how to export to x-mesh

[NIC_HAMILTON]

hi 
novice user here so excuse the stupid question....
trying to export some tyflow sims (grain stuff) to xmesh but not worked out how to do it? i keep getting empty 2kb xmesh files.

it works ok when i try it on spline plexus scenes though. 

any pointers here?

Your particles need a mesh operator, set to trimesh. You may also need to disable 'render only'.

thanks!
ah i had to add a shape AND a mesh operator into it.

wonder if any online render farms support this yet?
