I thought I knew how to do this, but…
In short i’m after two tests, both use a sphere as a base object, to each i’ve added a hair particle system, then i’ve added an an arrow object.
One sphere I want them all to point out along their faces’ normal.
The other I want them to all point vertically up in the global Z.
I expected to be activating ‘advanced’ and then using ‘initial rotation’, but i’m not getting the expected results.
*** For 2, i’m assuming that just setting ‘object X’ or ‘object Y’, is the solution.
