I developed a scene to bring over to Maya, with the intent of creating about 60,000 buildings. I took a small section of it and exported OBJ to bring into Maya and render with Arnold. When I imported the file it created around 3000 shaders.  Since I have to convert all of these default Maya shaders to Arnold aiStandard shader I was wondering if there is a more optimized way to do this, I would think that I would not need more shaders than there are textures. I would also be interested in any other model or texture optimization recommendations. ... View more

I am trying to understand the Pompeii Example that I downloaded. If I open the file w/ out automatically generating the models I an reproduce the same results using the supplied traced footprints by selecting the lots, choosing the Pompeii.cga using the "Footprints" start rule and generating the models. I get similar successful results when selecting the Streetnetwork that comes w/ the file. However If I grow my own street network and apply the same rule and start rule and generate models I only get the courtyards w/ trees. You can see a comparison in the image below on the right you can see the streetnetwork that came with the file. On the left you can see the result I get when growing a streetnetwork myself. I have tried adjusting all the street patterns, many of the setting and all of the block settings. [ATTACH=CONFIG]23107[/ATTACH] The only consistent difference I have noticed between the streets I have grown versus what is supplied w/ the file is that the one that came w/ the file has more lots and they are highly varied in size, also many of the lots are much smaller. This leaves me w/ a few questions. 1. Is it the difference in lot size and variation that is causing the variation in building types? 2. If so, how do I get these variations? 3. Is that a way to inspect exiting street networks and see how it was produced? 4. Are there any docs describing this example in more detail? ... View more
