Revit LT finally released

image

So today Autodesk finally announced the release of Revit LT. More details can be found here….

http://usa.autodesk.com/revitlt/

Autodesk Revit LT is built on the Revit platform for BIM and allows users to create designs efficiently with 3D, real-world building objects to produce reliable, coordinated documentation faster.  Revit-based applications help deliver better coordination and quality, and can contribute to higher profitability for architects, design professionals and the rest of the building team. Some of the benefits of Revit LT include:

  • Work more efficiently with a single, coordinated model that allows users to concurrently design and document building projects. Autodesk Revit LT automatically manages iterative changes to building models throughout the documentation process. As a result, a consistent representation of the building is maintained, helping to improve drawing coordination and reducing errors.
  • Design and visualize in 3D. Revit LT allows users to see their designs virtually, improving their understanding of the building and its spaces, and helping them communicate design ideas to clients more clearly and effectively.
  • Create photorealistic renderings in the cloud. Users who purchase Autodesk Subscription with Revit LT can render in the cloud directly from the Revit LT interface, enabling them to produce compelling, photorealistic visualizations without tying up their desktop
  • Exchange designs in the DWG or RVT file formats. Produce designs in the DWG file format, and experience fluid file exchange with project team members using other Autodesk Revit software applications.

What I think is more important, is to actually understand what you are & what you aren’t getting by purchasing the LT product. This is explained in more detail on the feature comparison page. You should review this carefully.

Certainly if you are a small firm looking into the delve into the the large pit of BIM, it certainly worth reviewing Revit LT. But you must be aware of some of the limitations of the product, particularly the lack of collaborative working functionality.That’s not to say you cannot link in Revit Structure or MEP files, as you certainly can. If you are a small firm developing Revit content or working on small projects where you don’t need to necessarily collaborate between users working on the same dataset, then Revit LT is a good start point.

Tutorial: How to set up Distributed Rendering in Vray for Sketchup

What is Distributed Rendering (DR) Spawner?

Distributed Rendering is the capability to render a single image across multiple computers. This has the possibility of utilizing multiple computers which can greatly increase rendering speed. VRay can use up to ten computers with just one license.

Tutorial: How to set up the DR Spawner in Vray for Sketchup by Edgar Navas Via Sketchup Vray Resources Blog

Firs of all, you have to connect yours PCs in a LAN (Local Area Network) and know each IP address. By default, Windows OS come with DHCP activated, which is the hub that assigns the IP addresses of each pc.
In my case, for practical reason I made my LAN with static IPs. The default IP address is 192.168.xx.xx. I use another because I manually assign IP address to a specific PC. I use 172.16.25.xx

Ok, going back to IPs issue, to know what is the IP address of each PC, in the windows star menu, choose run and then CMD. A window like this should appear.

1

Inside the DOS windows, you have to type ipconfig and then key enter o intro and the screen will look like this.

2



In my case, my IP address is 172.16.25.7 this can be done in each PC that you want to connect whit DR Spawner.

Second an important thing to know, probably you have installed V-ray without Distributed Rendering Spawner, again run the installer an choose only the DR Spawner option.

3

Once the DR Spawner is installed in each PC you have to run, it. It can  be accessed using Windows start->Programs->V-ray for Sketchup->Distributed Rendering Spawner. When you run the DR Spawner a window like this should appear.

4

Don`t close that window.

The third important thing to know is the Window Firewall. You  need to set up permissions to the Windows Firewall.


5

Ok, almost done, to make sure that the Master is connecting to other PCs run CMD again and type (in my LAN is) ping 172.16.25.xx -t where xx is the number or numbers assign to each PCs

6

Now the LAN is ready to make a Distributed render

In V-ray Options->System check box ON and then click to the button with 3 points

7

Here is for config the hosts (slaves) add server write the IP address and OK

8

Enter all hosts or servers, click on the button resolve servers and check the IP addresses that we have entered.

9

Check the box for each server

9b

And done, Distributed Rendering Spawner it's configured.

Distributed Rendering Spawner Off

9c

Distributed Rendering Spawner On. Starting

9d

Distributed Rendering Spawner On. Processing.

9e

Distributed Rendering Spawner On. Almost finished

Rendering Tip for Interior Scenes using Mental Ray and 3dsmax

A great detailed tutorial on rendering tip for interior scene by Jeff Patton on his blog:

I want to share a few tips for rendering architectural interior scenes with mental ray, using the mr Physical Sky and portal lights.  These are some fairly specific tips that will hopefully allow you to achieve a smooth indirect illumination solution as well as control the intensity of the sun and other contributing lights.

I’m not going to start from the absolute beginning here.   To get the most from these tips you should already be familiar with the basic fundamentals like how to add a daylight system to your scene, enable the photon target option on the mrSun, enable global illumination, etc..  If you’re not, then you’ll need to spend some “quality time” with the 3ds Max documentation/tutorials.  With that out of the way, I’ll dive right in.

I’m going to use the Evermotion bathroom scene that shipped with 3ds Max a version or two back.  At the end of this article I’ll post a link to my completed .max file for further reference.

I started by stripping any lights from the scene, hiding the window glass, and applying a single material to everything.  That’s primarily so I can focus on the lighting tips for this article.

I then created a daylight system and let it assign the mr Physical Sky to the scene environment and assign the mr Photographic Exposure control.

I then edited the daylight system to remove the mr skylight.  It’s not needed since I’m going to place portal lights at the windows.  You can click the screen capture to view a larger version if needed.

From that point I added four portal lights to the windows (set to use the environment, not skylight since I don’t have one in the scene) and enabled GI (Global Illumination) & FG (Final Gather) and fired off a test render:

Notice the large spots/circles?  You may want to spend time tweaking the GI settings or the mr Sun settings to try and remove these but that’s not the actual problem here.  I’ll disable the mrSun and render again to show that it’s not related to that light source:

As you can see, the spots are still there even though the mr Sun is disabled.  The reason I’m not getting a smooth GI solution here is actually due to the mr Physical Sky of all things.  Notice all the white spots where the direct sunlight should be?  That’s from the visible sun disk in the mr Physical Sky and picked up by the portal lights & FG.  I prefer to remove that because if you don’t you’ll need a lot of sample to clear that noise, plus it of course adds to the direct sun light which can often become too hot/over-exposed.

NOTE:  I believe that it’s also mentioned in the 3ds Max documentation that the mrSun shouldn’t be behind the portal lights.  I assume for this reason or something similar.  So hopefully this adjustment will allow you to place the sun wherever you want/need and still prevent these lighting artifacts.

To “fix” this problem I’ll instance copy the mr Physical Sky shader from the scene environment to the material editor to make adjustments. Here’s what the default sky looks like:

I will adjust the Disk Intensity and Glow Intensity values to 0.0 and decrease the sun disk scale from 4.0 to 1.0, although that doesn’t really matter when the disk & glow values are set to 0.0.  The adjusted sky looks like this:

Now the super bright sun disk is no longer there.  It’s now just a nice soft gradient that will play much nicer with your photons (GI) and/or final gather options.

I’m now ready to render again after making this simple change to the mr Physical Sky, and nothing else:

Yaay!  No more big white circles/spots/etc…just some more easily fixed blotches due to the low quality FG settings I used in this test.  So with that resolved I will now enable the mrSun, increase the FG preset to medium, increase the anti-aliasing (min:1 / max:16) and render again:

Not bad.  It’s missing a small detail though, and that’s photons from the mrSun.  Notice how cool feeling the image is?  During my tests I prevented the mrSun from generating GI photons therefore I’m not getting any warm colored photons from the sun in this scene.  Some may actually prefer this look since the sun photons are typically a lot stronger and can overpower a scene unless you manually edit it’s values.  Here it is with the sun photons enabled (and adjusted, more info on that below):

It’s a bit warmer and brighter with those photons from the mrSun.  In case you’re not sure how to disable photon generation on a light, here’s some captures to help explain that:

With the mrSun/daylight system selected, scroll down to the mental ray Indirect Illumination rollout.  By default it’s configured to emit photons when GI is enabled via the “Automatically Calculate Energy and Photons” option.  Uncheck that option and also leave the Manual Settings disabled and no photons will be emitted from the light source, in this case the mrSun.

Also make note that I have decrease the multiplier on the mrSun from the default value of 1.0 to 0.2.  I did this because at the default value it often seems like the mrSun is just too strong (IMHO).  It is quite powerful on the indirect illumination side of things as well and that’s why I have also decreased the GI Global Multipliers on the mrSun (also located in the mental ray Indirect Illumination rollout of the mrSun).  I decreased the energy to 0.5 and the photon multipliers to 0.25.

If you don’t do this edit to the mrSun photon energy then the mrSun will generate most of the photons in the scene, unless you specify a number of photons in the manual settings.  I know this may be somewhat confusing, that’s why I’m providing the scene file at the end of this article.  I discuss it further in some of the gnomon videos I made a while back.  But basically if you’ll open the mental ray message window and follow the information it generates as it prepares the scene you’ll discover how brighter light sources generate more photons than less bright light sources (as to be expected).  However, I would usually prefer to modify that behavior a bit to achieve more even light distribution in my scenes.  At the cost of physical accuracy I suppose…but hey, it’s all about getting the desired look no?

While I’m discussing all this, let me address another frequently asked question.  Why do I have so much blue in my scenes?  Simple answer, it’s because the sky is blue.  The portal lights are picking up their color from the sky and the sky is blue in this case.  What if I wanted less blue?  Easy.  There are controls on the mr Physical Sky for this.  Just uncheck the “Inherit from mr Sky” option on the mr Physical Sky so that you can edit it’s settings.

In the Non-Physical Tuning parameters, decrease the saturation level as desired to reduce the intensity of the blue in the sky.  You can also try tuning the kelvin values on the mr Physical Exposure control, but that affects the entire image which may not be desired.  This only affects the sky itself and thus the color of the light produced by the portal lights.

Less blue as you can see…a little to flat for my taste so I increased the saturation to something like .35 for the final image:

I know that’s a lot to cover in a blog post, so HERE’s the file that you can download and explore. Sorry, I can only save back to 3ds Max 2010 format.

UPDATE: Here’s an OBJ version of the scene for those not using 3ds Max.

New Getting Started Videos for SketchUp

Our Official Training Videos have been responsible for teaching literally millions of people to use SketchUp. Concepts of SketchUp, the first video in the old series, has been viewed over 7 million times. Collectively, people have spent something like 40 years watching that video. That’s a lot of popcorn.

As popular as they were, our old videos were getting a little long in the tooth; they showed SketchUp 6. We decided that they should be remade, so we locked Tyson in a closet with a computer and a pile of army rations. It worked—our new training videos are not only current, they’re gorgeous. With Tyson’s scripts and visuals (and Alex’s melodious narration), getting started with SketchUp has never been easier. Here they are, in order:












One more thing: We didn’t stop at the videos. We gave the whole SketchUpVideo YouTube Channel a facelift. With helpful navigation menus in the upper-left corner, a new masthead and a big, blue Download button right at the top, SketchUp’s home on the world’s biggest video sharing site is now a whole lot lovelier. Pop on over when you get a chance.

Project Neon – Revit 2012

image

Be sure to check out Project Neon for Revit 2012.

http://neon.labs.autodesk.com/index.aspx

Project Neon has recently been updated to allow you to do cloud based rendering from Revit 2012. Just sign up, download & install the Revit 2012 plugin & you are good to go! I threw a couple of render at the system today & I am very impressed. It will even notify you once you render is complete!

image

Once the plugin is installed, you will find another tab which allows you to publish your render online or to view your render gallery.

image

The images can be rendered using all the normal settings with Revit. You simply click the “render online” button, pick your 3d view you want, set the image quality, then the image size, followed by the File format. You have three file formats to choose from PNG, JPG & TIF ; then just hit the “Start Rendering” button.

image

Your file is the published to the cloud where a host of super computers rip through the render in no time at all. Once the render is complete, you are alerted via email. Login to Project Neon & you can view & download your completed render from there. You will need to set up the exposure settings on your host workstation before hand but that's a small price to pay for the speed of rendering. Be sure to give it a go! This is genuinely an exciting development for the Revit user & harness the essence of cloud based computing.
