Changing the outline shader on raycast collision

ubik

Hi folks! I am new to Godot and need some guidance :'(

I set up a raycast so I can pick up objects; it happens when the ray collides with one and I trigger a key event. So far, so good!

Now, I am struggling with making an outline around every object that collides with the raycast. So far, I already got my outline shader material. But how can I turn it on and off for the object the raycast is colliding with?

Extra question: is there a way that the raycast can input the material dinamically into everything it touches, or I rather have to configure the material for every object?

Got some tutorials on YouTube, but they don't go beyond the shader being active all the time.

Thanks for the hints!

The function is called "set_material_override". You call it on the mesh you want to have the special shader, and then set it back to normal afterwards.
