Hi Francois,
My apologies it looks like I missed your previous email on this. Let me
take a look at this and then follow-up. One thing to note is that you
want to be export single layers (that is the component layers that will
make up a glazing system) from optics. We are relying on the glaze
script to combine the layers and produce a usable material definition.
