I've just rendered this scene for the first time, and you can't ask about the timeline because, like foreplay, it's always longer than you expect =D.
This is the raw, pre-post-processing version - think of it like catching D.va before her morning coffee.
There's hidden potential I'll use to make it even spicier. Did this render to see if anything else needed spicing up, and yep, D.va's looking chilly without something hot and steamy and well... started making a heater.
Now, don't bully me for trying to be cinematic and immersive.
Still need to build the fluid pump to also fill the scene.
The idea for the heater came to me when I recalled the dust particles glowing in warm light, a cozy effect some game developers used in games like Dead Space 3.
