How do I get rid of footsteps?

is there anyway to turn it off, or change maybe?

Im pretty sure the only way u can get rid of footsteps is to...Change Terrain.. or make the unit hover over the ground just a tad... so it stills looks like he is walking..

I think it can be made easilly if you want to remove all footsteps. Search in the mpq for the texture that is used for footsteps (but I don't know where it can be), then replace it with a new one (that is, import a new one with the same path)on which you'll have made the footstep transparent with alpha channels.
I have never tested it, so I don't know if it works or not, but it's what I'd do.

As far as I know footsteps are a part of the model itself. If you want to remove/change/add footsteps to a unit you need to extract the model, do the remove/change/add, then import it in again; and that will add some size to your map.

Yeah, to remove them from one single model is really easy : go to event objects, find the corresponding ones (their keys belong to the interval of the walk anim and their name is something like "ftpprt" or something like this, anyway when you see the name you can with a little imagination recognize "footprint"), and remove them and their pivotpoints (don't forget to fix the following objectid's) or just change their keys to a key that doesn't belong to the interval of any of the model's anims. What I suggested before was a way to remove all footprints of a sort, but I don't know if it works.
