Geekatplay has a tutorial on 3D ecosystems, which is what you're after. Basically, the technique consists in applying an ecosystem to an object and applying a noise function in the slider "offset from surface" (the noise must be multiplied and biased, otherwise it's too small to be noticeable). It's not complicated and the manual doesn't refer it probably because this is acomplished just using the normal tools available in the material and function editors.

This requires you to work in the function editor. If your vue version can't do it, you probably won't be able to create this kind of ecosystem.
