3D AutoCAD Render Tip: Quick settings with great results

[StykFacE]

For use of AutoCAD 2008 and up.

I thought I might as well add a little tip to the forum. Its been awhile and through the little knowledge I actually do have in rendering, I'd like to share what I feel is a great tip for making a render look good by changing a few simple settings.

1st, when you have your scene set up, type RPREF at the Command Line to bring up the Advanced Render Settings. Set the preset to Presentation. Look at the first image to see a render at these default settings:






It looks good, but we can definitely do better. Now simply set the Final Gather setting to On. See the image for the better results:






To really add a more realistic feel to your render, then don't forget Indirect Illumination lighting techniques by using the Global Illumination setting. (click the lightbulb to activate this parameter) This allows light to really bounce off objects in a realistic way to create a nice image. See image for the results:






These are some very important quick settings that I like to use. I wanted to simply show the differences in improvements in these very easy change of parameters in the Advance Render Settings dialog box. Hope this helps some of you out.

Very nicely done StyKman.

Thanks for this. I want to start trying to understand the render settings as they're a world away from my drafting skills.

I like the pics; Turner prize material IMHO... you could be £50k up soon!

Did anyone see the 'installation' in the Turbine Hall at Tate Modern; can't remember the artist's name but she was famous for injecting stuff with plastic then cutting the plastic out so she had a "sculpture" of the inside of really exciting stuff like, for e.g. a radiator...

She FILLED the Turbine Hall (which is massive) with thousands of... (wait for it)... plastic moulds of the inside of ... (wait for it)... archive boxes.... it was amazing, it was almost as if it was a real warehouse full of archive boxes... hmmmm...

I really do reckon we should enter something - what do you reckon lads? We could all draw one solid primitive then email off the dwg for 3D printing, assemble the lot into a big room and enter it as art? CADTUTOR's contribution to global culture?

i know this thread is quite old, but i have tried these tips and it took me almost 45 minutes to render my scene.

What are your computer specs?

Processor: Intel(R) Core(TM)2 Duo CPU @ 2.40GHz
Memory : 1024 MB RAM
Display : NVIDIA GeForce 8500 GT

45 Minutes sounds about right for that hardware setup. Your Processor isn't bad, but 1GB a RAM just isn't going to cut it. Nor is that gaming card.

Quad Core processor, with 8GB of RAM or more, and a workstation level graphics card will be your best bet. Cad64 does know quite a bit about 3D rendering and I would think he would agree.

id really wish have to a pc with that kind of specs. But for now i'll just have to settle for whats served. im saving for that though.

Well, rendering still takes time with a stout workstation. Best thing to do is pick up a few older, cheap (even free) computers and keep those on a network for rendering purposes only.

ok. Thanks for the advice sir.
