I doubt that that is possible, considering that the "terrain.lvl" file would have to be "Hacked" since that is the file that is storing all of this information.The ideal fix would be to replace (batch process) the stock worm fence segment with two scaled down (0.5) and linked worm fence segments.
An how would anyone Code the "Batch Process" to move the fences to the left or the right when a lot of them are just randomly placed where the "Map Designer" thought that they should appear.
I don't think that you are understanding the value of the "HexEditor" in this situation.
As of Now, you have to Open every single fence and change the first two values which takes a lot of time.
If All of them were reduce in size, You would save hundreds of hours by just moving them either left or right too reconnect them together, and then just "Duplicate" some-more to fill in the gaps.
I use the "XVI32" since its the first one that I started using years ago, but I think that All of them do just about the same thing.I see available Hex Editor apps on line. Do you have a recommendation I can check out safely?
Try to find one that doesn't have an Expire Date - You know, No Trial Version!
