Trying to find info on this topic but I haven't found anything..

I want to make white glass that is optically opaque, but allows light through (like the white glass on a fluorescent tube). Another example would be fabric shades on lights, visually opaque but lets light through. Any ideas on the settings needed to do this?

Also semi-related.. I see texture map options in photoview 360, but can you have an opacity mask? (beyond the perforated metal/chanlink settings included in the program)

Thanks SolidWorks community!!
