the picture on the right looks so real i can imagine someone actually walking around those bushes and in that walkway.. the one on the left looks worse than a fake magazine picture..

okay table listen to this: this all boils down to the bounce or the no bounce option.. depending on the scene- sometimes the 2 bounce option looks better than the 1.. with the 1 bounce you need to lighten of the shadows like i said.. with the 2 bounce you "reset" the exposure dialog to default.. for the most part the 2 bounces looks a little more UNNATURAL.. think about that.. to calculate light is hard enough- but to calculate it bouncing all over the place is near impossible.. but on the other hand- that extra bounce fills in the dark shadow areas and MAY look better.. so try the same render with the 2 bounces and the exposure set to "reset default"..

Interior rendering is a serious art.. if you look at a lot of professional interiors you will see lots of light bounces and relections and minipulation of light.. but i think just simple interiors are fine for just selling something like a house design.. here is an example of a simple interior without a lot of light manipulation and interior decorating and furniture..

table- but you need to know that even though i told you about being able to use 2 bounces- i will never do it.. it's just way too unnatural for me.. so the first way you did it with all the settings i gave you- that is the best way in my opinion..

" I think this looks more unrealistic as you said. http://img691.imageshack.us/img691/5770/3dview2.jpg I suppose i'm happy with the actual building in the previous render. I just need to use a brick texture that tiles better. What about grass? There must be some site i can download or buy grass that looks realistic? As well as plants. This for example: http://3dviz.com.au/images/adenbrook/Lakewood_Seville_Folio.jpg (the grass and plants in particular) Thanks for your help!

table- that 3Dviz render looks great- BUT you need to be a professional render artist to do that.. and they are rare.. of course any image that looks artistic rather than real will sell better.. but if YOU and I try to add light bounces and lighting effects it will look terrible.. that's why i just render with no bounces and no lighting effects- just full precision illumination and full soft shadows- that's it.. and that's the most real looking image you can get.. but if you want to play with artistic affects go ahead.. also there are many more artistic light setting in 3Ds Max than there is in revit.. same render engine though..

also table- if your computer is that slow and you don't want it to take so much time- make it a less MB size.. my computer renders that exact same scene in 25 min.. and if i buy the new i7 processor it will render in 10 min..

My computer at work here is getting old. It's only a dual core athlon 4200+ with 2GB ram. That last image took 10 hours to render. And i understand about the lighting - vray and 3dsmax probably come into play to get those sort of results. Can you make any comments on grass and plants? Where i can get them from? One that contains actual leafs of grass, rather than an image tiled across the surface that doesnt look realistic.

the kind of trees you are talking about is where the leaves are made with polygon lines.. accurender used those kind of trees.. and yes you can find many of those kind to use with mentalray.. and at first that's what i was thinking too- but now i'm used to the photo trees and i'm finally convinced that they really do work better.. they make a contrast to the building.. where the trees are an imaginary setting and the building is real.. the people who created this rendering program have figured all this out.. and in the end they are usually right..
