Control area light brightness, spread, and samples.
- [Instructor] Let's learn about the attributes…of the Arnold native area light.…I'll select the light in the perspective view…and open up the Arnold render view.…Because normalize is off,…then the total amount of light…is affected by the size of the light.…Let's experiment, grab the scale tool,…and scale it up in the Y-axis in the perspective view.…And if we have a scale Y of about 200,…we can see that we're getting more illumination.…
Let's set that back down to 50.…We can increase the amount of light…using the traditional intensity value here,…that we can see in the channel box shape node.…That works in the ordinary linear scale…that you're familiar with from standard Maya lights,…but if you scroll down a little bit farther,…you'll see another one labeled exposure.…And that works in f-stops.…Each single integer added to the exposure value…doubles the amount of light emitted.…
Let's set the exposure to one.…Type in one and press enter.…And now we've effectively got…twice as much light in the rendering.…To get to the remaining controls for the light,…
