Update for the dust from the main crack. References I used include the earthquake scenes from 2012 provided by Mr Douglas. I tried rendering the smoke out completely white and adding the colours in compositing as Mr Ron suggested, however it did not look very nice with a single colour. Hence I used a ramp for the colour based on the lifetime of each particle.
Below is a test comp with the single colour.
Managed to get some groups out from the geometry by deleting based on colour. This gave me the polygons that were created during the fracture in DOP, I could then emit particles from those surfaces, making it look like dust and debris emitted during cracking. However, this was not enough, as I realised that some of the cracks had been made with a Voronoi fracture in SOP and the inside group was no longer existent.
Currently rendering the final main dust cloud, and trying to render the dragon's aura again.
The high res rocks had to be ropped out again due to the rocks not having a rotation value after filing in from DOP. Mr Ron then showed me how to get back the rotation values, by doing a DOP import, importing the rocks as points, then ropping out those points. The rocks were then copied onto those points to enable them to rotate.
