[Solved] How to make always visible windwalk?

[WC3Wonderer]

Hi. I want to make an ability which allows ground unit to go through other ground units (not structures) and maintain ability to attack/cast spells.

1. Turning collision off does not fit because it allows unit to go through structures.
2. Ghosting does not fit because it not allow to go through other units and adds transparency.
3. The best option that came to my mind is Windwalk but I can't make unit visible to others and can't remove transparency.

Using the shift+click trick to input any values into object editor fields, set the 'Data - Transition Time' to -1.00
