How do I make material made from this shader cover more of the mesh?

I’m very new to using the shader graph, in fact this is the first shader I’m making without directly following a tutorial. I would appreciate some help. I’m trying to make a meteor for my game, and this is what I came up with (it’s somewhat inspired by what I learned following a tutorial on how to make trails).

I need help figuring out how to control which portion of the mesh this covers. Right now it looks like on the image bellow and covers maybe 1/5 of the entire mesh. I want this fade to only happen at the end and most of my meteor to be this red and orange gradient.

From my understanding I should be using a Position node set to Object for that, as well as a Split node, but I’m not sure into what exactly I’m supposed to feed their output. I’m sorry for such a noob question, and I greatly appreciate any answer I get from you kind strangers!

Currently, your noise and textures are projected using UV coordinates. So the way your UV coordinates are set up on the model will control how the effect is applied. So one why to get what you’re looking for is to adjust the UV layout on the mesh so that more of the UVs are pushed toward the bottom of the UV space.
