Hi everyone, is FMOD engine have way to log output to custom output or something like that? Because FMOD log version output only in to VS Debugger Output, and is not to comfortable when you don’t have access to VS. Or logging version of FMOD engine is supposed using only with debug build of game\game engine?

Hi,

You can indeed log to a custom output - [`Debug_Initialize`](https://www.fmod.com/docs/2.02/api/core-api-common.html#debug_initialize) allows you to specify a debug output to use with [`FMOD_DEBUG_MODE`](https://www.fmod.com/docs/2.02/api/core-api-common.html#fmod_debug_mode); either to TTY, to a file, or to a custom [callback](https://www.fmod.com/docs/2.02/api/core-api-common.html#fmod_debug_mode). If you have any further questions, feel free to ask!
