Hello.

As seen in the description, I'm doing a project where some atoms are light sources and cast a light effect (in practice, other atoms).

This light effect consists of two parts :
- a "light" atom;
- a "shadow" atom.

These light effects are all drawn on a backdrop PLANE_MASTER using KEEP_TOGETHER and BLEND_ADD.

The light source can be picked up by a mob.

When a mob carries a light source, I want, for the best visual effects, the "shadow" atom to glide smoothly with the carrier, but the light atom should perform discrete jumps and not glide.

This does not appear to be possible. Indeed, when one of the atoms gets given a "animate_movement = SLIDE_STEPS" (for instance), it looks like the other atom also gets it.

I am not sure if I'm misunderstanding how to use animate_movement, because I feel there should be a way to get around it.
