Ice floes bridge

I'm making a map with frozen theme, and there will be a lake in it, that you'll have to walk over floating ices to get through it. I tried to make these walkable ice float using the icy bridge and changing its model to ice float, then I made some minor changes and tested it. But it didn't work fine...
The unit just can't get onto the ice float coming from the cliff. Besides that, when I put the unit directly over the ice in the editor and tested the map, it could walk off the ice and go to the water, what I didn't want at all.


Could anybody help me with this problem please? I REALLY need to do this walkable/bridge ice floats PERFECTLY!

Ok I haven't tested this but I will tonight. But something you could do it make a unit with the fly movent and flying hieght to 0. Make a few elevators and place little Ice Chunks. Or you could change the collision size of the doodad you want and put elevators under it. Like take a Glacier Chunk and change its parting size to .01 then scale it to the width of the bridge you want to make. Then place elevators underneath it and if possible, I forget, change hte vertex color of the elevator so it looks invisible. that should work. :D

p.s. - If that doesn't work have someone model a bridge of ice then import it into the WE.

It didn't work. :(

Please, does anybody have a solution to my problem?! I NEED this trick to complete my huge rpg campaign!
