Errors on exported model (Revit to glFT)

Hello guys,

I'm testing the simlab extension to convert revit(2020) models to GLFT.
I'm using the sample model rac_basic_sample_project.rvt.

Viewing the model looks kinda ok, my main issue is that transparent materials are opaque.
(I can't see trough windows.)

Probably that's my problem, not a problem caused by the simlab exporter but a problem with my renderer.

The other problem is obviously a problem with the simlab exporter:
82987 format validation errors.

I know that they are validation errors and that this errors are not critical for displaying the model...
But It's ugly, and there is a lot of them...

So, basically my questions are, why so many errors?
Is there a plan for correcting this validation errors?

I hope this will not be a problem, because I've found this extension to be super useful and I would like to propose my company to buy it. But I need some sort of explanation about this because it worries me.

I need to trust the exporter to use it.

Bellow follows the report with one "unique" error for each kind, for easy review.
