How do I remove special effects on models?

Ok, the title says it all. Special Effects, like the Kobold sparkling from the stupid candle on his head, or the beasmaster spell slam (I think) or maybe the Spell Breaker thing that appears when he attacks?

Edit the model, remove the geoset, particle emitter, ribbon emitter or whatever it it is you want to remove...

Or change its visibility to 0, but removing would be much easier and better.

Removing is better. And with all the MDL editing tools on offer these days, it's even easier than before to carve bits out.

remenber that some of them come out of event objects and attachment points too,

remenber that Attachment points with word Sprite can spawn effects like dmging effects or fire effects like the blood mage.

and remenber the different types of Event Objects:

FPTxyyyy -> Footprints
UBRxyyyy -> Uber Splats.
SPLxyyyy -> Blood Splats.
SPNxyyyy -> Spawn Objects.

and not spawn effectable SNDxyyyy -> Sound effects.

I recommend deleting everything by War3ModelEditor's Node Manager. If you still want to use Notepad :) don't forget about ObjectIDs.
