I saw this Video https://www.youtube.com/watch?v=EbAdconaRJo&list=PLMZekPLzM11K1XD3PS983aALEqlz0xqs5&index=22 but when I export it in any export file it doesnt work and is hidden. How to export the material or the object with the Material?
As far as I am aware, Blender’s procedural shaders are not compatible with Godot’s OpenGL shaders (as of 2021). You would need to learn how to write shader in Godot’s shader language (or visual shader language) that achieves a similar effect.
Good resources to learn shader writting are Shading language — Godot Engine (3.0) documentation in English
as well as https://learnopengl.com
Youtube tutorials can also be of use.
