Thanks! It looks like somehow https://github.com/libgdx/fbx-conv/commit/69405446289281d15b1a0d178deb44b6edbb77fe reverted #52. Should be solved now. Would you mind to verify and report back as I currently can't test on linux?

[andrepl]

Verified, working perfectly now, thanks.

I am still getting segfault on precomp binary for linux, I see the jenkins build has failed too-- unless I'm reading that wrong

[andrepl]

@viperscape looks like you're right, it broke the windows build, and I'm not sure if jenkins ever built the linux binary. the logs don't seem to show it, so the one you downloaded is probably the old one.

If you clone this repo and only run the linux build it should work fine, I'll open a new issue for the windows build :)

[viperscape]

I get a build error on make, perhaps I should open a new ticket?
