You should remove the geoset itself with its materials, from what I understand, you only removed the material layers
I have never worked with modelling in notepad, so I will tell you how to do it with Magos model editor or Mdlvis
In Magos Model editor:
-Ctrl + Left click on the Hero Glow, the selected part along with its geoset will flash
-Go to Geoset manager, you will see a geoset selected, this is the geoset you just Ctrl + left clicked on
-Remove it
-Go to material manager, the material of the Hero Glow's geoset will be selected
-Remove it
-(Optional) Go to node manager, then remove the "hero2", "hero3" and "hero04" bones, these are the bones of the hero glow that you removed, and now they serve no purpose other than increasing filesize
In
Mdlvis, its much easier:
-Check each geoset until you find the hero glow geoset, I recommend that you then uncheck the other geosets so you don't remove any other meshes accidentally
-Select the hero glow then delete it
-(Optional) Go to sequence editor, remove the "hero2", "hero3" and "hero04" bones, same reason as above
