Natural light not rendering in cloud

I am trying to render a 3D view in cloud but unfortunately the cloud does not render the natural light. When I render the image directly on my computer I have the natural light on my renderings. How could I fix this problem? I rendered a lot of views on this project and it never happened.
 
Thank you

Hi @Anonymous

 

There are some best practices to keep in mind when rendering on the cloud.

It is possible to select the Location/Date, Sky Model, and Legend Settings for optimum daylight rendering effects. Work through these tabs shown below to set the simulation settings for the rendering. 

 

Workflow

1. From the View ribbon, select Render in Cloud

 

2. You will be prompted with the following screen. It may take a few seconds for the dialog box to appear. Select a 3D View for the illuminance rendering. You can select one or multiple views to render at the same time.  The 3D views in the dialog box correspond to the 3D views you created in your project (See Setting Up Your Revit Model for Illuminance Rendering later in this playlist).

 

3. For Output Type, select Illuminance

 

4. After selecting Illuminance, you will be prompted to select the Location/Date, Sky Model, and Legend Settings. Work through these tabs to set the simulation settings for the rendering. 

a. Location/Date

The location for the illuminance rendering is always taken from the Revit Model Location. You can learn how to set the location for your project on the Specifying the Project Location page.

The date and time to be used in the rendering can be set in the dialog box. Alternatively, all 3d views contain a setting for the date and time, and this setting can be used automatically. 

b. Sky Model 

The Sky Model tab features 6 different sky models for the illumination rendering, and also allows you to specify the sun’s intensity (irradiance). Use this tab to select the sky model that best suits your needs and enter irradiance values appropriate to your location.

Good sources for weather data with irradiance values are Green Building Studio, where you can download CSV format weather data for your Revit project location, or the DOE weather data site

See more in: Sky Models & Irradiance Values later in this playlist

c. Legend 

In the Legend Setting tab you can set:

  • Units (Footcandles or Lux) – the measure of luminous flux per unit area
    • Lux is the metric or SI unit equal to one lumen per square meter
    • Foot-candles is the English or IP unit equal to the illuminance cast on a surface by a one-candela source one foot away
  • Scale Range:
    • You can choose to specify the minimum and maximum values 
    • Alternatively, you can select “Automatic” to have the scale’s range set based on the minimum value and maximum value (95th percentile) calculated in the simulation with 10 proportional subdivisions.
  • Scale Increment:
    • By default, a linear scale is used with 10 proportional subdivisions based on the range chosen.
    • If you choose Logarithmic, the scale will be logarithmic so that you can more easily visually distinguish between values in the lower portion of the range while still capturing very high values.
      • This scale is particularly useful when you select an “Automatic” range because it’s important to be able to distinguish between zero and 2,000 lux for interior lighting design. With a linear scale, the “Automatic” range often renders these critical values within the same color increment.
      • The human eye can function over a huge range of illuminance values – and a logarithmic scale better represents how we perceive levels of brightness. 

See the Autodesk Sustainability Workshop for more on measuring and perceiving light. 

 

5. Set the image size to set the resolution of the rendering.  Note that the resolution will influence how many cloud credits the rendering will cost you. You can find more information here

 

6. When you have completed your selections, select Start Rendering

 

7. When your renderings are competed you will be notified with a pop up window in the lower corner of the Revit screen, and by email if you selected that option. You can view the renderings by selecting Render Gallery in the View ribbon from Revit. You will need to login to Autodesk 360 in order to access the images. Your Autodesk 360 account is the same as the account you use for Revit.  

8. Note that you can re-render the same scene using different illuminance settings directly from the Render Gallery, without using Revit (it will use the same geometry, materials, and camera view from the original Revit render). See “Rendering from the Render Gallery” later in this playlist.
