Linux 2014 Segmentation Fault

[Anonymous]

Hello friends,

I've encountered a strange problem with Maya 2014 whilst transferring a rig between computers. Back at home I'm using Win7 and my maya file opens fine on that plus 2 other Win7 computers. Whilst on my work computer running CentOS Maya receives a segmentation fault and crashes.

I ran a stack trace to see if I can get any info on this crash and this is what it gave using gdb :

0x00007fffde99fcfb in TuvSampler::copy(TpolySurfaceAssociator*, TattributeSamplerState&) () from /opt/autodesk/maya2014-x64/lib/libModifiers.so

the details it gave were (threw it in a spoiler tag so this post wouldn't be too big),

Any ideas on why this might be happening? All I can see in the debug info is that it mentions TransferAttributes? I imagine this error would happen on OSX as well, could it be a memory problem since it's a segmentation fault?

Thanks!

Update : Just deleted the blendshapes which had transfer attributes on them and the file opens fine, looking further into this!

Solved!

Turns out the rig has some stacked transfer attributes on a couple of the blendshapes. Cleaning these up since they weren't needed helped fix the file and it opens smoothly on Linux now as well.
