Here's a good way to start writing a tutorial, just start writing out information you know on things and group them together. Once you have most of it done, you just have to rewrite it a little to be a bit more of a how to.
Well, I can try.
The reason to "Freeze when grab" and "Freeze at grabbed" Glitch
The problem that are causing is because you model has a very bad bone tree and are NOT simile to the model you have replace.
this might be a rel/tabuu related thing but I haven't found it
lets look on a few models bone tree.
This is model on Olimar, Pikachu and Pit.
as you see on Olimar, he has no bones before TransN and it makes his bonetree go to "1"
On Pikachu, you see he has his YellowEyeN before TransN and make his Bonetree go to "2"
and on Pit, he has both YellowEyeN AND FacePattern and make his Bonetree go to "3"
Lets say, If I replace a model with it's bonetree with "1" over olimar, it will NOT freeze when grabbed and grabbing (but I think you need to set where the ThrowN are in Tabuu anyway)
But if I replace it with a bonetree with "2" OR HIGHER, it will freeze when grab and grabbing.
it's same on everyone, it need to be THE SAME to fix the glitch.
1 = 1
2 = 2
3 = 3
also, if ANY BODYPART bone are before the "real" TransN bone, It will be in the middle of the stage!
how to fix is you need your models bonetree. it's pretty big on that and dont know how to write D:
this is some example on fixes I mean.
Toad over Yoshi with his bonetree "1"
Wheelie fix over "Lucas" with his bonetree "2"
Petey Piranha fix over Pit with his bonetree "3"
read the note
well, this is a beginning.
