With the wolves affecting the environment in fantastical ways, dynamics are an important element for our animation. This can be achieved with a combination of Maya dynamics and post effects, or just post composition effects alone.
Here are some initial render tests with Maya dynamics for the Shrine Environment. The soul is suspended in mid-air over the central shrine which reacts strongly to the wolves' presence.
Raw Maya Particles
The post effects gives a much needed boost to the basic dynamics, which will most likely be the best way to approach this process. It's still a little rough at the moment and will probably go through many more tests and variations, as elements such as lighting from the particles will need to affect the environment (current render is a single background plate).
