Yeah I had it enabled for another project I was working on and it looked amazing before the fps tanked horribly on my gpu haha! Awee I think you did a good job just maybe make the scene a bit darker and add lights on the mech maybe!
Which program did you use to create the ik rig? Or do you just mean ik in unreal where it plants the foot where it should be? And awee it's just a jam be happy with where you go to and use what you learnt to build upon your next game :) I'm not so great at animation myself though haha (Mixamo is my friend).
Just up to the 4th! Just a bit exhausted tonight sorry!
