My office is thinking about purchasing 3d max for rendering. I've been trying to render in revit 2009 and it's taking multiple days (a ridiculous amount of time) for one flat view. My computer is a Dell Optiplex 755 Quadcore with 3.25GB RAM. I have Windows XP installed but am thinking about switching to 64bit Windows... would that improve my performance? I'm wondering if anyone has suggestions for programs, versions, types, etc. to get very high quality and fast renderings. Also, what type of computer should I have to accomplish this in an efficient amount of time (a few hours max)... ie) ram, video card, memory, etc? Is it better to have a computer dedicated to just rendering? This will be used for mostly interior renderings and I want the artificial lights on (I think that's what is slowing my file down at the moment). Any suggestions? I need to know the BEST way to get a really high quality image. I'm also interested in creating rendered walk-thrus but at the rate my flat images are rendering I haven't attempted it yet. I imagine it would take an insane amount of time. Can I do this in 3d max as well? Lastly (if it's the best way to do it) I need some tips on importing from revit into 3d max. File type? Can you retain assigned materials or is it better to put the materials into 3d max?

Hi there. I am doing the same research for my company now and I have already couple of answers to your questions. First of all and I know this well. To faster revit renderings you need 64-bit, 8Gb Ram for sure. Then it comes to Processor you can use Intel (R) Core (TM) 2 Duo or Quad. More capacity even better. Hard Drive don't go less 350 GB. Better Over 500. keep available about 30% to speed up rendering process. Video card also should be good. INVADA for example. We swiched to these type of machines after using Revit in the company. It's all DEM expansive. I am shopping right now for new loptop. All that build-ins about 3500-4000 baks. All that makes revit render much faster, but not so fast I would want to. Then i decided to buy Max for company to export revit models through FBX to revit. As I heard you can put the same path for material library for Revit and max and you don't need to re-apply anything. Max renders 50% - 85% faster same view for the same revit model then revit. % depence of quality. Also you can add animation (people, cars etc) when rendering revit model in Max. Forget about rendering Walkthrough in Revit. I never could. Takes VERY long. I quit. In max probably better.

When you guys convert to max be prepared to do some training in Max, the Revit FBX export is not flawless but it does retain materials as well as lighting data, sun and location settings. I do find myself applying different shaders in Max quite often just so I can get a higer quality render. There are also different things to learn such as ambient occlussion and motion blur if you are looking for realistic animations. Your optiplex will be fine for you to start learning, the great thing about Max and Mental Ray is you can do distributed rendering. This is when you network all the processors from computers on your network to render a single image. I can have 64 processors at once rendering my image. Which means I can render animations at a much higher quality and produce much more than on a single PC

Thanks a lot to you again. I've heard about that ability to use several processors and using network. Using Maya you also can do this, but not Revit yet. I have Indian girl in the company she is the expert in Maya. But the strategy is to get Max first to speed up rendering process of the projects in the production. Then Maya. Company doesn't want to pay to send me for Max trining. Everybody doing not well now moneywise. So, I guess I have to learn it myself like I did Revit years ago. Wish I had somebody to tech me how i am teching people Revit now in the company. I am little lasy. Anyway after bying Max I will have more questions to you guys. Thanks a lot.
