Are there limits on the file size that irisVR can handle?  I have a large Revit model (over 4gb with all linked models) that has successfully published.  It is a stadium model and has a lot of extra geometry in seating that isn't really necessary but I wanted to see how much irisVR could take and still function.  Needless to say, with the side of this project, I am very impressed!  The only snag that I have hit is now that it is processed, I can't seem to save out an IVZ.  It spins trying to save it for hours and then just quits at some point.  Is this the byproduct of the file size or something else going on?

  Hi Taylor, 

  I believe your intuition is most likely correct, and your computer is likely running out of memory when exporting the IVZ file. In order to maintain optimal performance in VR, I'd recommend sectioning the model to specific portions you'd like to view in VR, or limiting the models that you're linking to geometry that you'll be looking at that in the VR session. 

  We don't have a file size limit for file imports, though at a certain file size you will experience degraded performance, this point being determined by the hardware you're working on.

  10-4, always fun to push the limits though - right?  Performance wise, my 1080ti handles it pretty well.  A little stutter but we are talking about A LOT of polys.  I will dial things back and see at what point I can get it to allow the IVZ to be exported.

  OK, so I have another model processing and would like to apply some metrics betweent the options by comparimg file sizes of the three files that I have ran through Prospect on the Prospect side of things.  Where would I find the files that are in my Prospect list of available projects but do not have IVZ's saved out?

  You can access the saved experiences in your library by navigating to the following directory on your computer: 

  C:\Users\USERNAME\AppData\Local\prospect-data\Library\exports

  Each of the folders in this directory represents a saved experience. If you open the folder and then subsequently the "log" file contained within, you'll be able to find the original filename and compile the information that you're looking for. 

  Let me know if there's any additional assistance we can provide!

  Hi Taylor,

  Often people in Revit model with way too many triangles. Also, Revit is horrendous when creating curves, it makes millions of useless triangles.

  The best way to troubleshoot is to export to 3ds Max and sort the objects in the Scene Explorer by the number of faces, then you attack the biggest culprits.

  

  The usual suspects are topographies drawn as curved lines, columns with fillets, railings and furniture downloaded from the internet.

  Last month I was able to go from 24 millions triangles to 2.6 millions triangles by attacking a few strategic families in Revit and the whole thing took about 3 hours.

  For example,you can probably simplify these chairs and remove parts that don't affect the architectural components on the project.

  With that being said, it would be great to have a tool to count triangles in Revit family editor, in the Revit project and in Revit. This would make users more triangle aware.
