The exploding stick of dynamite below is an example of an Omni Emitter. Used to create the burning sparks of the fuse and the ultimate explosion. It was certainly a colourful tutorial to complete and amusing in its cartoon sense. There was an enormous difference in rendering time when the dynamics were rendered using the Hardware Render Buffer. Its only for graphical purposes but its really very quick.
The directional emitter can be seen working its magic in the video below. Rather than the more gaseous or sparkly forms of particles this time they take on a far more solid form. I decided to go with a more cartoon liquid, I wasn't a big fan of the brown, so I decided green slime was a better bet. I think I needed to further adjust the threshold for a more 'liquid' run-off. But for cartoon slime the stodgy mess in the video below will do for now.
