Of all the work I did on MotoGP, I think I am most proud of the wet weather effects. Official Xbox Magazine were kind enough to call it "The World's Best Rain Effect (TM)".
What can I say. I grew up in England, and now live in Seattle. I know rain :-)
I think there are two main reasons why this rain looked good:
Rain consists of drops of water falling from the sky, right? So we should probably start by using a particle system to draw these raindrops. But when we looked at photos, falling rain was rarely even visible!
Come to think of it, I often glance out the window here at work and can't tell whether it is raining. "It's certainly overcast and misty", I find myself wondering, "but is this rain or just lots of vapor in the atmosphere?" I can only directly see the falling rain if a headlamp or streetlight is shining on it, so the best way to tell is often to look for a puddle and see if there are any splashes.
Using our reference materials, we concluded that rain affects the appearance of MotoGP races in several ways:
Note how falling rain is not part of this list, so we never actually bothered to implement that.
As for the things we did implement, there were (as always) some constraints:
Stay tuned for more...
Uhh, I am looking forward to this! Especially the water spray and wakes in the water, but also the lightning flashes.
Interesting read. I live in Seattle as well and have been to the UK many times (my wife is from Coventry).
I like the fact that you never actually implemented "falling rain". This seems like a good example that can be applied elsewhere in design and programming. What can be seen/heard of the cause/effect relationship with that you are trying to emulate and simply just create the effects vs. a direct simulation of the cause. Ugg, or something like that.
I'm upset that I can't find a video of these rain effects anywhere :(
Dang it Javad, you're right! Who knew there were things that weren't even on Youtube?
I found plenty of videos of people playing MotoGP in sunny weather, but only two in the rain, one of which was so badly compressed you can't see what is going on, and the other looked like it was captured on the PC version with all the graphical details turned off.
