Understanding Lights in Maya - Part 1by Aziz Khan, Afghanistan
5 - Now hit render without any light setup, and you should see something like this...
Ambient Light
6 - It's time to drop light in the scene...
7 - Once the light created in the scene, Move it up on the top of your object, and then hit CTRL+A to bring Attributes Editor or in the other words to brings it's parameters
Color = this is the color of your light you could change the color of your light to any color you like,
Intensity = this controls the amount of your light, more values the brighter result and lower value the darker result,
Illuminates By Default = with this option you could ON and OFF the light,
Ambient Shade = I don't think you will need to play with it, the default value is 4.50 keep as it is, if you want to play please feel free, by increasing the value you will have a bit soft and darker light,
Shadows = its pretty self explanatory, if you change the color you will have the same shadow color you gave in the color chooser,
Use Raytrace Shadows = if you check this out your object will start casting shadows and this works nice with Mental ray,
Shadow Radius = this will soften the edges of your shadows,
Shadow rays and Ray Depth Limit = works almost together these could help you to achieve smoother shadows result
8 -
In the render settings do the same settings as shown in the below image
Global Illumination is dealing with indirect illumination, specially works fine with photons, we will talk about photons in the Part 3 of these tutorials.
9 - Last but not the least still in the render settings check (Final Gathering) this option will help us to illuminate more and to get overall smoother result of our final output.
