Same FBX returning less meshes after upgrade to 18.5

Hello,

I am having an issue with some FBX models returning significantly fewer meshes after upgrading the library from 17.9 to 18.10, it seems like the version that causes this specifically is 18.5. Has anything changed in this version to make Scenes work differently or is it a bug?

I have attached a sample project to demonstrate this, it is built using the 18.5 version of the library. If you switch the NuGet package to 18.4 you will see the difference of the output.

Thank you,
Antonio

The upload functionality doesn’t seem to be working, the link for the sample project is here: https://drive.google.com/file/d/1F_ApHcypGjAyYKcQVRBGxyZq2PfJj7KM/edit

We have further investigated the ticket and figured out that the difference was result of some limitations for unlicensed use which were not being applied previously. Moreover, FBX import and export performance has also improved a lot in the newer versions which make the performance of this API second to none.

Furthermore, you may request for a free Temporary License to test the API in its full capacity before purchasing a license.
