Understanding Lights in Maya - Part 3by Aziz Khan, Afghanistan
Hi Guys and welcome to part 3 of (Understanding Lights In Maya), in this tutorial we will understand the Area Light and Volume Light. In previous parts we already covered Ambient, Directional, Spot and Point Light. Please read the Part 1 here and Part 2 Here. Ok let's started by creating a Area light in the scene.
1 - Select the Light, open Attributes editor, now activated Ray Trace Shadows
2 - Hit render and
you should have something like in the image below, as you can see the shadows are too grainy and we will fix this issue next by increasing (Shadow Ray) and the (Ray Depth Limit)
3 -
Now in the light attributes increase (Shadow Ray) and the (Ray Depth Limit) according to your need, and then open (Render Settings) by going to (Window>>Rendering Editors>>Render Settings), Expand Raytracing tab and crank up the values as you see in the image
4 -
Select the light and then go to its attributes once again, and now expand the (Mental ray) tab, make sure your rendering engine set to Mental Ray and Global illumination is ON in the Render Settings
Now you should see couple of different option like (Use Light Shape) and (Emit Photons)
Use Light Shape = you could change the shape of your light to (Disk), (Sphere), (Cylinder) and the (User), so go with any shape you like,
Emit Photons = Photons are basically small point which cause indirect illumination in the scene and keep bouncing from one object to another until they die
