Achiving Sand like particles.

Unity Engine
1

So I’ve been messing with particles for a while I can’t say I’m a pro but I know some stuff. I know that collisions between particles are not possible in unity how ever I’ve been wondering would it be possible to get an effect like this below. When particles collide with the wall they stick and build on top of eachother especially between 0:37 and 0:44 it’s really visible. I’ve been wondering would this effect be possible in unity. For example make a mud but you know realistic.

I don’t see much thickness being built up here, it almost looks just like a color stencil they’re painting on.

You might be able to get somewhere combining a depth shader effect with some kind of decal…

Maybe you could have a wall that was made of a mesh of verts and your particles would impinge on them and “lift” the verts out from the normal of the original wall. It would work to an extent, as long as you could limit how much they were going to spackle on.
