I am rendering an interior view of a room within a Revit model. There are windows and light fixtures. for the first test, setting was set for small size, Biased Packet Mode. The resulting rendering was that of two cross members that filled the screen, no other details and no background. I tried changing the image size and rendering engine without positive results. In one of the other engines, the process was very slow and the resulting image was a black screen.

I have been able to get results for an exterior rendering of a separate project.

My version is QE02rv.

Any clues?

For the model with problematic interior rendering effort, I attempted a rendering of a cut-away view of the targeted area.  The view was an axiometric image, no perspective. The view uses the section box in Revit.  The view was zoomed into the small area of the building that remained after the cut-away was implemented. In the rendering, the impact of the cut-away and the zoom-in was ignored. The rendered view was of the entirety of the exterior of the model.  

If I correctly recall, I believe that earlier versions of Accurender rendered the image in place and honored the attributes of the view created in Revit.  Is there a way to handle this type of image?

Is is possible to send me a model with a view and section cut like this?

I can try it here and see what I get.

You can use this link to send us a model:

Thanks,

I tried to render exterior orthographic projections for the model of the building with no results.

First case, I tried to render an "Elevation View". A partial image was displayed as a narrow ribbon along the top of the image.

Second case,  I tried to render a elevation using the rotation feature for viewing the 3D model. The result was a black image.

Am I missing something? 

It's hard for me to tell.

If you could send me a sample model and a screen shot of what you are seeing, I could try to duplicate it.

We posted a new version of nXtRender for Revit on our downloads page:

http://renderplus.com/wp2/download/

which now uses the Revit Section Box for clipping the view in the rendering.

Please try that when you get a chance. 

Please note that we do not close any walls or floors what are clipped in the rendered view. I do not see a way to get those faces from the model.

I see what you mean. Thanks for the effort.

I have having other issues: The program does not seem to work the way previous versions have worked.

The following issues are true for whether or not the Section Box is used on the model.

1. I cannot get HDRi skies to display.  In addition, the HDRI selection button turns off when initiating render. Selecting HDRi under the Sky tab does not seem to work.

2. I see no way to adjust the direction of the sun.

3. I cannot seem to get shadows and shade to function.

When using the Section box, the Sun does not light interior wall faces. The surfaces are black even with ambient light set to high and the Light Balance slider is set to 1 (More SKY/Ambient).

When using the Section box, the ground plane is not displayed.

All in all, the results are not usable. This is very disappointing. I have been an Accurender customer since the earliest release.

Please experiment rendering the model that I sent. Perhaps you could advise if there are secretes on how to get the expected results.

Respectfully,

Jerry

I tested the things you mentioned and posted a new version on our downloads page, with fixes to make the Sun and Sky work better. Please download and try this latest version:

http://renderplus.com/wp2/download/

 

To set the Sun position in Revit, you will need to use the Revit Sun Settings dialog:

 

I fixed this to work better to get the same Sun Position that is shown in Revit. The "Relative to View" option still needs some work to figure out what they are doing with the Sun Altitude when you use that "Relative" mode.

We used to have a dialog in AccuRender for Revit that would let you set the Sun Azimuth and Altitude manually, to override the Revit Sun Settings. We stopped including that starting with Revit 2014, assuming that users just wanted to use the Revit settings, but we will put that dialog back into AccuRender for Revit. That should make setting the sun position a little easier.

I fixed the Options/Sky tab, so that you could adjust the Sun and Sky intensities and Cloudiness to balance the Sun and Sky again.

 In order to see an HDRi sky behind a rendering you will need to be in a perspective view:

An Ortho view, with the ground plane enabled, cannot show a horizon, so no background is possible, unless you use a perspective view..

We do not currently have a way to show the full ground plane in a section box. The ground plane gets clipped by the Section Box along with the geometry.

Here's the sectioned view when I render it:

I am not seeing the black walls that you referred to. But I don't see shadows in the Revit view either.
