That's very sad. It doesn't make sense that Microsoft purchased Caligari and is now effectively shutting it down. Microsoft don't have any other 3D application in their product stable do they?

Anyway, I guess now is the time to download a fully mature 3D program for free. I'm sure there must be a huge Truespace community since it has been around for years.

Best of luck to all of the Caligari employees. It's all very sad.
