Description

Pipeline specific auto Static Mesh Set importer script in python to save time and enhance workflow.

How it works

Place all assets in a folder with following naming convention

SM_[Name of asset].fbx -> Static Mesh
T_[Name of asset]_BC.png -> Base color texture
T_[Name of asset]_N.png -> Normal Texture
T_[Name of asset]_RMA.png -> RMA Packed Texture or equivalent based on your Mater material in UE5
Run importer.py from UE Python
Select folder containing these assets.

Select folder dialog

Set folder path/name to import asset to under /Game/Assets/.

Path/name dialog

Post import.

Further modifications to fit other pipeline

The parameter name need to match the naming in python code. Any mask pack can be used instead of just RMA as long as the names are matching.

# Set Color to material instance
unreal.MaterialEditingLibrary.set_material_instance_texture_parameter_value(created_instance, "Color",
                                                                            in_asset_info.t_bc)

# Set Normal to material instance
unreal.MaterialEditingLibrary.set_material_instance_texture_parameter_value(created_instance, "Normal",
                                                                            in_asset_info.t_n)

# Set RMA to material instance
unreal.MaterialEditingLibrary.set_material_instance_texture_parameter_value(created_instance, "RMA",
                                                                            in_asset_info.t_rma)

Add the suffix to this array. Doing this will set such texture asset as mask automatically

# List of valid textures to set as masked on postfix
validMaskedTextureSuffix = ["_RMA", "_R", "_M", "_MK", "_AO"]

Match the suffix with the respective texture file name’s suffix

# Set asset info as per tex type
if unreal.StringLibrary.ends_with(loaded_asset.get_name(), "_RMA"):
    current_asset_info.t_rma = loaded_asset
elif unreal.StringLibrary.ends_with(loaded_asset.get_name(), "_N"):
    current_asset_info.t_n = loaded_asset
elif unreal.StringLibrary.ends_with(loaded_asset.get_name(), "_BC"):
    current_asset_info.t_bc = loaded_asset
