Morphing abilities allow changes in collision?

Do morphing abilities allow changes in collision?

I have a hero who's first level ability is supposed to allow him to plung into the earth and move beneath the suface. I need him to be able to pass through units while in this state.
1) I have tried setting collision size to 0. Which does reduce the area required for him to pass, but his movement is still prevented by large collision sized units.
2) I have tried setting movement typ to flying. Which works perfectly as far as functionality, but flying does not allow you to set movement height to less than 0. (You can in the editor but ingame the unit will allways stay above the terrain. Im using Hover)
3) I tried Ghost, but his movement is still prevented by large collision sized units.
4) I tried burrow, but this disables all abilities while in that form.

I am about to try Ghost(visable), but to be honest I don't see what difference that will make...
If anyone has any ideas post Im.

There won't be anyway you can get it beneath the surface, that I know of. May as well change it to flying with 0 height, and something like a burrow model. Changing something to collision 0 does not turn off collision (which you can do with triggers).

Set the flying height, AND the minimum flying height to negative. But then you won't be able to see the unit, so it's probably not the best idea =\

You could replace the unit's model with a rock projectile, to get the Bugs Bunny tunneling around effect. Also I usually find collision size 1 works better than 0 for some reason.

Can you somehow use windwalk for you purpose?

Actualy hover allows you to set hieght to a negative, and it will work ingame.

I had already set Min height to a negative. It doesn't work, fly simply will not let the unit below ground
Although the rock projectile idea is good, I think Im going to do that.

mmm, nah. I want a new aura ability added and the hero abilities disabled when used, so a morph would be best.

Speaking of which, I changed in Gameplay constants 'Morphing Disables Alternate abilities' to true but I can still use the hero abilities. Is there a way or a specific morphing ability I can use that will disable the normal hero abilities while the hero is in it's alternate form? Also I was thinking as a work around I could simply set the alternate forms mana to 0, but Im not sure if this will work. I once had different starting and growth settings for hero attributes, str agl int, in the alternate and when he changed form it permanently changed the attributes to match the alternate...

I would just morph him into a flying unit with no valid model, mess with buffs/triggered SPF to get it looking reasonably pretty (burrow type effects), then use tirggers to disable all his hero abilites when he morphs and re-enable them when he morphs back.

Disable pathing through triggers to make him pass any unit.

I guess i forgot to mention in the first post (sorry ) I wish to do this without triggers.

Im going to do fly with a stone projectile model. Now I just need to figure out why the abilities won't disable when morphed.

Once you try all the object editor ways and they don't work, you'd have to try triggers eventually

Lol, I know. I just like to explore all options before going to triggers/jass. I just don't like doing something that way if can be done through OE means.
