Reduce the reflectivity and tone down the bump mapping.  They also will resolve themselves if you render at higher quality settings...

Try a region render at high or best quality first to see if it fixes the issue.  Its generally to do with the number of bounces for reflectivity in your render settings.  If the surface is bumpy it can take extra effort...

I'm rendering at High at 600 DPI in office ower night so will se the result tomorrow ...

 

Is there some good GUIDE hwo to render in revit 2010 ? I would love to make photorealistic images

at work:

Intel Quad Core 4x 2,3 GHz

4 GB Ram

 

but the render goes too slow compare to 3ds Max where fotorealistic render is about 30 minutes or 1 hour max ... Sad

 

Any help there from Autodesk or other programs/options ?

The result looks good at High, but it rendered whole night.

I saw Artlantis released addon for Revit to Save files for him and than render them in Artlantis ... will it be faster ? (how much faster?)

 

Any experience someone with Artlantis rendering ?

Interior renderings in Revit are somewhat slow as generally for interior renderings high detail is required and also artificial light sources which slow things right down.

The difference between rendering an identical image in Revit on a quad core pc to Max would be neglible.  They use an identical rendering engine.  Max is streamlined a little better so might finish about 5% faster.

You can achieve results quicker in max because you have more control over the rendering settings and can "fake it" if you know what you're doing.  It can also take advantage of more processors or render farms using Backburner...

Zachary Kron posted some interesting figures on what materials take the longest to render so you may wish to check out his blog "buildz".  I've managed to produce some very realistic images in Revit, but generally they've taken upwards of 48 hours of processing to complete.  It's also a good idea to just render the screen resolution rather than a printer resolution...  This gives faster results and most screen resolutions these days are good enough for a decent size print if needed.

 

I haven't used Artlantis, but Vray seems to be the architectural render of choice for most these days...

 

HTH.

But the V-ray can be used only in Max, or is there any way to use it in Revit?

I need high resolution images for A3 printed images on photo pape, so I need really high resolution because its mostly interier ...
