Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
I created this issue as requested here .
While the export of animated mesh objects works quite well, exporting and importing curve objects does not work as expected at the moment.
When exporting curves there are two main options:
Both of these are very useful. Depending on the specific setup it might not be useful to export a curve as curve but rather as mesh. Being able to export as mesh should always be an option.
I created a little test file that includes a curve object with multiple animated properties and modifiers: curve_export_test.blend
Some modifiers implicitly convert the curve into a mesh, so when the user wants to export as a curve, it should (if possible) evaluate all modifiers until the curve is converted. If it is not possible to apply only some modifiers, it should still be possible to only export the curve before any modifier is applied (next to the option to export the whole thing as a mesh).
Also, keep in mind:
If I had to choose what to develop first, mesh or curve export of curve objects, I'd vote for mesh, as it allows for more flexibility. Additionally I imagine it to be easier to develop.

Not too relevant anymore here. Development is being tracked elsewhere, and import has already been implemented.
