I am playing around with particle systems, and have been experimenting with this tutorial: https://www.youtube.com/watch?v=2bv973aqx-w
The system emitted particles from an icosphere, but the particle emitted is based on another object in the space. I'm basically trying to make it look nice. I think that when particles are next to each other, you cannot distinguish the shape, which I think doesn't look very good (Figure 1). When the particle system is selected, the objects all have outlines, which I think looks cool (Figure 2).
Is it possible to add an outline to a shape (i.e. every object in this particle system is based on an emission cube I have) which will then appear in the particle system. The main solution I've found online to getting object outlines is 'freestyle', which I don't think will work here as it is applied after, and therefore the cube generated in the particle system wouldn't pick it up.
Any solutions/workarounds welcome!
