Hole Texture Transition
A simple texture transition for your games. Use the shader in a Color Rect and add the texture of your preference. You can animate it with animation player or other methods.
Texture recommendations:
-Transparent texture, except for the silhouette.
-Don’t let the silhouette touch the edge of the texture.
Feel free to optimize this shader! 🙂

Shader code
shader_type canvas_item;
render_mode unshaded;
uniform sampler2D hole_texture;
uniform float screen_width;
uniform float screen_height;
uniform float scale :hint_range(0.0, 100.0, 0.01);
void fragment() {
float ratio = screen_width / screen_height;
vec2 custom_uv = (UV - vec2(0.5)) * scale + vec2(0.5);
vec4 textura = texture(hole_texture,custom_uv);
float dist = distance(vec2(0.5, 0.5), vec2(mix(0.5, UV.x, ratio), UV.y));
if (scale < 95.0){
COLOR.a = step(textura.a, dist);
}
}
