combine 2 shaders

Question

I want to combine:
https://ibb.co/gZGVtKh and https://ibb.co/XXYVzPs to obtain: https://ibb.co/FVWWGgb

basically where the white in the radial gradient is, the voronoi shader's form needs to be seen. Can I do that in Godot? I have the code for both shaders, I just don't know how I can combine them .

Comments

You need to use the radial gradient as a mask for the voronoi. So by multiplying the result of the radial gradient to the voronoi, you should get only the voronoi where your gradient is.

Answer 1

Shader Combinations

Create a function for both of your shaders and return the output then as MrEliptik stated multiply the results

Example

vec3 radial_gradient(){
    return output
}

vec3 voronoi(){
    #your code here
    return output
}

void fragment(){
    COLOR = voronoi() * radial_gradient()
}

Tips

• The output var is what you would normally have in your fragment function as ABEDO = output or COLOR = output

• If multiply gives you unusual results try also multiplying by a fraction or adding instead

• If you're familiar with Visual Shaders this actually gets done for you automatically and the added bonus of seeing it live to make tweaks
