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.
