Hi, guys,

I have a hip file with many nodes imported from a fbx file from maya.
We have a character in it, and there are lots of controllers linked together, so the hierarchy tree is very big, then I save the file, and reopen it, we got some error, saying that
Error: File read error - possibly corrupt input: Missing file extension:
twinsta Pkey???

Then I rename all of the nodes to make the name shorter, then save it again, it's okay.
The path of the bottom node has 490 characters. Is it because that the path is too long for houdini?

Then I flatten all of the subnet nodes into right under just one subnet node,
it's okay. Like this:

old:
/obj/abc_fbx/abc/ffff/ffdfd/…

new:
/obj/abc_fbx/abc
ffff
ffdfd
…..

Any of you guys met this issue?
