the shader attached is not working on Millumin4. I supposed because of Metal / Opengl...
the shader is a displacement map fx.
is there something i can change to make it work ?
You need to set the gl_FragColor variable, this is a good practice :
gl_FragColor = mainVideo(gl_FragColor, gl_FragCoord.xy);
We will see if we can improve this behavior, so the Metal conversion takes the out keyword into account (alllowing a secondary function to modify a variable by reference).
Thanks a lot Philippe :)
It's working ! ♥️
