Hi All,

I've had great success using the method caecarvalho suggested - however I have just run into the issue where the transparency setting in the Vray material editor only adjusts the brightness/contrast of the material i.e. 0.25 gives a washed out look, but no translucency. The Alpha layer still makes the correct areas 100% transparent.

This seems to have happened for almost no reason i.e. models which have previously rendered perfectly now don't, and as far as I can tell there have been no significant changes to the models or to either the SketchUp or Vray programs.

Any ideas?

Hello Timothy,

if I understand right,I see you're trying to adjust the transparency in a wrong way. The correct way would be to use the color parameter in the tranparency option and not the number. What I mean by that is, if you want a 75% transparent text, you need to use a 75% gray color. You can leave the value 1. You will use colors from white to black, being black no transparency and white full transparency.
