Hi,
i want to achieve that i itterate over all terrain triangles and randomly spawn som vegitation on top of it like grass patches and flowers and stuff.
i can’t just get the parts position and lookvector and move it a bit up since the traingles will be rotated in different ways so i though casting rays top down view and plant them when the ray hit a surface,

problem is it just doesnt work and i have no clue why i tried moving coordinates, changing blacklist/whitelist it just doesn’t wanna work properly.
