Unit Transparency

Hi. I'm making a spell where each rank makes you 25%/50%/75%/100% transparent. My friend told it it there was a spell like it in dota or some other nameless aoe map, so it is possible. Just wondering how it can be done.

Thanks in advanced.

ps, I have WEU.

I don't believe it's possible. Either you're invisible or not, but why would you want a spell has different levels of transparency? It doesn't sound like it will have any impact in gameplay.

If it is just for the look, then modify the alpha vertex color, that should be quite easy.

I took the liberty of making the trigger for you in GUI since it is very simple.
Of course you would just change "Channel" to your ability.

Try to have a refrsh trigger, like if u type smth, u cast a dummy spell on the invis unit, and change the vertex colour of it again, because if its a hero, it may revert back to its original transparency after death and revival

Wow, thank you very much for the quick replies and answers!

Yes, if the unit is slowed or poisoned, its colour is changed, and its alpha is reset back to 100%.
So you should be aware of that.
