I have a heart object:
I want to add crystals growing out of it (see image below for example of what I want)
So far, I've been manually adding crystal objects one by one, but I want to also be able to create a "skin" of crystal crust on certain faces, so that I can easily cover swathes of the heart in a fine scattering of crystals.
Should I use a particle system? Is there some way I can "spraypaint" crystal dust (not just texture, but actual crystal geometry) onto the model?
The heart will be animated, if it matters.
