Hi! I have been trying to learn Houdini's pyro system, but am fairly new to node based workflows so it is a slow going process. One thing I have found absolutely nothing about online is how to make a smaller more contained explosion, like that of a hand grenade or a breach charge for a door. All the tutorials I have seen online are for large scale explosions that result in a huge mushroom cloud look. I have tried working with those and seeing how to change them to more of what I want, but don't even have an idea where to start. Can anyone give some insight on what I should do? The other thing I don't know how to do regarding the breach charge is a directional explosion, where it is exploding sideways into a wall. (I have a way to destroy the geometry of the wall, all I need to know how to do is make the explosion) Thanks for any help!

something similar to this, but I am going to have mine explode on concrete, so less of the dust and more just smoke and fire.
