Hi,

I have a hip file with a couple embedded custom HDAs and some vopsops operators in a file + some other external HDAs in the otl path. While opening my file with hython everything looks fine but when trying to load hou module into standard python script and load the file suddenly I am getting tons of errors:

OP: unknown error: 3
OP: unknown error: 3
PRM: unknown error: 5
PRM: unknown error: 5
PRM: unknown error: 5
OP: unknown error: 34
…

I'm suspecting some broken links to some operators, but what PRM means? I'm not sure what I am missing to properly load the file.

thanks for any help

I have more info about this problem:

looks like my vopsops create problems…

Did you source houdini_setup before starting Python? The “unknown error” messages suggest that $HFS might not be set.

Thanks Lucas,

Yes, HFS is set up properly. I got rid of all of the vop sops, all embedded HDAs I saved to otl files, moved scene contents to a new hip file and looks everything works and loads fine right now, strange I think my file was pretty messy….

Do you think embedding HDA's in a hip file may produce problems?
