TC 3.3.5 Vanish Fade Delay

Hi, just saw this video https://youtu.be/SCJSGBYGobk?t=20, it shows how vanish should actually be (with a little delay just for the fade) and I want to do that but I have a problem.

I looked into HandleModStealth but the thing is that yes, you can put a delay on the invisibility system in that function, but I don’t know how to put a delay in the “transparent” effect (the thing that makes you transparent).

Tried even to delete everything inside HandleModStealth, even HandleModShapeshift(just in case because there is something related to FORM_STEALTH), nothing worked but removing completely the effect (spellInfo->Effects[EFFECT_1].Effect=0) it doesn’t get you invisible obviously because that aura would have no effect but you don’t get transparent (I say this because it makes no sense that if I delete everything in HandleModStealth it keeps doing me transparent but if I delete the effect it doesn’t makes me transparent), so… where the **** is the transparent effect defined? XD
