When rendering a windowed area of my project, the rendering only goes down to Level 1. It will not render the wall from Level 1 to ground level. I am sure it is just a matter of changing some settings but could you tell what the problem is?

Are you using the region raytrace to render part of a view? Or are you using raytrace to render a whole view and parts are coming out grey?
Or to steal someone elses words "Please explain"
Regards.

I am using a region raytrace.
Please look at the attached image. You can see where the rendering stopped. Below that level there should be another 4' of wall before you get to the ground.
Thank you.

For your view cutting off look under Settings/Environment/Ground plane and see if you don't have a ground plane set at this level. DO NOT Radiate an exterior view! To see your reflected items - uncheck your culling box under environment. For windows to become transparent in either direction, you need to set them using the daylights on the render menu.

Here are a couple of questions I do not yet have the answer to - hope someone can point me to a rendering tutorial or to provide answers to these questions: I have managed to create a rendered image using Ratrace or Radiate, with basic lights and furnitures.1. Raytracing and Radiate - do they work together, or are these two different ways to generate a render? The Radiate looks much more realistic, but it looks incomplete.2. When I use Radiate over transparent surfaces (windows, glass tables) the glass is black when the radiation is done. What am I missing.I searched the forums, but could not find anything that helps.Thanks very much in advance.

Radiate is NOT rendering. Radiate is used to look at second, thrid ...and more light bounces off of objects. When that happens, these objects actually become a light source with the light being their color. This is what will give you secondary shadows and color shifts on objects in interior renderings. This really brings these closer to real life but the cost is rendering time. When you radiate a scene, AccuRender makes a lot of complex caculations based on geometries - at this time, it really doesn't consider color. NOTE This is why you don't want to do an exterior scene. Radiate reflects the light to objects all around, including behind the camera. In an exterior scene, it gets bogged down with space that is infinite. After you radiate a scene, you should save this information for future use. As long as you don't change the geometry in the scene (move objects), you can reuse this information in multiple renderings where you may be changing object materials. If you want to see through glass in interior scenes, you must set daylights for the glass. Likewise for exterior scenes looking through glass. After you radiate an interior scene (and save it), you still have to render it. Hope this helps.

Hi, I have bene nusing Revit for over 3 years and I can't figure out how to use exterior lighting. When I render an image my roof is "always" way lighter then it should be in real. I tried changing the setting on the original texture jpeg but nothing seems to work. Can you please help me? Thanks

Regarding the question about how to make the roofing darker. The rendering engine in Revit is a little lacking compared to some other applications. I did a little experimenting and found a solution. To edit the texture settings, right-click the texture and select edit (See attachment 1). If you are using a texture map based texture for the roofing, use a ‘blend’ texture instead of just a ‘base’ texture (See Attachment 2). With the blend, you will see in the column on the left that there is an option to adjust the settings for the First material and Second Material. For the first material, use the image map of the roofing (See attachment 3). For the second material, you don’t need an image map, simply set the color to black. You can then adjust how dark the material renders by going back to the blend settings and adjusting the % mix of the two. See Attachment test Revit Rendering.
