Blender 2.8+

The official version on the website is always supported first and foremost but the developments also cover buildbot.

Boxcutter Installation

Updating Blender requires the latest updates. https://builder.blender.org/download

If updating Blender one must also update the Hard Ops / Boxcutter packages for the latest version.

  1. Firstly ensure Blender 2.8 is up to date.

  2. Buildbot Blender

  3. Blender Updater Windows

  4. Ensure the latest zips are downloaded from the markets.

Boxcutter / HOPScutter Bundle

  1. Copy the contents of the zip to the addons location. C:\Users\YOUR USER\AppData\Roaming\Blender Foundation\Blender\2.8X\scripts\addons Remove any old HOPS / BC folders. Never overwrite.


3a. Or use install from file. But this only works if the folder is not there already! Otherwise... issues. In the addon panel locate Boxcutter and delete them then you are able to install the newer update. Make sure the folders are not there and it should work fine.

(DO NOT try to install it on the blender install itself. That has shown to not work. ex: C:\Users\RUSER\Desktop\Blender Builds\2.8-updater\Git-f18373a9ab1a-25-May-23-18\2.80\scripts\addons - this is not the right place. See 3.

  1. Open Blender and enable the add-on. I delete my config so blender would open cleanly without issue from previous prefs.

4a. If using install from file. As shown in the video. It will isolate the addon for enabling. After enabling do not double click while waiting. Just give it a second if you know you clicked it. Registrations can take a moment sometime.

And then Blender is able to be loaded and the addons enabled. Errors indicate that the HOPS/BC installation is possibly old and requires redownload. Also make sure it is installed in the correct path.

Detailed Install Instructions

Windows 10 / 7

When using Blender a folder is created deeply in your PC for add-ons. Putting it
here instead of the branch you are using ensures the next updates also have it

C:/Users/ USERNAME /AppData/Roaming/Blender Foundation/Blender/ 2.XX /scripts/addons


Locate Blender in your applications folder

install from file in Blender works best.


I assume linux users know their PC.

~/.config/blender/ 2.XX /scripts/addons


Q: I can't install Boxcutter!

Make sure you copied the contents of the zip into the directory mentioned above. Also try reopening blender.

Q: Boxcutter won't enable!

Try reopening Blender! Also check installation. Boxcutter latest version only works with Blender 2.8 and above. The api changes before will cause issues with old blender.

More about installation.

When it comes to diagnosing issues with install a screenshot of the issue would help with diagnosing errors.

The easiest way to restore blender to defaults is to delete the config folder for your blender installation.

The local folder in windows is located at (depending on version):

  • C:\Users\RUSER\AppData\Roaming\Blender Foundation\Blender\2.81
  • C:\Users\RUSER\AppData\Roaming\Blender Foundation\Blender\2.80


I tend to right click and send my config to a zip so it can be saved for later if needed. To restore it I can delete the new config folder and unzip the archive to this location to restore a previous setup.

Install from file will not work if the addon is present

For install from file to work you will need to delete the HOPS / boxcutter folders out of addons. This will ensure a clean installation.


Rename 2.8x folder for testing reinstallation

Alternatively you can also try a clean install by just renaming the 2.81 folder and trying install from file then.

This is the method I use to test every support issue involving installation that customers write me about.

  • renamed 2.81 folder to 2.81a so Blender won't load it.
  • loaded up Blender which loaded full-screen indicating prefs have been reset
  • installed Boxcutter / Hard Ops from file notice the hang when installing from file
  • configured prefs for general experience


By renaming the 2.81 folder I can test a clean install. Afterwards I can delete the new 2.81 folder and rename the old one from (a) to just 2.81 and go on with working without losing my bookmarks, save history, and recent file history.
