I’ve attempted to follow two tutorials where rocks are used in particle systems - in both cases, my rocks end up floating in the air, under the ground, all sorts of places but sticking to the ground! The tutors never make mention of this - theirs simply work without comment. With some messing about, I’ve found that there seems to be a relationship to the pivot point and/or the origin, as to how the replicated instance conforms to the emitting base, but haven’t quite figured out what it is - there are so many possible combinations.
Another problem is that mine don’t distribute according to the weight-painting - they are all over the place. Another thing the tutors don’t mention - it simply works for them!
The attached is a simple mockup of a much larger project I’m trying to complete.
Any assistance will be greatly appreciated rockmockup.blend (1.26 MB)
