Sorry about not seeing this thread earlier. I was going back and reading the osg-user and osg-submission threads about the AC3D clamping issues and saw reference to a thread where I had not replied. That mention caused me to search out this thread.
I think it may be too late to have anything changed, but I'd like to learn something out of this matter. I still consider myself an OSG neophyte, so goes easy on me. You proposed two solutions: 1. add an ac3d options struct 2. install a read callback in the osgDB::Registry of your local application where you modify the texture parameters On #2, is this the same as the NodeVisitor that Robert references in the "Call for feedback" thread? On #1, is that just a class derived from osgDB::ReaderWriter::Options with attributes added for specifying repeat and clamping preferences? Thank you for all of your work on this issue. My apologies again for not responding to this thread sooner.

Hmm ok. John, I intent to make the ac3d loader load files like they are in ac3d. That is with all time texture repeate on and default to 1. For your problem I can see two solutions: * add an ac3d options struct * install a read callback in the osgDB::Registry of your local application where you modify the texture parameters will thet read callback be an option for your problem? If so, I would prefere this solution.
