Adding a Rubber/ Oilskin Type of textile (leather)
I found it strange that you could only make boots and shoes (Vanilla Expanded for example) from Animal-Products, which didnt really fit my High-tech, vegetarian, Techbro Corporate Run.
So i made a rubber textile. inspired by fisher oilskin Clothing, its bright yellow. Made from Cloth and Chemfuel, IIRC the stats are copied from plainleather.
