Stylized Smoke Shader
how to use :
add the mesh to your particles
set the vars as you please
to get the mesh and a ready scene for you to test here is the Github link:
https://github.com/Loop-Box/Stylized-Smoke-For-Godot4.5.git
The shader is used as “material_override”
if you want your smoke to have shadow just:
comment the light function , so from this :
void light(){
}
to this
//void light(){
//}
