Does anyone knows how to add a custom glowing iron sight to a ported weapon, like made of tritium.
What do I need to do in APE ?  ???

lit_emissive
you can see some examples in modtools, typing tritium in APE filters

Thanks for that. I have found some mr6 examples, but still I don't know how to apply this material to a custom gun.

Edit: Alright, that was hard for a guy that almost doesn't know a thing about APE, but i managed to do it.
If someone is interested, you have to change your gun's material type to lit_emessive, then add emessive map, edit it by erasing everything expect sights, add some color and tada...
