Okay, I just need a little help figuring something out.

I want to make a three stage transformation skill. I already know what to with changing aura's and values using Eternity's skill creator. I can do everything except for one thing.
How do I change what the character looks like when they transform? This skill is for an x2m character imported with CACx2m, not regular CAC use.

What I want to do:

Stage 1: Black hair with no eyes (eyes similar to LSSJ), with Goku Black's aura (or villainous mode without the glowing eyes).
Stage 2: Gold hair with red eyes, with SSJ3's aura (essentially SSJ2 but with red eyes).
Stage 3: No change in appearance (like Potential Unleashed), except you have Golden Frieza's aura.

I'm pretty sure it has to do with editing .dyt files for the X2M character. But, no matter what I do, the character just looks like a regular Super Saiyan or Super Saiyan 3 with the new auras listed above.
On a side note, I also edited Trunk's CC Jacket's .dyt file to change the color for this X2M character. But, the color returns to being unedited when transformed. No idea why.

Any help would be appreciated. 

TL:DR How do you change hair and eye color for x2m character transformations?
