-I will be demonstrating in Blender, **but you should follow along no matter what 3D modelling software you use.**+It isn't critical to complete everything in this step. So long as you make **any visual change** to Miriam's body and correctly export it as **.fbx** (reference the introductory tutorial) you should be good.
  
-Import SK_P1000.psk. Just a reminder for Blender import settings, uncheck the "Scale down" option before importing.+I will be demonstrating some common scenarios for editing the model. If you're not well versed in 3D modelling software I suggest you follow along to the end before moving to the next step.

 +As a reminder in Blender, adjust the units to "Metric", and "0.01". Remove all existing objects from the scene.

 +=== Deleting Part of the Mesh ===
  
 I'm going to make some obvious changes to the model so we know the update works. Hit the **Tab** key to enter edit mode. The entire model will be orange (selected). I'm going to make some obvious changes to the model so we know the update works. Hit the **Tab** key to enter edit mode.

 +=== Adding New Armor ===
  
 Now I'm going to add a simple piece of armor around her arm. Press **Alt + A** to delselect everything. Hit the number **1** key on the top of your keyboard to enter vertex selection mode. While holding the **Shift** key, select one vertex on the top and one vertex on the bottom of her arm, reference the screenshot below. Now I'm going to add a simple piece of armor around her arm.

 +With the cylinder still selected, hit the **R** key, then hit the **Y** key, then type **90** on your keyboard, then press **Enter**. This rotates the cylinder 90 degrees around the Y axis.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_add_armor_rotate_cylinder.png?nolink&800 |}}
 +
 +Press **Ctrl + R** on your keyboard, then move your mouse over the cylinder so you see a yellow vertical line like the screenshot below. Scroll up with your **Middle Mouse Wheel** to add more lines (I added 4). Then **Left Click**, then press the **Enter** key on your keyboard.

 +
 +This is called a loop cut, we've just added more faces to the cylinder so it can bend with the arm during animation.
 +
 +Move your mouse over the cylinder and press **L** to select it.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_paint_armor_select_cylinder.png?nolink&800 |}}
 +
 +Hit the **P** key, a menu will appear. Click "Selection".
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_paint_armor_part_cylinder_object.png?nolink&800 |}}
 +
 +Now press the **Tab** key to exit edit mode. You've just parted the cylinder into a separate object. This will be useful for transferring the animation weights to the cylinder automatically, so you don't have to do it manually.

 +**Left Click** on Miriam's body to select it. An orange outline will appear around it.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_paint_select_original_body.png?nolink&800 |}}
 +
 +Hold **Shift** and **Left Click** on the cylinder. The cylinder should have a bright orange outline, and Miriam's body should have a darker orange outline.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_paint_select_new_armor.png?nolink&800 |}}
 +
 +Press **Ctrl + Tab** on your keyboard. A menu will appear; click on the "Weight Paint" option.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_enter_weight_paint_mode.png?nolink&800 |}}

 +Click "Weights -> Transfer Weights" in the menu bar at the top.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_start_weight_transfer.png?nolink&800 |}}
 +
 +A small menu will pop up on the bottom left of the screen called "Transfer Mesh Data". Click on it to expand it.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_notice_transfer_menu.png?nolink&800 |}}
 +
 +In this menu, set:
 +  * "Vertex Mapping" to "Nearest Face Interpolated"
 +  * "Ray Radius" to "5"
 +  * "Source Layers Selection" to "By Name"
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_edit_transfer_menu.png?nolink&400 |}}
 +
 +Now hit **Ctrl + Tab** on your keyboard. In the menu that appears, click "Object Mode".
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_exit.png?nolink&800 |}}
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_weight_exited.png?nolink&800 |}}
 +
 +With this, you've successfully transferred the weights from Miriam's arm to the new cylinder piece of armor we've added, and it should move with the arm.
 +

 +
 +==== Wrapping Up ====
 +
 +Make sure in the Scene Collection you rename the armature from "SK_P1000.ao" to "armature". So Unreal Engine can read the file correctly.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_rename_armature.png?nolink&600 |}}
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_rename_armature_renamed.png?nolink&600 |}}
 +
 +On the menu bar, click "File -> Export -> FBX (.fbx)".
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_export_menu.png?nolink&600 |}}
 +
 +As a reminder, change "Smoothing" to "Face" and **un**check "Add Leaf Bones". Save the **.fbx** in the same folder as the **.psk** file you imported, with the same name.
 +
 +{{ :modding:modelling:tutorial_character_editing:tutorial_character_editing_export_menu_settings.png?nolink&800 |}}
 +
 +It probably feels like you've been through a hurricane at this point, but we are done with this step. Go to the next step for instructions on how to import into Unreal Engine. **The next step is the most important step.**
