GGMAX Bug - DEVTEST - Terrain Barriers Are Back

[OldFlak]

A long time ago we had an issue with MAX creating invisible barriers in the terrain, around the same time we had the fall through terrain bug.

Well MAX has got the terrain barrier bug again. Here is avid that demonstrates the bug, and the solution to fixing it.

This level has never had that issue, and only recently decided to create the barrier. My guess is it is a result of having edited the terrain under the main building in the scene, it has a giant hole under it, that I made a tad deeper.

No doubt near impossible to reproduce reliably, but it should probably still be looked into again.

Actually found it fairly easy to reproduce - dig a large whole in the ground, and walk around it to find the barriers sometimes they be huge!

It is actually much worse than I first thought. Trying to fix it by smoothing out around the area just shifts the problem elsewhere. Not ice in this video that it seams the player is walking over an invisible mound before the barriers become apparent. That is exactly what occurred when we had this issue ages ago.
