Build a module in Debug mode

[Roy_Wierer.Seda145]

Could be that one or two engine macros do not work properly, I don’t know. These work:

#if !(UE_BUILD_SHIPPING || UE_BUILD_TEST) // Do not Print in Shipping or Test
	// Execute code here.
#endif

How can I exclude debug code in shipped build ?

This will cause compilation errors. Use #if UE_BUILD_DEBUG instead. The reason is that #ifdef returns true for #define UE_BUILD_DEBUG 0, since it is defined, just to the value zero. In general, at Epic we use #if !UE_BUILD_SHIPPING (not shipping).
