I don't remember which show, ISC or Q&A perhaps, mentioned this, but the devs talked about ray tracing being used for proper audio directions. For example, if someone walks to the other side of the wall, you'll hear the sound come from the window or door instead of through the wall. Can you give us an update on this tech?
TL;DRGraham Philipson says he is actively working, as his top priority, on room-system traversal that will underpin audio propagation and help AI, but it has a long way to go and he gives no release timing.
I certainly can, because I'm currently working on it. So right now I'm working on some additions to the room system in the game. Those additions are not specific to audio. They're going to underpin how this audio propagation is going to work, but they're going to be used by other systems too. The AI team's interested in what I'm doing, and there are other systems that would definitely benefit from this thing. But I'm in the process of making it possible to efficiently traverse through our room system. And by efficiently, I mean I'm talking thousands of queries per game frame, so that we can make sure all the audio knows which path it should be taking. Then also we can help to inform the direction that AI should be taking to find a particular room or place. So it's got a long way to go. I'm not going to say anything about when it's going to finally make it into the game, but I am actively working on it, and it is my number one priority right now. So obviously your priorities shift all the time, but yeah, this is very much in progress. Personally, I think this is one of the biggest things I want to see in the game from my own perspective. So yeah, I'm really pushing hard to get this working.
