hi so I know there is a mixer tool but there is no mixer thing you can place and it mixes things for you I think it would be helpful to have that to add to your creations.
We have fans. And it's easy to turn a group of materials into virus, melt it, then throw it in a fan powered mixer with some soap. Plus, exactly how would a mixer material work?
Fan is a wall, and is sometimes difficult to work with since you need to remove it as a wall, not as a particle (different erase tool). A mixer element would probably switch the particles around it (adjustable range?) places.
