Finally an alternative to Sproily and DiamonD's Controller
Maestro Fénix's Alien Controller
I was disappointed that after all these years only Sproily and
DiamonD did a new model, but I'm not a fan of it ( because not only due the
noise and the orange tone that have their textures, but also because it has zero detail at the
brain), until BMS did their own ( and then Human Error did as well,
but lets gonna say...is too different ).
So, I just took the original
model, raised the polys, did new UV maps, made bigger the textures with
Waifu2x ( such blessed tool ) and rolled all of them into three-four
textures. Also added eyes and made the prong part of the brain to glow ( although in vanilla HL this effect will be affected due the environment effect ).
The only negative aspect is that due GoldSource not tolerating multiple vertex per bone when rigging, there are times where it may look bad ( mostly the dead animation, but it may happen in between frames ).
Feel free to use this on your own mods / packs or even to further improve it, just credit me.
An skilled 2D artist would take advantage of the new UV maps to make fully new textures of it, a thing that sadly I have not yet the skill to pull it off with professional results...
