how do i remove the glow from a model

how do i remove hero glow and weapon glow from a model?

You imo can open the model in wc3 model editor and delete glow material. Then you just import the modified model and the work is finished :)

PS: You can get the editor on wc3sear.ch

You thought about the War3 model editor by Magos, right?
Any way, here's the link: magos.thejefffiles.com/war3modeleditor
