The addon DOES NOT include Lego 3D models. That wasn't possible due to copyright reasons. BUT the addon includes a link to my Mecabricks profile where you can download multiple building models for free which can be set up in just a couple of minutes to work with the addon (a video tutorial on how to do this can be found in the addon documentation)

3D LEGO scenes are very hardware hungry. Even though I added options to increase the performance inside of Blender, the more buildings you add to your scene, the worse the responsiveness will be. That's just how it is when you have thousands of brick models in your scene. So take that into account if your PC is not the fastest

If you created your own buildings in Mecabricks and want to share them, you can send them to me via [email protected] or send me an Instagram DM @kleinertino I will then put them on my Mecabricks account so they are available to every customer

Yes, this is based on my Building Generator tutorial series. If you think the addon is too expensive, you can get about 80% of what it does for free, by simply following the tutorials: https://www.youtube.com/watch?v=lQRQNwmZQFA&list=PLqnbcHYvDvhYOyPPj1KgxVfhdsiFpkDBl
