Glad they have option(s) to manage materials, and trust me......I have done the same in overlooking what later is seemingly so obvious.

Hi peerman,
Yes, Ted's reply solved the issue. I made the Render Time = 0 and that solved the problem!
I wished when i make it 'High Quality' preset, it automatically brings down the render time setting to 0 ...

In the meantime i by-passed the problem by using bucket rendering.
