I am using TG2 and can't locate the Simple Shape Shader input. Strange, but true.
			
			
			
				Indeed very strange. Do you want to put up a screenshot?
			
			
			
				Of what? I have looked at every Input option and can't locate Simple Shape Shaders.
 Where would I go and does the fact that "Dynamic Link Library not available" appears when I start the program?
			
			
			
				It's both under color shaders and displacement shaders.
			
			
			
				I have 9 under color and 12 under displacement, none say Shape Shader. Is it a subset of them or not?
			
			
			
				Are you positive that when in Terrain tab.. if using fractal terrain....with fractal terrain control box open...mask by shader...create a new shader under Displacement...simple shape shader 
The simple shape is used as a mask or to invert a mask. It is not an object like rock, plane, sphere, etc that you can use independently.
You can mask a surface layer to fine tune position and many other uses.
