Looks really cool! Aren't droplets a bit too high?

In what field are you working btw?

Thank you! I think you're right about droplets. Their height was tuned for other shot, which was framed from bigger distance and taller droplets looked better in it. I probably should've readjust the height for this shot, but... oh well. Maybe next time :]

hehe, I feel you, I won't blame you for that. I'd probably do the same... I really like this car!

Those vintage cars, some of them are so lovely :]

I got comments that the raindrops aren't very convincing and they looks more like icing rather than water droplets. I think it's mostly due to the lack of caustics. I tried to enable caustics (in the material, not the global solver) and indeed in some places raindrops started to look much better, but in the other places they looks just completely wrong, like stain of dirt :/

How did you create them?

I think the shape of the raindrop is really important, especially when using caustics.

Hmm, interesting point. Raindrops on the non refractive objects are created by duplicating the mesh and assigning "water" material with displacement, so yeah, due to the very small size of the droplets, their shape probably is far from perfect. I'll try to scatter some mesh droplets and see if that works better.

So i did some testing with raindrops made from mesh instead of displacement. Droplets was made bigger intentionally, to better see what's going on. Even without caustics it can be seen some improvement, probably that means that displacement couldn't provide enough subdivision. When caustics are turned on (again, only in material, not in caustics solver), raindrops starts to look much better at glancing angles, but i think there's too much shadowing on the droplets on front facing angles. And oh... look at the droplets on the chrome! What the...? Looks like ink, not a water :/

I figured out how to fix the chrome issue. It looks like caustics don't work on layered materials. I've changed chrome to simple Corona material and caustics have worked.

Testing procedural galvanized steel material. I might eventualy replace procedural map with bitmap, if manage to find decent quality one.
Very early wip.

Its surprising how many times ive needed procedural galv steel and how many times ive never done a thing about it.

I think Corona material library has some galvanized steel materials. Doesn't it?
