Howdy Alex,

Thank you for reporting this issue. I have tried a quick repro of this issue but I have been unsuccessful. I am going to need a bit more information from you on this issue. Which version of the Engine would you be using and would that version be a Binary or Source build or UE4? Always, is there a step by step way that i may be able to recreate this issue internally?

Any additional information would be greatly appreciated

Thanks!

Both Version 4.6.1(Binary) and Version 4.7 preview 4(Binary)have the some issue,
For test this issue, I have put 30 bolls model copied form the one, then I run build in editor and save,
I have map file become 1.4 MB,
this bool mode :
Triangles:
Vertices: 302
UV Channels: 2
Approx Size: 5x5x5
Light Map Resolution 64

Hey Alex,

Thank you for providing that information. Would you be able to share that model with me so that I may be able to test this issue internally?

Also, are you packaging your project using the Android (All) option or would you be packaging for a specific format? Would you be including starter content in your project?

Thanks!
