High Quality Renders from Revit Stalling to Stand Still

We have been having an issue in our office the last couple weeks with High Quality Renders not rendering to an Image File.

Describing the issue we can bring up the view rendered in High in Enscape but when we click “Render Image” and select our file location the bottom Meter comes up but never moves. We have left it on for hours and no movement. We are using Revit 2018.3. This issue is on every computer in the office we attempt it with.

This isn’t an issue with Sketch Up; High Quality renders fine. Also we can get Draft Setting to work on fine on Revit. We have tried uninstalling Enscape on every computer but the problem persists.

The file is a pretty big one but it was working fine for months until a weekend a couple weeks ago. I have purged out Worksets and model links we don’t need for Renders in this Render specific model. It might coincide with our IT downloading Enscape 2.6 but I’m not sure.

Ideas we have:

RAM issues? Our computers say it is suing about 78% of our RAM space with the model up and Enscape. Is that too much to complete a Render to image?

Issues with Enscape 2.6 and Revit 2018.3? Has anybody heard of others having these issues?

Any help on this matter would be greatly appreciated!

Following up

There is one computer in the office we found still has Enscape 2.5.1 and the same renders that were crashing worked on Ultra setting. So it does seem to be an issue related to Enscape 2.6.

One thing to note about Enscape, which is different than most renderers.

When the Enscape team gives us more “automatic” quality without providing us the means to adjust those settings there is always going to be the chance that something which successfully rendered before no longer will… and we can do nothing about it except roll back to a version that did work.

So, what I highly recommend is that for every project you complete successfully keep notes as to what version was used, and keep a copy of those installation files. When all else fails you can always roll back.

Not a great solution, but unless they provide us more control over settings I suspect that will continue to be a random issue to be prepared for.

As a request, I would like it if the files saved from Enscape could include meta data as to what version was used. Is that possible @Demian_Gutberlet ?

I’m really sorry to hear about this - as I’ve not been able to reproduce this issue at all, could you please very kindly send in a dedicated feedback report as described here? In the submission form, please also be so very kind as to paste in what you wrote in the initial post, or a link to this forum thread! Thanks a ton in advance.

It may very well be related to the hardware of yours, but the feedback will tell us more exactly. Also, you probably experience crashes when trying to render in Ultra as well with 2.6, correct? What is the graphics card you’re using? I strongly suspect that the cause is either outdated graphics card drivers, or not enough VRAM plus a combination of a large project, high quality settings and large export resolution.

@renderwiz , I’ll gladly forward this accordingly - thank you for your feedback, too!
