thx in advance I have two planes, one with a vertical tree image texture and one that is flat 'ground'. I want to use a particle system to place the trees on the ground. However the hair emitter has the tree the wrong way on the ground. I do not see any particle system ways to properly orient the tree on the ground. Before I changed the Render from Path to Object the 'hairs' had the right orientation. Surely I'm missing some basic thing. It appears that older versions of blender had rotation controls for the hair that I cannot find in 3.0. Also all of my objects have all transformations applied and neither object is being effected by any modifiers.

Particle systems use different orientation than Viewport (because reasons)
Simply rotate the origin point of your object by 90 degrees so they match
