox/
  HS2Sandbox.PoseBrowser.dll
  HS2Sandbox.AnimBrowser.dll

Subfolders are fine — BepInEx loads recursively. Toolbar icons ship inside each DLL — nothing extra to copy.

Alternative: All-in-one (HS2, legacy)

HS2SandboxPlugin.dll bundles CopyScript, Timeline, Son Scale, Notebook, Pose Browser, SearchBarManager, and Workspace Tree Lock in one DLL.

→ See All-in-one vs split modules — do not load it together with split DLLs for the same features.

3. Game-specific DLL names

Game	Pose Browser	Anim Browser
HS2	HS2Sandbox.PoseBrowser.dll	HS2Sandbox.AnimBrowser.dll
KKS	KKSSandbox.PoseBrowser.dll	KKSSandbox.AnimBrowser.dll
KK	KKSandbox.PoseBrowser.dll	KKSandbox.AnimBrowser.dll

Never use the HS2 DLL in KKS/KK (or vice versa).

4. First launch

1. Start Studio (StudioNEOV2.exe or CharaStudio.exe).
2. Use the left toolbar — click icons for installed modules.
3. If something fails, check BepInEx/LogOutput.log.

Modules without a sidebar button

Module	Behavior
SearchBarManager	Search bars appear automatically on configured Studio panels
Workspace Tree Lock	Middle-click in the workspace tree — no separate window

5. Configuration (optional)

• BepInEx Configuration Manager — UI scale, hotkeys, auto-capture delay, etc.
• Config files under BepInEx/config/com.hs2.sandbox/ — see Configuration & data files
