Notes 04: Light Shaders

1: Create a Point Light palce it insde the lamp
increase the intensity, set decay to linear
switch on the raytrace shadows
















2: under the point light attribute, under mental ray go to custom shaders and then select
the light shader and apply physical light
( now none of the point light attribute changes affect the light, only the physical sky changes it)

The colour attribute here is incharge of the intensity and by default the values of RGB are set to 1000
Threashold of light tightnes the area of light around the light
















3: change the spot light to an area light and use the shape of a sphere, scale down to remove the graininess we can change the samples
















4: Change the shader of the lamp
