Prefab is a collection of functional and aesthetic buildings that you can place into your world instantly! With our instant houses and structures, you can skip over the time consuming job of landscaping, and trying to build without a creeper undoing your work. Our preview function lets you see the structure in the world, and move through a projection of it in real time. Just pick the place you want to put it, and the Prefab Blueprints do the rest! Whether you haven't got the time, patience or will, we've got structures that are guaranteed to please some of you, but not all of you. :)
Note: Since this has been asked so many times in the past. There are no plans to create a feature for custom blueprints or loading custom structures outside of the ones provided by this mod.
This functionality already exists with Structurize and we highly recommend it.
This is the Fabric version of Prefab!
The Forge version of Prefab can be found on CurseForge
All structure GUIs include a "preview" button. This will create a shadow structure in the world for you to see what it will look like when it's placed. This will give you the opportunity to make sure that you have enough space for the structure or to make sure that it will be placed where you want it to be placed. Block facings for fences, torches and other similar blocks will most likely not have their proper facing when rendered in this fashion, they will look correct when placed.
Note: This functionality was adapted from Botania's Visualize functionality. The mod info and source code has been updated to state as such as well. botaniamod.net/license.php.
