Improved Stacker Tool
The Improved Stacker tool is a complete rewrite of the original Stacker tool and includes many bug fixes and new features that both clients and server owners can benefit from.
Unlike the other versions of the tool, the Improved Stacker tool is also currently being actively maintained.

Please DO NOT reupload this tool (verbatim or small tweaks) to the workshop or other public file-sharing websites. I actively maintain this tool, so reuploading it may lead to people using outdated, buggy, or malicious copies. If there is an issue with the tool, LET ME KNOW via one of the following pages:

• GitHub:
• Workshop:
• Facepunch:

OverloadUT (STEAM_0:1:5250809) :: Wrote the original Stacker Tool in 2006
Marii (STEAM_0:1:16015332) :: Updating OverloadUT's Stacker Tool for GMod 13, also being the starting platform for Improved Stacker

Multi-language Support:
The Improved Stacker tool features multi-language support (listed below). If you are multi/bilingual, please consider helping by providing translations into other languages. You can find the list of phrases to translate at

- Supports Bulgarian ([BA][Sk$Bh]Trick or treat KID!): Натрупвач - Подобрен
- Supports French (TheRoyalDark/Felix): Stacker - Amélioré
- Supports Polish (Sarian): Stacker - Ulepszony
- Supports Russian (SupinePandora43): Стакер - Улучшенный

• Prevented a crash from players using very high X/Y/Z offset values.
• Prevented a crash from players using very high P/Y/R rotate values.
• Prevented a crash from very specific constraint settings.
• Fixed applying halos to ghosted props and the FPS drop they were causing.
• Fixed material and color saving when duping stacked props.
• Fixed incorrect stack angles when trying to create a stack on an existing stack.
• Fixed incorrect stack angles when stacking in a direction other than 'Front'.

• Added support for applying materials to props.
• Added support for applying colors to props.
• Added support for applying skins to props with multiple skins.
• Added support for applying physical properties (gravity, physics material) to props.
• Added support for applying weight to the stacked props (toggleable, under Physical Properties).
• Added toggleable axis and axis labels[] showing a prop's orientation.
• Added presets[] to save your settings so you can reuse them.
• Added language support (like with my Improved Weight tool).
• Switched over to new tool HUD[] style
• Added more control via key combinations:
• - Right-click creates a single prop in the stack.
• - E (or SHIFT) + Left-click increases the stack size.
• - E (or SHIFT) + Right-click decreases the stack size, and Reload (R) changes the stack direction.

Try stacker_improved_set_delay 0 in your console to remove the delay. I didn't intend for there to be a delay in singleplayer, so that may have been something I overlooked.

How to disable the time cooldown in singleplayer? I fricking HATE that tine cooldown.

@Ltucker985, yes, they can still see your props once you've stacked them whether they have stacker or not.
