Well, that would be possible, but the whole point of not storing render meshes is that they bloat up the size of the 3DM file by a large amount.

If MoI generated 3DM files that had render meshes in them and just ignored them on load, it would cause a large increase in file size without any benefit for regular MoI users since that data would just be ignored.

Making huge files with no benefit for regular users is not that great of a feature.

Isn't that a different thing than whether to store render/display meshes on NURBS objects in the 3DM file or not?
