.FBX export hierarchies?

Does the new .FBX file exporter include “hierarchy” information? I’m trying to export a model that has two child objects. The objects are exported properly, but the hierarchies aren’t.

Thanks!

yes, the latest exporter can export object hierarchy’s as well as animation on each object - tested to work accurately in a few apps.
If its not then I think you could have an old version? - the one with 2.45 does this IIRC.

Thanks Cambo,

I’m running 2.45 for OS X (UB) with Python 2.35. I’ve got two objects that I’ve made children of a third object using “CTRL-P”, make parent, and I’ve confirmed the hierarchy in the “Outliner” window. But when I export the file to .FBX, the hierarchy is lost and my objects are all on the same level. The objects are not animated, I’m just trying to set up a hierarchy for use in my game engine (Unity).

I think I figured out what was going on. I was using 2.45 -and- had an old version of the .FBX export script in my scripts folder. When I removed the old script and tried it, it exported the hierarchy as it should.

I did run into another issue though. My “child” objects became distorted. Here’s what they look like in Blender:

And in the game engine:

Any idea what may be going on?

this is odd - there are some differences in now applications handle loc/size/rot - there is no correct way.

blender can not do a shear matrix and it looks like this might be whats happening.

Could you check your scene for negative/extreme scale values? where possible use a scale of 1,1,1

failing that you can upload the blend and I can do some testing.

The work around for now is to export the scene in 2 pieces, but it’s a klunky fix at best. I’d gladly email you the .blend, but since it contains some confidential material I can’t post it here. Drop me your email address to info (at) marinesimulation (dot) com and I’ll send it to you.
