You are never going to get a photo-realistic rendering out of Revit and its default rendering engine, Accurender. The power of the software isn't its rendering capabilities, its in its database capabilities. Accurender is just a bonus for doing "ok" renderings. However you can use third party software like Autodesk Viz to render models created in Revit - it will take some research, but people do it all the time.

Hey jmiller,
There are alot of tricks you can use but bear in mind that many lives are spent trying to capture reality. While hjacobs is right that Accurender is more than a little behind Viz, Max and other leading rendering programs, I think it still has potential.
In regards to your image, could you post the raytracing settings you used to get that image? Its a great start, and good on you for being so willing to ask for help - I hope this does just that!
Some points:
Try and hide that horizon line. So seldom do you see such a straight line in photos, experiment with background photos and trees placed back from the building.
Those clouds seem a little grey, again you could try making them white or using a background image. And the sky could be a little less green...
Download some cars from this site, they render out real nice - and its a good idea to balance compositions with background and foreground information. At the moment your whole picture seems to exist at a similiar distance from teh camera.
You could try having some massive trees on the left (off camera, out of sight) and have their shadows casting over that massive area of pavement.
Email me with more questions if you like, you're on the way!

after you have finished the rendering, use the adjust image tool to change the brightness and contrast. then take it in to photoshop and do what has been suggested. put in a good background that blends well with your biew, then make some layer changes. for example, most of the time, you can apply and overlay layer to your image and that tends to make things look quite a bit better. but like its been said, unfortunately revits rendering engine is not quite as powerful as the others that are available.

yeh i was wondering if exporting a revit file to dwg and then taking it to viz is possible without having all polylines. If anyone has had experience in using studio max or viz render with revit could you plz message me or post some tips. Due to the fact that they change to poly lines there are so many faces in the model rather than whole slabs or walls ect. Is there a way to stop the model from changing to all polylines

I'm not quite sure what happened there with your plines. I use file>export>dwg. I'm in a 3d view when doing this. From this point I open up Max>File>File Link Manager>Import File and it opens up beautifully. No plines, all modeling. I use a very basic max file with lighting already in place and import my dwg file into that. This way I have my shadows and views already set up for the next one.
Personally, I think accurender is horrible. I don't hold out much hope for it. I wish Autodesk would include Viz with Revit like they do with ADT. I'm sure that's some type of internal business conflict though.

Accurender on its own can actually turn out some pretty impressive stuff, especially for interiors, and it's a lot faster than viz. The problem here is the version of accurender they included is really stripped down and makes it difficult to do all the little "tweaks" that are needed to get to that level.

I have found that one can achieve a high since of photo realism if they spend the time to find the best maps. I get almost all mine online. I believe Revit has the lighting capabilities to be good enough, as well as the ability to create great shadows. If you combine the lighting and shadows with the proper maps, then you will see a huge improvement in your renderings.

can someone just clarify something for me about revit rendering? by the way, i have attached the worlds crappiest renderings to this message so u can see where i am at, because i want to make them look a lot better but dont know how... my question is...when u render in revit (just using the rendering tab) you dont get an option of what type of rendering engine u want, right? when i do it, i dont see an option for rendering engines, so i assume it is using some sort of default rendering engine. i see ppl posting info on accurender, mental ray, etc. what kind of rendering engine do i have and what kind do i want?

Revit 2008 use the Accurender engine and Revit 2009 use "Mental Ray" engine, you can't choose "of what type of rendering engine u want" What you can do if you aren't satisfy with your renders in Revit is "insert" your model in Max and use the "V-Ray" to create your renders....

V-Ray is another rendering engine apart from the two Typhoon listed. In 3D Studio Max V-Ray gets installed as a "plugin-like" feature. Once installed you have 3D Studio's native rendering engine AND V-Ray. You basically get rendering engine options (e.g. mental ray, v-ray, etc) at that point to satisfy certain rendering needs. Google V-Ray for Max and you'll find loads of information.

Charlie, I just released a video series focusing on nothing but presentation techniques for revit. Within that video series I have an hour long segment about using Revit to 3DS Max and rendering with V-Ray.
VRay is definitely an excellent render engine with some insanely realistic results. That being said, you CAN get Revit renderings to look very similar to VRay renderings. I show some of tose techniques as well. There are some examples on the site listed below.

i have attended many trainings in revit, but still i have a doubt regarding floor finishing with tiles.
i would like to know, how i can put ceramic tiles in various sizes in a room, may be 2-3 different sizes of tiles comes together. or i may need to cut some patterns on the floor that is filled with marbles, like water jet cut designs.
i know how to add material but i am confused to make it tiles and other designs.
