			of the material you are currently editing.
			Material specifications defined via Realistic Rendering 
			are shared with other Version 5 products. 
			 
 Modify the 
			Lighting parameters: Ambient, Diffuse,
			Specular, Roughness, Transparency,
			Refraction and Reflectivity. You can either use 
			the slider or enter the desired value directly in the box.
 
By default, the Ambient, Diffuse,
			Specular and Transparency colors are set to the 
			basic color.  
			 
 
			
You can, however, click

When satisfied, click OK, and the color is 
			applied to the shape in the preview.
 
Set the 
			other material parameters.
 
Click OK to validate the material lighting 
			definition. The material icon reflects the material as defined.
