Impact VFX

This is a minimal Shader to create an impact VFX by running a texture along a circular plane. You can control the cutoff alpha, the speed and Y-coordinate texture repetition. Note that a circular plane mesh is required and the UVs should look like the blender screenshot for it to work properly.

Shader code
shader_type spatial;
uniform sampler2D tex : filter_nearest;
uniform float speed;
uniform float stretchY;
uniform float alpha;
void fragment() {
	ALBEDO=texture(tex,vec2(UV.x*stretchY,UV.y+timefactor)).rgb;
	ALPHA=texture(tex,vec2(UV.x*stretchY,UV.y+timefactor)).a;
	ALPHA*=UV.y*alpha;
}
