so first open HMT3 with D40 (the maw) and open the tab in resource browser effects and go to SCENERY\HALO_DESTROYED\EFFECTS\EXPLOSION_HALO
click on it and go to tag information on top and click the checkbox RECURSIVE and click save meta. make a new folder and call it bloodgluch meta and in that new folder make an other new folder called explosion1 (cauz yes there is an explosion 2). And save the meta there. We got explosion 1 exported. Now go in particle system in the resource browser and go to LEVELS\D40\DEVICES\POA_EXPLOSION\EFFECTS\POA_EXPLOSION here we got our explosion 2. Save the meta data recursive again in the folder explosion2. ok! we got the meta data that we needed to make a nuke!
But were just a the begin... dont jump now 
Ok so open bloodgluch in HMT3 and go to tools batch extract. In your folder bloodgluch meta, make a new folder called batch export. clik OK. good. now clik only export metadata chekbox. Click start batch extraction, it will take a few sec. When its done go in the folder of explosion1 (in windows explorer) and copy the folders that are in the folder of explosion 1. Paste all that in your folder batch export and click yes to all for remplace. Do the same thing for explosion 2 (paste folders from folder explosion2 in the folder batch export 
). Lot of folders heh? Still when your in your batch export folder paste a copy of bloodgluch. ok go back in HMT3, go to tools and clik rebuild map for the original map open the copy of your bloodgluch that we pasted. To the box that apears and asking you if you wanna fill the required files, clik OK. Now, at the bottom, to additional files clik add. go to your batch export folder and add theses file in theses folders: in your folder batch export , clik on scenery, halo_destoyed, effects. add all theses files. ok. Clik add again, go to levels, d40, devices, poa explosion, effects. add that file. done............. almost! 
. click BLUID. open the rebuilded map (bloodgluch.map.rebuild.map) in your batch export folder. ok now go to Effects in resource browser, and go to meta :SCENERY\HALO_DESTROYED\EFFECTS\EXPLOSION_HALO.

(EXAMPLE: WEAPONS\FRAG GRENADE\EFFECTS\IMPACT METAL) (TIP: ALWAYS CLIK SAVE ON THE SIDE AFTER EDITING META) BUT NOT OVER "WEAPONS\FRAG GRENADE\EFFECTS\EXPLOSION" AND "WEAPONS\FRAG GRENADE\EFFECTS\THROW". You HAVE to remplace the frag grenade metas if you wanna have the rocket work with a NUKE. goooood. now if u wanna have a nuke explosion with the rocket, go to WEAPONS\ROCKET LAUNCHER\EFFECTS\... and paste the meta of explosion halo over all the metas of WEAPONS\ROCKET LAUNCHER\EFFECTS\... , but NOT WEAPONS\ROCKET LAUNCHER\EFFECTS\EXHAUST, NOT WEAPONS\ROCKET LAUNCHER\EFFECTS\FIRE, NOT WEAPONS\ROCKET LAUNCHER\EFFECTS\FIRE ROCKET AND NOT WEAPONS\ROCKET LAUNCHER\EFFECTS\ROCKET EXPLOSION. ok almost done....
