injecting scen into coagulation???

[ErrorCode]

i want to try to add the scene from the sp level 08b_deltahalo the halo disarm explosion into coagulation as an explosion effect for a chain spawning weapon i have built. i used insolence to drag and drop the halo_disarm into coag but i cant figure out how to set it up to work. i tryed using it as an impact effect or what not. i know theres a way to get that explosion ive seen it in a coag pic b4.
