Hi

Post work after the final Carrara renders  is not permitted. Only exception of course is using your video software for compositing shots and things like cross fade in / out effects and also the title and credits themselves but nothing to alter the appearance of what you make with Carrara -like colour correction or other video filters and overlays.

Carrara has plenty of tools to make a great animation and renders and this is what the competition and the website is about - to explore the capabilities of Carrara and your skills in using the available tools [not to mention your overall film producing/directing which is not an insignificant requirement in itself even though it is  only for a  2 minute movie ! ]

Yes you can use any of the built in tools or plugins available from  Fenric,Inagoni, Sparrowhawke Digital Carvers and Daz  but "plugins"  must be declared in the précis of how you made your movie ( required to be submitted with your entry )   

Don't forget to declare your intention to participate in the forum where you and anyone else participating will be warmly welcomed.

thanks for your interest in this .

cheers
