The fiery animation seems to be a bit slow. Looks like a laggy animation, IMO, but the flakes one seems to be pretty good. Prolly changing the FPS will mess up the flakes too, lol. I love the shading on the blade, though the bottom part looks weird, coz that radial gradient sticks out a bit.
i honestly dont see what you mean in regards to the animation, it runs very smooth to me and looked amazing in game imo. The smoke looked like actual smoke, was pretty proud how it turned out.
I never had any problems with how the animation looks. It's pretty good to me too..but it must be just me the first time 'round. I rather like the flakes more than the smoke though, for some reason. Pretty good job on this, man.
Keep up the great work Carlos.
