in CM showroom , select the glass and then turn on transparancy... (beware it alters the kn5 file , cm makes a backup first though - but you will not be able to enter online server w your fixed car if the server is running the original car... )
A totally different question from me: anyone knows a fix for these blank previews lately?

with CSP for final render on , the generated rendered preview pic is showing no car, while the car is centered visibly in the preview pane. Tried also on/off all the ceckboxes visible in my screenshot...
