After a bit of troubleshooting, I've managed to get a spec map working on Xenomorph.
Edit: After some testing, I got both Spec and Ref working. I made a gif to show it off.
I'm highly considering adding Xenomorph to my current projects, alongside Raptor, Wisp, Team Rocket's Meowth, and Zoroark.
Oh. My. Gawd. Yes, all of my yes! Ever since the first mention of Xeno in brawl I have been waiting, lurking...hoping for this day. I feel like it's christmas all over again
