The channel names in Krakatoa are case-sensitive. Your files have a channel βidβ where Krakatoa is looking for βIDβ. For more information on channel names, please refer to: http://www.thinkboxsoftware.com/krak-particle-channels/.
If you donβt want to resave these files, you can fix them by adding a KCM on top of your PRT Loader that copies the βidβ channel into the βIDβ channel. Then your Krakatoa PRT Update operator will show the ID channel and there will peace on earth. Well, one of those at least.
I win this race Bobo!
