Hi Johan, I believe what we'd need to do is just enforce the rule that .osg files all use . for their decimal places, then constrain the writing and reading of .osg files so that it uses this convention. Reading is more straight forward, as it'd just require a modification to Field::getFloat() method and would certainly be a useful first step.
