bill, I was actually colouring mine grey so that I could see them, here are some non environment lit ones in white. It looks a bit like a blizzard has hit by the time you get to four bounces. I will do another post for the environment lit equivalents.

Now 2011. To be honest there isn't a lot of difference with the number of bounces, maybe around the window on the right of the house but it's not big. It does seem like radiosity and environment lighting in 2010 make a big difference but take a long time, infeasibly so for radiosity. Against this nothing 2011 makes a huge difference, radiosity (or indirect lighting as it's called) and environment lighting don't radically change things even the render times don't change by anything like the order of magnitude as they do in 2010. I'll go away and have a deeper look but the final score so far seems to be. Speed : without environment lighting or radiosity : 2010 wins by a healthy margin with environment lighting or radiosity 2011 wins by a massive margin (potentially the 5-7 times that was mentioned in the marketing blurb, in fact if you use radiosity in 2010 I'd say this was conservative) Look : obviously very subjective but, looking at billtheia's results as well as mine, 2011 does seem to wash out the details whereas 2010 gives more resolution.

Ok, had another look and now have got some non environment lit renders as comparison. These were a lot quicker than the environment lit ones. Interestingly, as I mentioned above, 2010 is quite a bit quicker with ambient and a light source. I also considered radiosity (in 2010 speak ) vs indirect lighting (in 2011 speak). This can be applied with and without environment lighting. Even without environment lighting 2010 with radiosity runs extremely slowly, but does make a noticeable difference. Indirect lighting without environment lighting in 2011 seems to make a minimal difference I have actually got six files so I will have to split this over two posts. First 2010:

I read the previous post on Renderworks with the same name as this one and started having a go myself. Looks like I missed the boat with that thread but I have got some renders if anyone is still interested. I liked billtheia's renders so they are pretty similar to his. I also had a go with indirect lighting to see what happened. The intensity of the environment lighting was set to 100% in 2010 and 200% in 2011, everything else was the same. Like bill I think 2011 renders much more quickly with environment lighting. Even more quickly if you turn Indirect lighting on. 2010 renders noticeably faster than 2011 if there is no environment lighting and you use Ambient lighting with a light source for the sun. I also found this somewhere else on this forum. Click the link and then at the bottom of the page click for a pdf about the change from 2010 to 2011. It actually makes a lot of sense. http://www.vectorworks-training.co.uk/Buy_Vectorworks/Renderworks.aspx It's by someone called Tamsin Slatter who seems to be pretty clued up. Matt
