Issue description and reproduction steps

Hair Curve objects simply won't display in the render. I initially thought it was linked to #277, however realizing instances doesn't fix the issue here.. Actually, even substituting the default curve input with a primitive mesh it still won't show up in Malt. So I think it's down to the object type itself.

Not getting any errors in the logs or console, just the usual stuff there.

This is not really a bug, more like a missing feature.

I just tried to add support for them, but converting a Curves object into plain geometry always results in Blender throwing an error: Object does not have geometry data .
It throws this error even when generating actual geometry inside the hair Geo nodes.

I found a workaround, though.

You can convert the curves into geometry:

And then copy the geometry from an actual mesh:
