## This Post Import script automatically assign the

|
|
## `res://materials` directory.

|
## # How to use
|
|
## To you use it, you need to set this script as Post Import script
|
|
## on the file.fbx or file.glb.
|
|
##
|
|
## Your `materials` directory can look like:
|
|
## res://materials/iron_mat.material
|
|
## res://materials/glass_mat.tres
|
|
## res://materials/my_asset_kit_1/abc_mat.material
|
|
## res://materials/my_asset_kit_1/asd_mat.tres
