[Solved] Need help to see throught trees

[Herod]

Those green boxes are dummies trees, it is to destroy arrows or other projectiles ( and simply dont pass throught it).

But I´ve noticed that If I set occlusion height of the dummy tree to 0, you can see throught it, but the projectile dont colide. (im using missile gui system)

If I set occlusion height to default the dummy tree blocks the arrow, but Cant see the models. Any suggestion what need do now

[solved] I´ve copy pathing blocker, set occlusion height to 300, and add Fat line of sight, now the blocker blocks projectiles, and the doodad can be visible
