Fenric has just released an update to his Object Sequence Exporter for Carrara PC/Mac:
Corrects some issues with inverted normals and fixes compatibility with soft-body physics.
Get it at the download page, where you also can get the free trial version before you buy it for only $3.
You will also find the other extremely cheap plugins by Fenric at the same download page, with free trials for all. There are also 2 free plugins, get them and support Fenric by buying his cheap plugins.
The Object Sequence Exporter uses a “baking” method to completely capture all of the vertex position
information about an animated object and exports it into a sequence of individual OBJ files, one for each frame.
