Installation

What you need

• Autodesk 3ds Max 2026, 2025 or 2023
• Windows 10 or 11, 64-bit

Steps

1. Close 3ds Max. While it is running, the plugin file cannot be replaced.
2. Download the .dlo file for your 3ds Max version from the download page.
3. Copy it into the plugins folder, usually C:\Program Files\Autodesk\3ds Max 2026\plugins\ — with your version instead of 2026.
4. Start 3ds Max.

The object then appears under Create → Geometry → SplineGround.

Using your own plugin folder

If you keep third-party plugins in a separate folder, add that folder in Customize → Configure System Paths → 3rd Party Plug-Ins instead of copying the file into the 3ds Max folder. Then restart 3ds Max.

If the plugin does not appear

Check, in this order:

• the .dlo file is really in the plugins folder, or in the folder you added;
• 3ds Max was fully closed when you copied the file, not just minimized;
• the file was downloaded for your 3ds Max version — a file for another version will not load;
• the log file SplineGround-debug.log: if something went wrong at startup, it may have a hint. To open its folder, paste %LOCALAPPDATA%\SplineGround\logs into the File Explorer address bar and press Enter.

Uninstalling

Close 3ds Max and delete the .dlo file from the plugins folder.
