Moved to: [Building Plugin] LoopCut Utility
I have noticed that the basic loop cut functionality is missing from Roblox. It’s also a pain working without one, especially as a person who customarily uses this in Blender - hence I’ve decided to take the responsibility of quickly assembling a plugin for my fellow builders 
INITIAL SETUP:
I tried doing my best at keeping set-up and usage processes as straight forward & intuitive as possible. Most settings will be synced out of studio. Your only concern is to set-up appropriate key-binds to toggle & execute the loopcut, which you can do so by accessing the Roblox’s Shortcut Customization:
-
File > Advanced > Customize Shortcuts
-
“Loop” as a keyword
USAGE:
- Select the part you wish to subdivide
- Toggle loop cut using the relevant keybind
- Scroll up/down to increase/decrease number of cuts
- Execute loop cut
USEFUL FOR:
- Creating stairs and ladders
- Other cool stuff
TIP: Hold “Alt” to access parts within the model!
Source-code located on github - should you ever wish to view how this works under the hood or fiddle around with some settings.
