Hi everyone, I’m trying to change a mesh material by clicking on a button. So I have three buttons on a HUD that are setting an index number for a material array when clicked, although it changes the material, it only shows me the default squared material. I’ve tried to plug a simple variable containing a material in the set material, but I’ve had no better results . I’m trying to make it work for mobile. it works fine with the shader model 5.So i’m beginning to think the set material is not optimised for mobile ? Here is the object’s blueprint. Every comments would be most welcome. Thank !!
