Viz. texure-how to do transparent

[Lily]

Hi,everyone

So I'm new to Vizard, 3d modeling. I recently encountered 2 problems,

1. I imported one room model which I created in Maya, one wall of the room is transparent just as glass. But when I imported into Worldviz, the wall just was black, what should I do to make the wall looks transparent in worldviz?

2. when I imported the room model into worldviz, it had no lights even I have added lights when I created the model in Maya, so when should I do to light the model?


Many thanks for your help!!
