When you dont have internet access and you wanna use Roblox Studio, you can’t import assets, but with this plugin you can. I made a plugin that lets you offline import assets into roblox without any internet connection
The plugin prompts you to import file, once you have imported it, it will pop up in the program as this:
You get the Rbx Asset ID and theres a button that lets you load it into workspace
Install: Offline Files Loader - Roblox
I started working on this plugin a few days and more features are coming soon
(Please leave a rating on the plugin, thank you)
