Just a quick update of the progress of the animation. Early stages of post-production, adjusting levels and colours, sorting out all render layers and placing files in correct order.
This scene proved itself to be really problematic and took many hours (count in days) to figure out the issues. From colliders to constraits I worked the way out of a problem and because it took a lot of time I am sharing a selection of fails (unfortunately some of the most dramatic ones didn't get saved).
And the final version where hair of both the Mushroom and the Plant twin works fine, doesn't have problems with scale or geometry forming into crazy shapes.
