Sure, yes the end result can be compound attributes, but what I'm wondering is whether compound attributes are the root cause of the problem, or if it's elsewhere. As a test, if you were to replace the compound attribute with a float, does it still cause trouble? If so, then we know to look more closely into the compound attributes. If not, then we could strike that off. Either way, being one step closer to success.
