Re: Bulb Glass

Its not geometry, but an issue with the number of reflections/refractions that are allowed before V-Ray stops calculating them. Reflection or refractions can be bounced back and forth between two objects till infinity (think of two mirrors on opposing walls). Calculating multiple reflection or refraction bounces can become quite computationally expensive, so V-Ray has a parameter in Global Switches called Max Depth that will limit reflections and refractions to that number of bounces. The default is 2, which is fairly low, but quite adequate in most situations. In yours, however, it isn't, so I would recommend changing it to something larger. Larger numbers (and therfore more bounces) will take a little longer to render though, so I'd start at 5 and increase it by a handful of bounces until you get a better result.
