I thought I could make easy cacti by painting cactus leaves on the ground then painting smaller leaves on the big leaves, using Foliage tool which has option for painting Foliage on Foliage. However this doesn’t happen. The meshes are Static Mesh Foliage and have collision. When the Single Instance Brush is on the leaf it has a sphere, just as it does on the ground. (see pic) When ‘Collision Presets / BlockAll’ is set to ‘NoCollision’ goes away. So it recognises it has collision.
What am I doing wrong?
FIXED IT - in the Static Mesh Foliage Settings, Custom Navigable Geometry has to be set to off
