So after some testing, it seems to be an issue with the striker gear set itself.
It doesn't want to apply the full shader. It just applies a white, except for the kneepad caps. Those change color.
The Full Shaders work with everything else fine.
Hey Ubisoft, I know it's not major but maybe you can fix one of this seasons gearsets to be able to use one of this seasons shaders? 🤷*♂️ 🤞
