View Full Version : fireplace lighting

hey there maya lighting masters, i have a question for you. In the movie Shrek, where he's eating dinner and donkey is outside, the lighting with the fireplace and the shadows jumping around, how can a person imitate that?.
I have only 4 light sources in my scene, and they are a fireplace, 2 torches, and candle.
Thank you for your help .....

i would guess the fire is a lightsource, and the light flickers are due to the fire flickers.... they programmed their own fire sims, so you'd have to do that to simulate the fire animations.

Hi there, I used this expression for the candles in Jonah and I'm actually working on a fireplace flicker for a new show right now, so I'll share it with you....
fireLightShape.intensity = 1 + noise(frame*.2) * .3
The first part is the name of the light's shape node and the intensity attribute that we are going to affect
1 is the intensity of that light that looks good in your scene (mine right now is .68 for my scene)
.2 is the speed of the flicker or "noise"
.3 is the amount higher or lower you want to affect your intensity...in this case the light intensity would flicker between .7 and 1.3
You can also modify this expression for moving the light slightly or changing the color for more detailed "fire light flicker"
Hope that helps and support your fellow CG artist by seeing Jonah!! :D

Thanks, Steve. If it does well it might head over seas...but I can't really say for sure because we just don't know what's going to happen. We're all pretty anxious to see this weekend. Really anxious. :argh:
