could someone help me out since a few changes i am unable to do a navmesh check to find out if there are troublespots. whenever i do a navmesh scan my geck seems to freeze up .
when i load the mod i created i get a message that there are bugs in the mesh but i cant do the scan so i find out where the bugs are and how to fix them.

'freeze up'.

How long did you wait?
If you have a large navmesh it can take several minutes. If you have a slow computer, it could take even longer.

Try a little patience first, then report back if it still does not work.

patience is not the problem justthat when i use the test nav mesh option nothing seems to happen even afther 5 to 10 min while the mesh optimisation works very fast

Ok I think your clicking the wrong buttons. It sounds to me like your using 'Test navmesh' which is used to show you the path an NPC would take between two point in your navmesh. Therefor, you click it and it goes into that mode and doesnt appear to do anything. What you want I think, is to click 'Find triangle' then click check navmesh. Then it should run over it real fast and look for problem triangles. This is the feature I believe you want to use.

Gunmaster is correct, the "Test Navmesh" button requires you to then left-click twice in the cell - the first time at some starting point and the second time (I think you have to double-click the second time, so total 3 mouse clicks) on the destination of the test. The GECK will then draw a large green line across your cell showing you where the engine would direct the NPC in the real game - allowing you to see if NPCs will go over your Navmesh the way you want to.

You don't have to do this ever, it's only for specific testing of navmesh paths that you worry about.

To "test" the Navmesh to make sure it's okay, just use the 3-button combination of:

1. Find Cover Edges.
2. Balance for Optimization
3. Finalize Cell Navmesh.

That's all you should be doing when your done Navmeshing and want to make sure its okay and done right. The GECK is hanging because your starting a Navmesh Test and never correctly finishing it, so the GECK is actually still waiting for your input.

Luck,
