Reflections

[al]

Reflections do not occur when rendering a 3d view aligned to an elevation view. Only some of the environment settings work when oriented this way. Any ideas. .... Revit / Accurender just @!#%!!!!! crashed again while rendering!!!!!!!!! Accurender is completely useless for this model I am working on!

View Culling Off ?
Sky settings ?
Sun settings ?
Cloud settings ?
Reflection bounces ?
Transparency bounces ?
Back face culling Off ?
Rendering quality ?
Many RPCs ?
Many Plants ?
Image size ?
RAM ?
Graphics Card ?

There are so many possible factors its hard to give an answer.
To "debug" a render you could start with the simple stuff - Draft quality, solid sky, no clouds, no reflection or transparency bounces, cut out the RPCs and Plants, etc, etc, and do partial renders working up in complexity from there.

Al-

No response from beegee's post. Did you get your problem solved or still need help? - Post the project or more info and I'm sure many will help. Your crash sounded like a hardware issue - more than likely either memory or harddisk space. Try beegee's suggestion - low res, draft mode. If it works step up the rendering in complexity.

I crash quite a bit with this particular model. Usually when I run it at higher quality - good or better it often crashes. 1 GB RAM 3.2GHZ HT. It is a large model. The Revit people say because of the way the elevation view is oriented it will not reflect anything. The camera placement is very strange and the crop region is on be default and set strangely. Do you think it should be working?

Sorry, Al without more information like beegee says, I can't say. You said "the Revit people" - Are you talking reps or the Revit technical staff?

Can you post at least a jpg of the hidden line image you are trying to render?

when you say the camera is in a strange location what do you mean? If you go to a default 3d view, then right click on your render view and select show camera, where is it? If for some reason its not looking at your elevation and it is positioned in such a way that if you project a line from the camera to your glass and pretend that line bounces off the glass, is there anything to reflect? If not place some trees or fake buildings in that location to give the glass something to reflect.

Another option is to add a map to your glass material, take a photo of what you would like reflected, mask it say to 20% transparency and add it to your glass material.
