Emit smoke along local direction

Recommended Posts

Hi there,

Let's say I have two exhausts that emit smoke. The smoke is emitted from two spheres inside the exhausts, but they are animated so both exhausts and spheres change direction. How can I make the spheres emit the smoke always in a parallel direction to the exhausts?

There must be many many ways of doing this, but one is creating your v attribute in the parented sphere, and then bringing it into your source with an Object Merge set to Transform Into This Object. This transforms the v attribute, which then gets sourced into the sim. Otherwise this is just the basic billowy smoke shelf setup.
