Patches
Patch Objects
To follow this tutorial you can use the following Blender file that contains all the geometry necessary to create new patches on your own (either by swapping the textures of this sample or creating your own shape geometry). This tutorial will not teach you how to UV and texture, so pre-existing knowledge of these topics is required.
When you open the file you will see the following:
The highlighted object is the patch geometry, and the purple box is the collider. You can leave the collider as is.
Patches in RHS follow very simple rules:
No bones or rigging necessary
The world origin must be at backside (velcro) of the patch center
The patch must be facing in the rirection of Y+ axis
You can use morphs to make them fit the curvature of the objects they are attached to.
Morph Targets
In order to ensure the curving of the patch on rounded objects such as helmets and sleeves, you can add a "Curve" shape key and modify the geometry to fit with the sample above. The Curve key at 1.0 setting is the maximum curvature. The Basis key should represent your patch in fully flat position.
When you are importing your FBX into Workbench, make sure the Export Morphs import setting is enabled.
You will then be able to control the morph in the xob editor, but you can leave it at 0:
Prefab
While you are making your own mod with RHS: Status Quo as dependency, find Patch_Base.et in SQ and right click on it. Select "Inherit in 'MyNewPatchMod'". This should prompt you to create a new inherited prefab in your own mod. Edit this prefab.
In the InventoryItemComponent change the Name and Description values.
In the MeshObject component set the Object value to your newly created xob.
NOTE: If you are just changing textures and using the same mesh for the patches, then just change the material. You dont need a new xob for every patch.
In the BaseLoadoutClothComponent change the material overrides like shown below to your new materials. Change the Area Type value if necessary (just filter for Velcro to find all RHS velcto area types) depending on the general size of your patch.
Your patch is now ready to be accepted on RHS patch system compliant cloth items.
Receiving Objects
If you are setting up cloth items that should receive patches there are a few steps that are different for objects like Helmets, Jackets and Vests, because they interact with the AR inventory system differently.
The simplest approach for any item type is to inherit from a pre-existing RHS object that most closely resembles your new object.
Headgear
First add a RHS_ClothNodeStorageComponent and set it up in a similar fashion, changing values where appropriate:
In the BaseLoadoutClothComponent make sure you have Debug Worn Model value set to true when editing positions of velcro attachment slots.
Do not forget to turn Debug Worn Model to off when you are doen editing.
In the Slots array of BaseLoadoutClothComponent make an ew slot of type RHS_LoadoutSlotInfo. The name of the slot MUST be one of the following (Top Velcro, Left Velcro, etc.). If you name it wrong it will not work:
Use the following reference to set up the slot:
The Offset and Angle properties should be used to align the patch positioning. Load a patch prefab into the Prefab property to see it while modifying position:
Set the Name and Area Type settings appropriate for your patch attachment (name must be same as the slot name and area type must be one of the RHS velcro slot areas). Use morph settings to indicate how much the patch should bend if it has morphs:
Morph Value setting indicates by how much between 0 and 1 the patch will bend.
Vests
For armored vests the setup is exactly the same as for helmets but the name of the slot should be ChestVelcro.
Jackets
For jackets and other upper torso objects, the component structure is a little bit different:
The RHS_ClothNodeStorageComponent must be setup with above settings as a child of SCR_UniversalInventoryStorageCOmponent that is setup as follows:
The BaseLoadoutClothComponent is then setup ehactly the same way as for the Headgear:
Note that the slot names SleeveRight and LeftVelcro must be maintained for it to work.
