When creating a rendered image, you may want a night time shot only using artificial lights in the room or an exterior view rendered using sunlight at a specific time of the day. You can easily get those results using A360 Rendering from Revit.
When you render in Cloud from Revit, the rendering engine uses the light settings from your Revit file. It looks at the Lighting Scheme that you have set for your specific View. Here's how it works.
In the View ribbon, click on "Render" and check the Lighting Scheme.
This scheme has various settings that can be used ranging from "Sun Only" to "Artificial only". Choose the scheme that's appropriate to the look that you are going for. This post describes it in detail.
If you choose "Artificial only" or "Sun and Artificial", the Artificial Lights button becomes active. Click on it to further adjust your artificial lights.
As always, render in "standard" quality first as a preview. It will be grainy but will give you a fairly good idea of you camera, materials and overall lighting. Once you are satisfied with it, render in "final" quality.
We are excited to let you know that we have made further updates to stereo panorama renderings.
Stereo panorama renderings can now be sent directly from Revit. In Revit 2013 UP1 and above, you will see it as an output type in the "Render in Cloud" settings window. Note that if you are using Revit 2012, you will not see it in the drop-down menu. But as always, you can render a still image and re-render as a stereo panorama from the My Renderings portal
Stereo panorama downloaded links (zip file containing pano.html) can directly be opened in the browser, Firefox or Internet Explorer. Prior to this fix, the html file had to appended with ?url=image or ?mono=image . This will not have to be done anymore and the link will work directly. Please note that since Chrome browser does not let you open local files directly, if using Chrome, you have to launch with this flag --allow-file-access-from-files. Example: file:///C:/Users/xyz/Desktop/stereo/pano.html
Some of you have asked how you could view stereo panorama renderings on VR devices such as Samsung Gear VR or Oculus Rift. The simplest way to view this on a VR device is using Cardboard and here is the blog post describing that viewing workflow. For a more immersive experience, you might want to use GearVR or Oculus. But understand that VR viewing technologies are ever-evolving and experimental in nature. If Samsung or Oculus change their viewing technology, things may become incompatible. This is not something that Autodesk can control. Here are the steps that work for now.
Connect your Oculus and download the required runtime files from here:
Make sure that everything is up and running and the Oculus demo works.
You will need a browser that supports webVR, either Chrome-dev or Firefox with VR.
Download the dev-version of Chrome. You have to look at your operating system and install the appropriate version. After you unzip and install it, open the browser and in the address bar type chrome://flags. Find "EnableVR" and enable it.
A stereo panorama rendering created using A360 rendering can be downloaded as a zip file.
Once you download the zip files and unzip it, you will see the following contents in it:
image.png - The main high resolution image
image.jpg - A lower resolution image for preview
imageL.jpg and imageR.jpg - The left eye and right eye images
pano.html - The html file
twgl-dist.js - Javscript file
readme.txt - Additional instructions
Here are the steps to adding your own custom background
Open image.png in an image editing software such as Photoshop
Since this is a png file, it has an alpha mask and you can composite your custom background.
Once editing is done, save this as a separate file or you could overwrite the original. But the final file has to be named image.png
Now you have to generate the left and right eye images and the preview image
Crop the top-half of the image and Save As imageL.jpg
Crop the bottom-half and Save As imageR.jpg
For the preview image, Save imageL.jpg as image.jpg. Reduce the size of this image to 1/8 of the original size. For eg: 9216x1536 will become 768x128 pixels.
All your images are now ready. If you want to preview how it looks on your computer, open Firefox browser (Chrome does not let you open local files) and drag pano.html to it. You should see a pixelated preview for a brief moment. After it clears up, you will see the new panorama with your composited background image. Example of the link: file:///C:/Users/xyz/Desktop/stereo_pano/pano.html. You should do this to check if your composite looks fine and if there are any edits required.
In order to view it in the browser on your mobile device (this is what you really want), all the files in the zip file have to be hosted to your website. They cannot be uploaded back to Autodesk's site, which happens when we generate a URL for your rendered stereo panoramas.
Here is the video that highlights and features some of the best customer images created using Cloud Rendering. Thanks to all our customers who contributed towards this. We will be featuring this video at AU 2015.

Shahriar Farzanehfar is an Architect with professional experience in commercial and residential projects. One of his most recent projects was a private villa for a client that consisted of renovating the first floor and adding a second floor.
“The major challenge in this project was lighting it to the impress the client,” he says. Below, Shahriar describes the techniques he used to light the building, resulting in this impressive visualization:
Shahriar’s lighting technique:
Set the camera:
2. Next, I used a source light that I downloaded from revitcity.com called “studio lamp”.
3. I then used a systematic arrangement for the lamps around the scene, especially in the false ceiling.
4. One of the most important parts in this process is to define the material for all objects. For example, to assign a material for the floor in this project, I needed to select a material and consider an appropriate number for its reflectivity. To achieve the right amount of reflectivity, I rendered the image at low quality to test it and see how it looked.
5. I also set up the model and rendered it to check the lighting of the scene.
As shown above, the figure scene lighting is low, so I increased the lamp lighting (in the edit type section), using the settings shown below. With these settings, the intensity of the lighting doubled.
6. Finally, when I achieved the proper lighting and materials, I rendered in the cloud at high quality!
This process taught me just how useful test rendering my scenes is to getting the lighting and materials just right. By rendering frequently at low quality, I was able to resolve the appearance issues step by step. At the end, when the scene is where I want it to be, I render it in high resolution. Seeing the result of that perfected, final image is the best.

This week, we’re turning to a Rendering Pro from our very own team, Aradhana Vaidya—the Customer Success Engineer on the A360 Cloud Rendering team. Last week, she hosted a webinar on the Cloud Rendering Workflow in Revit, which detailed how to share renderings to the gallery and select render settings to create the best possible images. She demonstrated how to produce high quality results with:
Panoramas & Stereo Panoramas
Illuminance Renderings and Lighting Analysis
Lots of new and experienced Revit users attended, and asked a lot of great questions. Below, we’ve listed some of the best questions (broken down by category) along with our best answers, which you can use to help you with your own rendering projects.
1. Why do renderings appear differently, colors, material, etc., when they are rendered in the cloud vs. locally?
Native rendering in Revit uses mental ray. A360 Rendering is the rendering technology developed by Autodesk to optimize rendering in the Cloud. We try to match closely with mental ray (with high quality settings) but there could be subtle differences.
2. We see a few renders with light emitting from can lights. How do you show light emitting from light sources rather than just the light affecting surfaces it hits?
If you want to render lights properly by showing the light fixture as a light emitting object, you have to create a material with “self-illumination” and apply it to the bulb or diffuser in your light fixture. These luminance materials are supported in Cloud rendering.
3. In some programs adding lights one by one is the best way to get a good final lighting. Is that also recommended in Revit renderings?
A360 Rendering can handle large number of lights very easily without slowing down the rendering process. So you can add as many lights as needed in your design. You do not need to add them one by one.
4.I have seen noisy or grainy renderings sometimes. What is the best way to get best quality renderings?
This might happen if there is inadequate lighting in your scene, such as indirect light coming from a window. If the scene is well illuminated, you will not see this problem. Add more lights to your scene or increase the intensity of the existing lights.
5.I was curious if Autodesk was working on enabling tint settings, as well as the reflectivity settings (in the slider) within Revit. Right now they don't render online.
Make sure you install the latest version of Revit--this should enable tint settings.
6. I am a student rendering in the cloud and I created a custom brick material. When i rendered in the cloud the brick size was huge. When I render inside of Revit the brick wall looks fine and everything is to scale. Why I am seeing this difference in my renderings?
For issues related to material properties such as tint or incorrect material scale, make sure that you have installed the latest update for Revit available here.
7. Can you use custom textures in cloud rendering?
Yes. You can create a material in Revit and use custom textures for color, bump, reflection, etc.
8.Is there any source for realistic materials?
There are several resources available online to download realistic texture maps. We don't recommend a specific site in particular.
1. When downloading panorama, is there a way to view it as a true interactive panorama (like it is when viewed directly in A360 Rendering)? In the past when I tried to download an interactive panorama to my local computer, it only downloaded a series of stills.
When you render a panorama, there are two options available for download. One is jpeg file, which is an image strip. The other is to download as an html file. If you do that, you can view it in the browser, preferably Chrome.
2. When downloading panoramas as jpeg is there a viewer available to view these? I like being able to download and edit the images via Photoshop rather than just having the html download from the cloud. If so can this be shared with clients?
We don’t have a viewer that we provide. But there are several viewers available online that you can use, starting with this useful website.
1. What other files types can be rendered besides Revit files?
Besides Revit, A360 Rendering is supported in AutoCAD, Fusion, Navisworks, Infraworks and 3D Studio Max.
2. Does a linked model get uploaded to the cloud when I do a cloud rendering?
Linked Revit models work with A360 Rendering. When you “Render in Cloud”, your Revit file is never uploaded to the Cloud. We convert it to an intermediate file format which consists of all the information required for rendering, such as the meshes, materials, lights, etc.
3.Can you render using A360 with Revit LT?
4. What rendering engine does A360 use?
This is our own rendering engine. A360 Rendering is the rendering technology developed by Autodesk to optimize rendering in the Cloud.
5.How many cloud credits do I need for a render?
You need approximately 1 cloud credit per megapixel.
