How to prevent instanced objects from colliding with other instanced objects?

YRdev

I am training a NEAT neural network and for it to work, It needs to collide with the terrain but not other instanced objects (same type) . How can I do this?

You can set the collision objects and layers so it can collide and see the terrain, but it cannot see itself. I think what you would need to do is have the objects be on layer 1 and the terrain on layer 2, and then set the mask for the objects to just layer 2 and NOT layer 1.
