Can't get pathfinding to detect trees

This sounds like a basic issue I should be able to figure out, but I can’t get trees to be detected with terrain. “Show Surface” shows the surface overlapping the tree region where on other maps it bounds the region in question.

The trees are part of the terrain but have colliders on layer default


Example tree, interior of the tree is all blue (the surface)



That’s odd. Are you sure the trees are in the correct layer so that they will be detected?

Forest and trees are on the default layer. This happens on every level

Do you think you could upgrade to the latest beta?
If that doesn’t solve it, would it be possible for you to share an example project which shows the issue?
