I love this mod so much it has led me try my hand at modding for the first time, so please forgive my ignorance. I am trying to add Waterfall to the Advanced Vernier Thrusters in the Kerbal Reusability Expansion mod. I think I have added the configs properly, but there is no material present. In the screenshots you can see the material present for the regular Vernier thruster (thanks @snkiz). I am using the same Waterfall template for both thrusters. Any help would be greatly appreciated!
