One computer will act as a server, whilst other computer (as many as you want) will act as players.
On the server computer, launch minetest, and start a game where you will be hosting a server.
Create a new game first (in this case “jolin”)
Leave the Port field empty
Choose a name for your player (below we name it “sim”)
Tick the box “Host Server”
go on Mods and activate exportblock
Launch the command prompt on your computer and type “ipconfig”. Then press ENTER.
Your IP number is IPv4 (in this example: 192.168.43.125)
On the computers acting as players, launch minetest, go on PLAY ONLINE and enter the IP address of the host server. Enter a name for the new player, leave the “Port” field empty and join the game.
On the computer acting as host server, you will be notified when a new player joins the game
Use red wool blocks to build something of your choice. Beware that only red wool blocks can be exported for 3D printing.
Use the computer hosting the game to export the design. Go in front of the 3D object, open the communication window by typing “t” on your keyboard, and type “/exportblock”. Press ENTER.
Wait until the game returns a message stating the export was successful.
You will be able to find the .obj file in the directory “worlds” in your minetest folder on the computer hosting the game.
Launch Meshlab and click on File>Import Mesh.
If the object looks like the one you’ve designed on minetest, that means that everything went well. Otherwise, try re-export the object on minetest.
First, you will need to publish your object on Sketchfab.
Login on Sketchfab.com and upload your object.
Click on the “share” button to get the link to your model.
You can now reach this link on your smartphone and choose “View in VR”.
