I have a mix of 2D and 3D sounds and loop through them in the update call. Can I call `set3DAttributes()` on a 2D sound and will that simply be ignored? Or should I check with `Studio::EventDescription::is3D()` first? The documentation doesn’t seem to be clear on this

Hi,

The 3D attributes will be applied to the 2D event but it wont have an effect on the audio. Most FMOD function calls return an [FMOD Engine | Core API Reference - FMOD\_RESULT](https://fmod.com/docs/2.02/api/core-api-common.html#fmod_result) which can be useful to debug functions.

I will make a task to add a note to the docs the make this more clear. Thank you for bringing this to our attention.
