All elements turn red when exporting to NWC

[lmcclungL4Y6M]

I am trying to export a sprinkler with an obstruction zone. I have set the material to glass, however when I export it to NWC everything turns solid red.

I went to 'V/G Overrides Model' and changed the object style of a pipe to black. I then exported to NWC and it made the pipe red instead.

Any ideas on the solution?

Hello,

I made a test here and got it transparent, maybe a material setting.
