JM, I think Vlad’s point may hit the nail on the thumb. Now that I think of it, I’ve heard this from other folks with way more time outside of RC about problems with FBX. I agree, it’s a real shame having to deal with bloated file size and not bringing cameras along. At the same time, I’m not one to easily let go of a problem, see no reason to dismiss a possibility here; might it be that Autodesk’s FBX format missed it on accounting for an important detail like left or right-handed in how that information is generated, passed through the file, and listened to on the other end? Vlad, when you say buggy, I hear problematic due to some random variable, but how certain are you that this couldn’t be a case of something masking as random behavior, but in fact is predictable and based on incompatibility between two programs, RC and ZB in this case, where failure of Autodesk to account for something like left/right-handed causes the issue flipped up-axis? This issue, while real, seems at least consistently off, not random. Maybe, artists working in 3ds, Maya, Mudbox, ZB experience yet other issues unrelated to up-axis that indeed are “buggy”, but it seems the only problem between RC and ZB in FBX is limited to up-axis, might be worth making a distinction? Appreciate your insights.
