Terrain done

i have a fortress terrain thing that took me like 2 hours so far and i would like to know how make invisable platforms.

Invisble Platforms are in the doodads -> Bridges/Ramps section Just place them and raise them to be in line with the walls that you want to be walk able.

Is it multi layered? If so, then you will need some advanced stuff, stuff I don't know.

If by multilayered you mean more than one layer of pathing over the ame area, its impossable, the game dosnt support that, the only way to do it would be to use triggers to remove objects like bridges and replace them with the same model in the same place with no pathing, but if you have more than one unit walking the map at the same time you will have glitches whe ones on a bridge and ones under a bridge.
The invisable platforms are easy to do, but one mistake i made was the platformas are at the bottom of the chess cubes, not at the top, so i ended up with units walking half through the walls.
Also dont forget to use pathing blockers or units will be able to walk up onto the platforms from any direction.

i need more help i know how to raise platforms, but now i put pathing plockers around the area and i tested it and the units still walked right through the pathing blockers!!!! I used the kind that blocks ground, dead, and large and when i tested it with footman they still walked through....which pathing blocker do i use????

dammit i did'nt want to do this but showing the terrain is the only way to get replies this is supposed to be for a cinematic i trying to keep quiet and then bam
comes out and nobody knows about it, but no you had to make me post screenies to get replies wahhh!!! You see i am trying to make this place playable for a big battle wahhhh!!! :o

A dead apthing blocker is one that dosnt work, just use opathing blocker ground, nice pics though
