Weapon Replacement Guide - KarbonAKitt/CVWiki GitHub Wiki

This will be a pretty straightforward guide to make model replacement for weapons.

Tools needed:

• umodel https://www.gildor.org/en/projects/umodel
• The psk importer https://github.com/Befzz/blender3d_import_psk_psa
• 4.18.X Unreal Engine https://www.unrealengine.com/en-US/download
• Unrealpak to make a .pak
• a working model to replace a weapon with
• a Normal Map, an RMT and Albedo textures

1.- First open umodel and extract the model you are going to replace, this will create a .psk file in the folder of your choice. In this example we are going to replace the Black Sword weapon.

2.- Open the .psk in Blender (or any modelling program you are comfortable with that can open .psk files and export as .fbx)

3.- Import the model you want to replace your weapon with, in this case we are going to replace it.

4.-

• Select the mesh you are replacing, go to edit mode and deselect all
• Go into OBJECT MODE
• Select the original mesh
• Select the replacement mesh
• shift + right click on the original weapon mesh
• ctrl + J to join the meshes
• press TAB to do into edit mode
• press ctrl + I to invert selection (at this point only the original mesh should be selected)
• press X to delete and then press V to delete vertices

4.1.-

• If you are using Blender 2.79 you will more likely end up with 2 different UV Maps after merging the meshses, delete the empty UV Map or you will end up with a texture-less, white model.

5.- Export as FBX with the correct settings:

6.- Open Unreal Engine 4.18.X and create a new project.

7.- Import the FBX into unreal engine with the correct import settings:

8.- Create the appropriate references, drag the textures in the correct folder path in unreal engine:

• PHAT: Physics Asset
• Shadow: Physics Asset
• MI: Material Instance
• PPABP: Animation Blueprint

9.- Double click the mesh file and fill the blanks inside:

10.- When done click

• SAVE ALL
• Go to SETTINGS in the TOP BAR
• Go to PROJECT SETTINGS
• Go to PACKAGING
• UNCHECK USE PAK FILE
• Go to FILE -> PACKAGE PROJECT -> WINDOWS -> Windows (64 Bits)
