Sorry it took me so long to put these tutorials I promised I would put up ages ago, but life is busy as an Civil Engineer

. Also look for Indigo Network Rendering Tutorial. I know that the forum already has these threads under the sketchup section but these sheets are step by step documents so even the biggest rendering nooby should have a breeze learning the trade.
