Official Guide: Modding guide for Multi block objects
By Tomas_Volc
This Official Guide explains how to create a Multiblock object for Medieval Engineers

Multi block is a type of game object made of severl blocks connected together by the program. Most of the complex game objects, such as stone ramps or advanced battlements are done as multiblocks. Multiblocks allow you to create complex block shapes that can highly increase castle visual and even create a complete new architectural style (Gothic, Romanic).

Hope you will find this guide usefull. We are looking forward to see all the great mods you ceate.
In case something did not work for you, or a dev tool is broken, please leave a comment below.

Thank you
Example mod: Battlement Turret

This is the example mod that shows modding posibilities of multi blocks. Feel free to use the mod in any way you need, for creating your own mods.

What is MultiBlock?
MultiBlock is technique, how to create advanced objects bigger than one cube in the ME world. Main cube has 250×250×250 cm.

What is Mount-Point?
MountPoint are invisible plane near object, which make snap points for others models. If some side hasn´t mountpoint, other objects cannot attach.

1. Read first how to create models for ME: (optional)

2. Basically you should split your model to separate meshes. If your complete model is bigger than cube 250×250×250.

3. Split your model to separate meshes like bottom pictures:

4. Now, you need create collisions for your model. We use Havok physics SDK for Autodesk Maya and Autodesk 3ds Max.

4.1 Downolad Havok SDK:

4.2 Install SDK to your 3ds Max or Maya.

Havok SDK Toolbar in 3ds max.

4.3 Add collisions in hierarchy as childs and mesh as parent.

4.4 Select hierarchy with parent and childs and apply Create Rigid Body with Proxy(s).

5. Center all local coordinates to world (mesh and collisions) to zero (0,0,0).

6. Export your models as FBX.

6. Select hierarchy with childs and click to export:

6.1 Add components to configuration set:
Transform Scene
Create Tangents
Create Rigid Bodies
Write to Platform

6.2 Run Configuration

7. Open ModelBuilder and build your model. (Click the text for opening the guide)

8. Open DestructionTool and create destruction data. (Click the text for opening the guide)

9. Create and add definition about your models in .sbc file.

10. Set MultiBlock positions:

11. Add MountPoints definition to .sbc. Here is a simple picture, how it works:

How about adding the mult-block option to SE?

You guys are right, I am so sorry for the wrong guide post. I will add it to the Medieval Engineers guides.

Same engine, same methods.

Looks like a cool guide but this sems to be for ME not SE. I haven't gotten into modding yet but as I understand it there are some differences.
