I have a particle system placed below the floor plane. How do I fix this:
There’s no technical fix, just tweaks to make it look better.
Can start them smaller, then grow as they rise, so there’s never any clipping. Can lay them flat, so they can’t clip (but they will still clip any bumps you have.) Can change it to have many more, smaller particles. Can add a 2nd system on the ground, to cover up the clipping. Or, the most common solution, can adjust it as best you can (maybe make them a little more grey) and decide it’s good enough (look at tripleA tittles – there’s are many, many “small” imperfections, but it’s fine.)
