I modifed the FPS example to enable destructible cubes.
This works and deploys on windows.
On mac, it works in the editor.
But the packaged version doesn’t work in either ios or mac.
No error - the cubes just dont break apart.
Thanks in advance for any ideas/advice
Hi OptimisticMonkey -
Unfortunately, Destructible Meshes are not supported on mobile devices. Here is a link to the mobile content creation guidelines.
Thank You

Thanks Eric - What about using a destructible mesh when targeting the mac desktop ?
Hey -
Destructible meshes should not work in an OSX machine unless some very interesting setup is done which you are welcome to look up through Nvidia’s website. Natively though Mac’s should not allow destructible meshes (DM) to be created. Are you importing a DM from your windows project then opening it in your Mac version of the engine? If so, can you save the project, close and then reopen and still have the DM work in the editor?
Thank You

An alternative i use, (its a bit long winded) is to utilize the “Smash” Feature in blender, then import your broken meshes into Ue4. Create blueprint and re-assemble the individual meshes. Then in the blueprint with event overlap or hit, simply enable physics simulation on all parts. It still looks quite good, and although the initial creation process is much longer, once made it can be added to your levels as fast as a DM.
FYI - Just checked (4.13) and destructible meshes are working on mac! Thank you Epic 
Looks like they have since 4.4!
