Currently, the default F3X building tools and import plugins are nonfunctional. Follow the instructions below to export/import your creations:
(https://create.roblox.com/store/asset/79170715686718/Buildverse-Export-Import)
-
Open Roblox Studio, install the Buildverse plugin. (The link above)
-
Open the plugins tab, Press Import or Export a file, then select the build you wanna import/export
-
A code will appear after you have exported the building you selected. Use this code to import your builds in studio or BYBAT or games supported by this system.
Important note:
This system only works in games that are supported by this plugin, some examples are Build Island and Whimsical.
Just like F3X, codes will still be replaced, so be sure to save your builds permanently in Roblox Studio.
