Hi, I'm experimenting with creating my own 3d models and shaders and I'm having issues with my lava effect shader. It's a very basic lava effect and it looks great in the sample window, but when I apply it to my Mushroom, (yes it is a lava mushroom), the Lava effect works on the stem but not the head of the mushroom. On the head it is stretched into long vertical lines. Because I am applying a shoddily made shader, to an equally shoddily made 3d asset, I'm not sure if the issue is with my shader of my model. Where am I going wrong exactly?
