A (sci fi) military scene in bad weather. This time I rendered a "clean" scene (no atmospherics) plus a bunch of fog-, rain- and splash passes. Besides from having more control in the end it was way faster to render this way than all at once. The pure scene is rendered with the path tracer, and the atmospheric stuff with the legacy renderer.
For the steamy area directly over the vehicles' surface I did some more postwork. I rendered larger instance versions of the splash populations (which are actually again modified grass clumps), blurred it and erased unwanted parts in Photoshop. I haven't found a way to use a cloud layer for example for this.
