Revit 2014 - Cloud rendering creates spotty cove lights

[mvitale81]

I am pretty new with rendering in Revit through the cloud based service... I have been pretty satisfied with most of the lighting and shadows so far but ran into an issue with the cove lighting. I have attached a photo of the result. I have tried installing a strip cove light as a line & rectangle light I also tried painting the back face of cove as an emissive material. Either way I do it, it seems to render as the spotty image I have attached. Any ideas or suggestions to fix this issue?

Thanks in advance!

It's probably a function of the .ies file (which controls the "shape" of the light emitted by the source) attached to the light source.  Check to see which .ies file is being used, and if you can, find the one that goes with the specific fixture you're using (many manufacturers can provide this).

Thanks for the respose. I did attempt to adjust IES files. I also made the fixture itself a bit shorter in length and added more of them along the cove. This provided a decent fix for the time being, but it still appears a bit spotty. Would you have any reccomendations on how to achieve the look of a seamless, LED "tape" light? I have attached the results from adjusting the IES files, but like I said it's not quite there yet. I know I can photoshop it easily, but I also want to be able to render this as an interactive panorama (which takes away the option of photoshopping since its an html file). Any advice would be appreciated.

Thanks!

This is a known issue that is logged with our Development Group. Basically the rendeirng engine sometimes has trouble with long linear light sources. While we are actiavely working on a fix, we don't really have a workaround at this time. I have added this thread to the issue they are working on so that they know more people are reporting this issue.

Is there a resolution for this problem yet?

I also landed on this page after an extensive search.  I have attached a current rendering to show the same issue.  I am still running low quality settings because the project is in early development but you can already see the cove lighting issues.  Just wanted to let you know we are still looking for a fix. Any update would be appreciated. Thanks.

FYI it's still an issue, but the workaround is to use a shorter light source/fixture, and copy it to make up for the total length you want; the results are much better. Once the rendering is finished, you can adjust the exposure and increase the highlights, which will make the lighting from the cove lights a little brighter, but more even, since it masks the hot spots...

3 versions and 3 full years later and this is still an issue.  Have there been any updates to this?  

I don't like having to exponentially increase the amount of content I'm putting into a model just to get a light to look right for a rendering.

Paint Light Material for even distribution on the bottom of cabinets and up in soffits. I also use a slight amount self-illumination in wall paint, etc. Also, experiment with super high light levels.
