Hi OK this is an old thread but support of RAW images may be fine.
I am using Hugin version 2013.0.0.4692917e7a55 on Ubuntu 14.04. RAW files does not seem to be supported because I get the following error : Could not decode image: P6140137.ORF Abort I have imported this picture generated by Hugin from two JPEG files https://commons.wikimedia.org/wiki/File:Cale_plouer_hugin_2014.jpg The defect is the wrong contrast between the left and the right pictures (see the little girl in the middle of the picture). If Hugin could support RAW images, this defect could be corrected by Hugin.
