This is typically done through sound attenuation; you can define a curve that dictates how the sound falls off over distance.

If sounds are spawning at 0, but not when there's a min color point number, it sounds like this might be a problem with the color point detection. This could be a number of things, such as the spatial hash, or more likely, it's that the locations are not being added to the subsystem as world-space, but rather relative. If you are still struggling to get it working after trying lots of approaches, it might be best to start over and add just one world location manually to the subsystem's color point collection, such as (500,0,0) in a blank level, and see if the subsystem spawns a sound there with a min color point number of 1 (also make sure your min spawn distances are set to 0 while you test this).

@@gamedesra thank you for replying, In an empty scene, with a location of 500,0,0, if I set the point number to 1, no sound spawns. Do you have a discord? maybe you'd see something wrong with a screen capture?

@@arthiyaxn Hi again. I'm afraid I don't have time to help people on a case by case basis at the moment, however, I spent a few minutes this morning on a demo project that you can find here (UE 5.3.2): drive.google.com/file/d/1LnlQKUfmSZZn9v7_MDKhblT4oT3frMNj/view?usp=sharing This contains one palette and one color set up to spawn at 1 min color point number, which might help you diagnose what's wrong with your own project. Do remember that the less points you have, the less likely your sound is to spawn unless you adjust your spatial hash. The necessary code is contained within the third person character blueprint and the level blueprint. I hope this helps!

@@gamedesra Hi, thank you very much! It's going to take me a while to find out where the error came from, but I think I can do it.

Hello, this is a custom trace channel defined in the project settings, it does not exist in the engine by default. While you can use the visibility channel, there may be certain objects that you don't want to be blocking the trace, so it's sometimes better to make a custom channel as I have. I hope this helps!

Hi there, sorry for not clarifying this. Break the input of the soundscape color point collection structure variable and this will give you an array input (the contents of the collection). Hope this helps!

@@gamedesra Thank you for the fast reply! I didn't realise you could split pins on set/get nodes. This will be very handy

A couple of things come to mind. When getting the instance transform of the foliage instance static mesh component make sure to tick "world space". If you need it in local space for whatever reason, then you can always use transform location to convert back to world. Let me know if this solves the problem!

@@gamedesra Thank you for replying! I tried few ways, so i found that the problem is color point problem not a vector array. because I tried this trace method in another way which is not a soundscape system, so i checked all the foliage vectors stored in vector array variable.

@@gamedesra can i ask one thing at last? if i add array vectors to colorpoint collection with colorpoint and then run add colorpoint collection node, are audios going to spawn at vector locations?

@@joon1809 ​Should do. If you have any problems then make sure to check: - Your hash sizes. - That your colors have your color points defined in the advanced spawn behaviour. - Your colors are present in your palette, and the palette is applied to the project. - If you are using states, make sure that this has been set as well. - As mentioned at the end of the video, you might encounter issues with negative Z world height for colors with clamped height, just something to keep in mind.

@@gamedesra Thank you so much!!👍

Hi Mason, thanks for the comment. I have updated this video with a link to the project zip in the description for free. Let me know if you have any problems!

​@@gamedesra Amazing! Thank you so much for sharing your knowledge.

Thank you for the comment! You're 100% right to want to avoid traces, there's definitely a more optimized way to deal with the data. Wishing you the best with your project!

I have a few upcoming videos planned, but I can certainly note it down for a future upload!

Definitely don't stop them coming@@gamedesra this is so much cool stuff newbies like myself can learn about in my early days as the Sound Designer (+ implementer) job :)

Are you using physical materials to detect surface changes?

Hello, thanks for the comment. Yes, I made this environment myself mainly for presentation purposes; I have been using it less and less recently, as it takes longer to load each time I add to it. If you want to set up some sort of testing environment, I would suggest using different maps for things such as reverb, footsteps, splines, and so on. Just add as you go. A custom character might be good to practice different sounds as the player walks beside footsteps, such as equipment. Hope this helps!

@@gamedesra thx！！！a lot of help！

Hello. These are retrieved from a struct variable on a save SaveGame Object when the widget is constructed. Hope this helps.

Hello. If this was a group of crows I’d likely use the colour point system, because the player would not be able to identity if the spatialisation is slightly off. For static individuals like the crow in the video however, I just handled it manually. I hope this answers your question.

@@gamedesra It does, thanks. I figured you handled it manually since the sfx emitted at the crow location, but wanted to ask in case you had come up with a way to retarget audio from a random location in the color point spatial hash grid to a specific actor if it happens to be in the area. Thanks for answering, and impressive work!

@@homerosanchez8481 Perhaps that’s an idea for a future video. I’ll be starting a small C++ series soon so I may tweak a few things in soundscape.

Thank you, it means a lot!

I have not looked into this aspect too much, but I believe platform-specific settings should apply when you package your game for the respective platform.

@@gamedesra The documentation talks about potentially creating like Android_Low or Windows_Low subplatforms but I couldn't find how you would load them, at least not for UE because there was some C# Unity code I found

I have not had a chance to check out R6 content yet, maybe that is something for the future. In the conclusion I mentioned CSGO and physical materials, which is something I want to explore in another system. Perhaps a later video on this will also include the Wwise portal system with a spatial volume to work alongside it.
