Blocking volumes!!! --->help help help!!!

[MrCookie]

Yo!

rememer DM-Gateway? - Well in that level there is a section of nature - really cool looking scenery with cliffs and trees and stuff

Anyways Epic used some big big cliff-walkways meshes for this section
Now - these cliffswalkways are "NO COLLISION MODEL" - I know how Epic made it walkable though...They used blocking volumes.

But something thats been driving me bazoo and patzo is that when i look through Epics maps then i can see about 1000000000 blocking volumes.

What really dosent make sence is the fact that these blocking volumes block perfectly. - Im thinking that Epic must have like done this:

Take a mesh.

Then make a blocking volume.

And then used some kinda property for the volume so that it "fits" to the mesh...

So if anybody knows just how to do this then please let me know.

Thanks in advance.

The only way I know of to make blocking volumes is to edit the Builder brush to the shape desired and Add Blocking volume.

You just have to be patient to properly get the builder brush to align correctly using the geometry editing tools.

[AirRun]

you can import a .ase as a brush under the brush menu. (make sure to click on the builder brush after you import it as it tends to not update until you do that) Then you can use that to make a blocking volume.

I will note that I would not suggest doing this as it is the same as just colliding per poly on the static. I always find it best to fake it with simple collision even if that means walking through the static or slightly above it at times.

Just follow this tuto :

and choose "per poly" collision option for that mesh and voila ;)

does per poly work with no colission meshes?

What a good question :D
I don't sure to have test that method with "no collision mesh".
Need to test that ...

Well, for SM with no collision model, it doesn't make sense to go with per-poly collisions (as it consume more ressource & should be use only at the last resort). Just set them to "Blockallbutweapon" & add a blocking volume around the SM :)
