The walkmesh helper is a tool created by Zarathustra217 and apparently quietly slipped into the 1.05 patch.

I came across this post by TheStoryteller01 asking about making creatures hover above terrain. Grinning Fool posted some really amazing looking screenshots that he created using the walkmesh helper.

The walkmesh helper is a tool on the vault by Zarathustra217. Here's the description:

This is a simple package intended to make a builder's life easier. It consists of simple squared invisible placeables with a walkable walkmesh. When scaled, the Walkmesh Helper objects are handy to use along with Walkmesh Cutters (found under trigger) to have more control of the walkmesh. This especially is evident when using a combination of placeables, like several bridges. Place the Walkmesh Helper just above the walkable plane of the placeables, scale it to properly cover the desired area, and cut away with Walkmesh Cutters as fit. You might get the best result by converting the placeables to environment objects, but it shouldn't be required.

It is intended to work as an override, and doesn't require that the end users of your module have this package in place. They will still experience the effect it has on the walkmesh without it installed.

Here's an additional tutorial on using this that Feargus Urquhart posted in the developer blog:

As far as I can tell, the tool on the vault contains a flat plane and a ramp, while patch 1.05 adds two flat planes: a stone version and a wooden version (I'm guessing these are for the footfalls.)

Warning: At the time of this writing, putting the walkmesh helper files in your override seem to cause problems with the official walkmesh objects that came out in 1.05. Hopefully OEI will add the ramp objects soon.

For those of you looking to use it for those annoying house placeables that don't allow you to actually walk up the stairs, try the ramp with a scale of 2, 10, and 7. Getting in place can be a bit tricky, just because it is hard to see exactly where it is sitting. Try baking the area and viewing it with baked and surface mesh enabled and you should see a seamless yellow path onto the roof. I had pretty good results with house 1, but house 3 would only work if I created an additional plan on the roof.
