Closed, ResolvedPublic

Description

System Information
Operating system: Windows 10 x64

Blender Version
Broken: 2.80 26d5a3625ed
Worked: 2.79b

Tested with the collada, obj and fbx exporter, I have not tested all exporters and if this also affects other modifiers (the array modifier works for example).

Exact steps for others to reproduce the error
Add a curve, add a curve modifier to an object, export with the apply modifiers option enabled.

Can confirm this is not working for curve-modifier-deformed objects.
(Array modifier seems to works fine though?, also checked Bevel, seems to be fine as well)

Reason being that
me = ob.to_mesh(depsgraph=bpy.context.depsgraph, apply_modifiers=True) seems to return undeformed mesh here?

@Bastien Montagne (mont29): there is also T58856 (and I will merge this report into T58856 -- so this we be off of your desk... of course you could still claim that one if you think this is for you...)

Reopening, merge was not a good idea, though related those two reports remains separated problems.
