I saw a demo on youtube with nice light-blue rockets, grenades ands nails models. Does anyone know how to get those?
In lastest ezQuake (I think after qcon though, so you might need a nightly build), you can just do /gl_custom_X_color, to set the colour of rockets, grenades, lg & nails. /gl_custom_X_fullbright toggles the obvious.
Sounds like one of milton videos.
If so you could download his textures from his twitch channel, (And his config if you want)
If you use nquake you wont get it to look exactly like that since nquake use some custom grenades and nail models. Move/delete models.pk3. Or maybe just make a new install with id paks + ezquake install and miltons textures.
