An update to Anim8or, v1.00b, is available with a few bug fixes. Get your copy HERE. See the "ReadMe" file for details.
"The only problem with exporting scenes with anim8or is that they must be in 3DS format there is no option for .obj Then there is the problem of figures they are not exportable and with characters that are sub-divided the software hangs with a too many faces exceeds limit 65535 error."
Ah yes, Carrara has a dreamy renderer ;PBut don't forget anim8or can export scenes in it's own format, but only anim8or can use it so far (hint hint) ;p
Encrypting files wouldn't make things any faster, if anything it would make them slower.
