Yep, download PE3 from Stalkerfiles and you will see how.
I used AMK bind_monster script, but made a standalone version that does not need other AMK scripts. You then create a section for the mutants particles, and a reference in the mutant file to the particle section.
Look at the bind_monster.script, config\creatures\particles.ltx & m_controller.ltx and mutants.ltx - in the ltx files I added a comment like ;
_ecp so you can see the new lines I added. The particles.ltx is a completely new file, so I "#include" it from monsters.ltx.
AMK did it originally with their Electro chimera, and
Nightwatch helped me understand how it is done.
