i am trying to export my fluid mesh in alembic but getting this error ….. is it because i need to install windows 7 service pack one or i am doing something silly here..

Is it possible to post the .hip file? Others can test it on other platforms for you.

the mesh seq which is in bgeo and i am trying to export is +400gb and one thing i ve noticed as soon as my alembic reaches 4 gb it got crashed , i can take any frame range but it does the same, i can upload hip but caches are in gb

changing the format to hd5f worked but no animation left

I can't recall totally but I think I've read somewhere that changing mesh count is not supported by alembic. Maybe it has changed in the recent version I don't know.
