I was trying to have some fun with copying boxes on a slope/grip and noticed that my boxes weren't aligned as I expected. They did follow the slope but all pointed in a different correction.

Now when I made the same setup but rotated the slope 90 degrees around the y-axis, the boxes did align :shock:

What magic is going on here? Bugs? Lack of coffee, some special weird math stuff going on (or should I start reading the manual again :? )?

Cheers,

as far as I know, the object ( to be instanced ) should point towards the positive z axis.

I think it's the Z axis that get aligned to the normal.
If orientation matters you also need an up vector on the template.
