Vray showing PNG textures as transparent.

[kelvintaylor]

Hello, I'm having a very strange issue with Vray for Sketchup. I'm using a PNG in my model with alpha channels. The center is supposed to be clear. However for some odd reason Vray decides to make it fully transparent.

This is what it looks like in Sketchup (The black texture is a vismat)

 

And this is what happens when I render it in Vray

 

additionally I'm noticing that the window on the door doesn't seem to render either.
