Prefab
Creates ways of providing instant structures
Quick answer
Which Prefab release should I use?
prefab-1.6.5.17.jar targets 1.16.5 with Forge. The project page does not say whether this file belongs on the client, dedicated server, or both. 1 required mod needs a matching file.
Where it goes
Is Prefab required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does prefab-1.6.5.17.jar need?
prefab-1.6.5.17.jar. Change the file and its required mods may change too.
Install Cloth Config API (Fabric/Forge/NeoForge) first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Prefab add?
Whats New?
In order to keep development time down as Minecraft 1.21.1, we will no longer be supporting Forge. We will continue to support Fabric and NeoForge.
Discord: Want the latest news on Prefab? Want to yell at us? Want to share your creations with other likeminded players? We've got a Discord that you can use to reach out to us with problems, solutions, ideas, musings, thoughts, commentary and anything else you may want to share with us and the community of Prefab users. Just remember to keep your contributions constructive and friendly for all ages.
Let's build something cool together! https://discord.gg/qpkPnfays5
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. :)
More structures are being developed and added as the mod progresses (and we have ideas/time!), so be on the lookout. Feel free to share requests and constructive criticism in the comments.
**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](https://www.curseforge.com/minecraft/mc-mods/structurize) and we highly recommend it.

### **Blocks and Items Added**
For a complete list of blocks and items added by this mod, please view the CurseForge Pages Wiki here:
[Home Page - Pages - Prefab - Mods - Projects - CurseForge](https://www.curseforge.com/minecraft/mc-mods/prefab/pages/home-page)
### **Structure Preview**
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. [http://botaniamod.net/license.php](http://botaniamod.net/license.php).
**Note**: Make sure your graphics setting is set to "Fancy" otherwise this functionality will not work

### **In The Works**
Working on updating to 26.1 but it is slow going since we never upgraded past 1.21.1. We will be updating in stages, so you will see releases for some intermediate Minecraft versions (like 1.21.4!) before 26.1 so stay tuned!

Feel free to use this mod in any Modpack, we just ask that you please link back to this mod page in your description.
