Concerning the forerunner bridge on extinction...

As you all know, I am currently working on a project codenamed Extinction2. Now, we all know how covenant light vehicles react to the bridge over the trench, and I was wondering if there was any way to fix it.

Help is appreciated!

How DO they react?

I never get far enough, cause I normally snipe.

When a wraith drives over it, it sits on the ground and you can't move.

Same with ghosts. If you boost over it, you fall through...

how can I fix it?

extinction didn't have a wraith, did it?

Extinction2 does.

Wraith works well as a defensive ground vehicle. It can hold the caves leading to red base and can be placed in startegic areas to stop attackers. though it does lack against the more heavy weapons and vehicles here, it is effective nonetheless.

The bridge, and other parts of extinction, glitch because it's bsp doesn't exactly follow the Sealed World Rules. The bridge by it's self does, and so does the terrain, but they overlap. Either the bridge needs to be stitched into the terrain, making them one object (best), seperated from it so they don't overlap (meh), or made a scenery so overlapping isn't a problem (uglier)

same goes for the rest of the map. Bungie's maps don't have free floating bsp objects in their bsp tags. They're all one piece bsps

Ah, I get it. It weould make it easy to just be a scenery tag, i think.

Of course, if what you said was best to make it one object, how would i go by merging them?

Sorry about the delayed reply

if it isn't already, make the bridge a seperate object, and make all it's edges visable. Optomize it's bottom because it's a mess

unhide all faces of the terrain
make all it's edges invisable
Hide all geometry around the bridge, except the canyon cliff's where the bridge will be connected
make all edges of the remaining unhidden faces visable
there will probably be just one edge on either side. Move those edge's verts to the bridge's outside corners, at driving-surface level
Alternating between top-view ("T") and front or side view ("F", "L", "R") will help you precisely position these verts
The cliff walls will likely run thrue the bridge's bottom at one or both ends. The cliff's 4 verts at each corner of the bridge have edges going down. Divide those 4 edges and position the new verts to the bottom corners of the bridge.

You now have 2 rectangles cut out on either side of the cliff.
Divide 3 more times at each end and match the cliffs verts to the bridge's

select the bridge
delete the faces at the ends of the bridge that are against the cliff

select the terrain again
delete the faces which are against the bridge. They hate the bridge. Delete them
attach the bridge
if in this process you lose uvw mapping and don't want to re-texture it, undo, re-select the bridge, apply a uvw unwrap modifier to the 'whole object', right-click the unwrap, cut, select the terrain, attach the bridge, select the whole bridge, paste the uvw unwrap modifier, and convert to mesh
but it's easy to re-texture. A simple box mapping will do fine

ok, on with it

Alt-x to make it all transparent
Right click, object properties, uncheck Backface Cull

select all verts and weld
select open edges
if any are found, either
1) 2 verts were too far apart to weld. You can select them and click Collapse, and they will become one
2) an edge needs to be divided. Then position the vert to the other vert and see 1) above

repeat untill no more open edges are found

thanks
