How to make a sword glowing

[undone lava]

Hello, I'm trying to get a sword model glowing. If there any right way to do it and somebody could help I'll be grateful. Maybe I could use shaders settings or something

do you have a "lightsaber_bladecolor_02" that is applied to the model?
Emmisive textures are not applied directly to a model but are rather sorta "overlaid" on a regular texture

this is done automatically by mods based on the "_e" suffix

I tried to just make a copy of a blade texture with a _e suffix and just leaving the model ad is but didn't work as well

well that sounds like the correct way to do it
are you able to see if other packs with Optifine-style emmisive items work?

That will help inform if it's something with your shaders or with your model
