Fully procedural, stylized meteor made with geometry and shader nodes from a single object (Suzanne as the geometry nodes container)
This is still a shader-based effect as geometry nodes only helped in mesh placement / assigning materials
No image textures were used, rendered with Eevee
geometry nodes only helped in warping of the meshes, which are all planes:
