I want to process an asset library that contains four assets, one for each season per Blend file. I want to change the material properties for all objects in the Blend file based on the material name.
Now I want to change the material properties based on the season and the material itself, the name of which is the text after the last underscore (e.g. "trunk" or "rock").
The changes are as follows: If the asset contains "_summer", skip it. Summer assets have all 3 properties set by 0 as default. If the asset contains "_autumn" set input 2 to value 1. If the asset contains "_winter" set input 3 to value 1. If the asset contains "_spring" set input  to value 1.
