Sorry, first post.
Trying houdiny fx a 2 days and creating an explosion by tutorial.
In one step he tab shop menu and fireball shader created by default, but i haven`t it and don`t know how to create. Can you help me please?

Hi!
Now all the shaders have been moved from the “shop” menu to the “mat” menu. If you used the shelf tool for creating the explosion, here you should find the fireball shader created by default.
