Thanks both of you.
So, I started from the beginning.
Open brawlbox, open luigi's fitmotion, ????????
I really don't get that next part. Maybe I should just be an animator after I do this. I used to animate stick figures but this is different. I also used to have Fighter Maker 2 but my idiot friend sold it. What the f***!?
I guess it's time I stepped in.
1. Open FitLuigi##.pcs or .pac. (Yes, open up any Luigi texture that you have).
2. Open ModelData[0] > 3DModels[NW4R]. You should see see a gray box that has MDL0 written over it.
3. Right Click that grey box and then hit preview.
4. Use the scroll wheel on your mouse to zoom out until you see your model. Right click and drag to move it around ;and hold ctrl+right click and drag to rotate it.
5. Expand the right sidebar. At the top right you should see something that says "External File;" and Load, Save, and Close underneath.
6. Click "Load" and select your motion.pac.
7. A list of animations should appear in the box in the right side bar. Select one and it will load the animation.
8. Expand the side bar on the bottom (you might want to enlarge your window), and you should see Speed:60, Loop, "Play", and Frame:.
9. Hit "Play" and it will play the selected animation.
THE END.
Thanks but I already figured that out.

Now that I fixed the attacks I need to use PSA to do the hitboxes.... Help?
