Rendering Survey

[tc3dcad60731]

I was wondering what clarity y'all use for rendering your revit views?

72dpi took about 25 minutes and looks bad
150dpi took about 50 minutes and looks pretty good
300dpi took about 3 hours and looks real good

Not sure that moving from "pretty" to "real" good is worth two more hours.

300 min. Often higher.

I never understand how other peoples renderings take so long. I never use anything less than 300dpi, and that normally only takes 5-10 mins max.

I tend to use 600-700dpi, even up to 1000dpi for top presentaion work.

The 600-700 renders usually take 20-30 mins max, the 1000dpi probably an hour or more (normally done over night...)

Add lighting into the equation, especially a lot of them, then it can really up rendering times.

300 dpi here.

I also take an inordinate length of time for 300 dpi.

To combat this I do plenty of 150dpi renderings to make sure it is ok and then render overnight. My 150 dpi renderings usually take less than 10 minutes.

My tendency of late is to move away from accurender and just use the revit rendering engine with sketch up imports for entourage.

Well it hung up my everyday machine which is a power horse so I used my presentation laptop to complete the rendering. That may explain some of the time BUT.....

2.8 P4
2GB of ram
128MB ATI X600
Win XP
5400rpm of the HD though!

I rarely ever up the resolution past 150 DPI... Normally i would want a much higher resolution so i could take the image and make it larger after the fact... But i just make the image larger using the Crop Region Image Size settings, and then render at 150.

We typically dont go for photorealistic at all, but we have in the past, and then i used the 300 DPI. I try not to use the procedural trees though, ive found they immensely slow down the renderings...

Recently following Max's footprints... I cleared all my rendering profiles. created new ones.. went from crashing to 5-10 minutes for 300dpi... that's with landscaping which appears to be a drain for rendering.

Other tricks to be learned... we recently posted copies of our renderings.

I am in process of helping a client finish a retail space with 30"x 45" photographic images to designate areas in a food store. We are using a print company that does solvent printing on large bed image plotters. For photographic reproductions, their recommended minimum resolution is 100 DPI, so we used only 150 DPI !!! and the images were perfect.

What appeared to be the best route, was a larger resolution image on a smaller format, then simply use photoshop to change the image size and resolution.

Normally, I use 300 DPI on my renders, printing to a small HP inkjet and printing 8 1/2 x 11 prints on color glossy paper. If a moire is introduced in the image, I will kick up the resolution to eliminate that effect, but usually only then.

As far as time, my renders usually run 10 minutes or so, unless I'm running a radiosity solution. Be sure cull surfaces not seen is selected to help eliminate time, and you can turn off (RA8 ) elements not seen by selection to also speed up the process....

For those interested, Maxwell has increased the speed of its render engine. For a really clean image, you'll need to run over night, but two hours yields great images now. - Attached are a couple of two hour renders (800x600) in maxwell..(Revit modeled linked into Max with Maxwell render engine.)

Wow - I have learned alot from all of you on what you do with rendering.

#1 - Culling was not taken care of
#2 - other RAC08 images were still on apparently

Will re-run the rendering later today and see how long that takes now. Again, many thanks one and all!

If you can add your trees in photoshop it will help alot. just a building prior to adding entourage only takes 30 min or so at 300. once you add some trees, plants and cars, thats where your into many hours of rendering.

I voted for 300dpi, but honestly it depends on the actual print size and type of the renderer.


300 dpi is not necessarily a good thing to go for, if your rendering is 24"x36"....somewhere between 133 to 150 is ok....when the render size is smaller, I usually don't do anything less than 300, because then I can print it to a larger size... It's easy to decrese the size/dpi, but it doesn't always look good, or even feasible, to increase the size /dpi...

remember that 300 dpi doesn't mean anything unless an actual print size gets included in the equation...

1"x2" @ 300 dpi is 300x600 pixels, where a 10"x20" @150dpi of the same image is 1500x3000 pixels.

Take care,

Luigi

I don't care about DPI. 5000px wide for final renders with AccuRender in Revit. Quality set to Draft/Draft for exteriors.
