*A main reason why no third party has developed a plug in is that the Bryce .br5 format is not only undocumented, it's even encrypted! (So I'm told.) * It isn't actually encrypted, it's just in a binary format and much of the implementation is pretty unique. Bryce has basically followed a parallel but seperate evolutionary path over the years from most other 3d technologies. I pretty much have nearly complete data on the br3/4/5 file formats, so file convertors are definitely on the cards (it's on my business plan). However, the additional work required to achieve a full (live) data sharing plug-in is economically more questionable, and there's no data yet to indicate whether the Bryce API meets the basic requirements for such a thing. All we can really deduce from the existing im/exporter plug-ins is that the API supports the ability to add and extract data, which by itself is not sufficient for such a plug-in. Bill
