Cheetah3D 4.6.2 was released today. Version 4.6.2 is mainly a bug fix release but it also adds support for the Mitchell pixel reconstruction filter which allows sharper renderings than the formally used Gaussian filter. This version also improves the FBX exporter, especially if you want to import the Cheetah3D generated FBX files with the 2009 FBX SDK.
Cheetah3D 4.6.2 will be probably the last 4.x update before the release of Cheetah3D 5.0. If you bought Cheetah3D 4.x after the 24th Jan. 2008 you will be already entitled to a free update to Cheetah3D 5.0.
