Hello again, caddman97 - thanks for the details.
The reason I asked you to register your license is that some of our new licensees forget to register their (commercial) licenses, so we usually advise new forum users with company email addresses to register their license as the first step due to the fact that we have dedicated (hidden) sub forums for different subjects such as
Import & Export Questions.

It's not necessarily a problem that you're using
Lumion Demo 5.3 (unless you're using Windows 8 or 10 - more on that below). However, I ought to mention that the
Demo version of Lumion is 1 1/2 years old, and has several limitations in terms of content and functionality. If you're interested in a more in-depth evaluation, I would recommend our
fully functional 7-day Trial version of the latest version of Lumion (6.5.1) which we offer via your local reseller. This version includes all functionality and content of the full version, and provides a more realistic impression of what to expect.

Now, with that out of the way, let's move on to the DAE file issue you brought up. The file size limit varies from PC to PC, depending on your graphics card memory, system memory, virtual memory (harddrive swap space) as well as which version of Lumion and Windows you're using.
If you're evaluating
Lumion Demo 5.3 on Windows 8 or 10, there is unfortunately a Windows-imposed memory cap of 4GB for Lumion. Once Lumion exceeds 4GB it will crash or stop responding.
In other words, if you're using Windows 8 or 10, I would strongly recommend that you evaluate the 7-day
Trial version of Lumion 6.5.1 which has no memory cap in any of the Windows versions. That way, Lumion will first use the available graphics card memory (very fast), and when that's full up it will use system memory (quite fast), and finally when that's full, it will use virtual memory (very slow harddrive swap space).
That being said, a 2.1GB DAE file is indeed very large, so the first thing to check is what the
Geometry Accuracy slider is set to in the
Revit to Lumion Bridge plug-in. The rule of thumb is that you only ever need higher slider settings for rounded surfaces, so try to set it to low or medium and export it again to see what it does to the file size.
If that doesn't help, we will request some more information and ask you to upload the Revit file as a next step, so we can take a closer look.
Which version of
Revit + the
Revit to Lumion Bridge plug-in are you using?
