Understand how to create decay in illumination using lights within 3ds Max. The video shows how standard lights do not fall off with distance by default. The video then shows how t use inverse square falloff to mimic the real world decay in illumination over distance. The video also shows how to create custom decay for special effects.
- [Narrator] In computer graphics,…we can actually define how our lights behave.…In the real world, lights fall off…with the square of the distance.…But in 3ds Max, we can actually change the way…that lights attenuate and decay over distance.…So here I have a simple scene…with a bunch of chairs…and a simple spotlight shining on them.…Now, if I want to, I can actually…affect the way that the light falls off.…
So if we scroll down to the…Intensity/Color/Attenuation tab,…you can see that I have a multiplier here,…which turns up or down the light.…I'm going to keep this at one.…And then we have two values here:…we have Decay and Attenuation.…Now, decay is the more naturalistic way…of going about this, so…right now we have no decay on the light.…As you can see, this light illuminates the last chair…equally to the first.…
In other words, the light is not…falling off with distance, which is…what it would do in the real world.…But we can change that.…So all we have to do is use this pull-down menu…to change it to either Inverse or Inverse Square.…
