iOS Physics and Particles
I've made a very basic top-down game where the player shoots small destructible meshes that explode when shot. When they explode they have a particle system spawn for the explosion.
The game looks fine when deployed to PC or Mac, but when I deploy it to my iPhone 4s the destructible meshes don't fracture/do any physics, and I don't see any cascade particle effects.
I've tried grabbing the config from the mobile optimized Tappy Chicken as stated in:
But I haven't seen any change. I'm guessing the issue is either an optimization issue or a config setting not being turned on. Any pointers on how to approach these issues would be greatly appreciated, thanks!

On the BlackBody node, I'm not sure why it's disabled for ES2. It's expensive ALU-wise but we typically leave those choices up to the artist. I'll TTP for us to change that.
On the destructible mesh, I'm not sure offhand. It may be that it is not chunked properly for mobile devices which have limitations on max bone count. That is a workflow we need to improve in UE4. In the meantime you could try setting Compat.MAX_GPUSKIN_BONES=75 in the [SystemSettings] section of your project's DefaultEngine.ini, and do a clean recook of your game for mobile.
Hope that helps!
