Hi tapun19,
Can you re-attach the screenshot. But this time click on "Show details" so that we can see what does exactly the error say.
Thank you!

Hi Rodion,

This is not similar yet it is an issue. We know about it and are currently working on solving it.
There is a path to an asset, a rvt family or a rvt link which is too long and is causing this error.

Here is what you can try as a temporary workaround:
1. Create a copy of your Revit project
2. First start unliking all linked models (if any) one by one, render and see when the error will stop popping
3. If it continues, then start deleting loadable families (one by one or on small groups; this depends on your project size), render and see when the error will stop popping
This will help you isolate which is the object that cannot be exported properly. Once you find it, you can open the original project and 1. either remove it or 2. copy it to another location and reload it to your project.

Let me know if you need further assistance.

Hi Ana Lyubenova ,

I am also having the same problem; has this issue been solved?
Is there a better way to resolve this without deleting families in the model?

Thanks,
Derek.

Hi Derek,

Which V-Ray for Revit version are you currently using?
