Been searching for this for my lifetime. Every other tutorials are like Go to Post process Volume and go to "Details" and all. Thank You so much

Matt, you really use cast to nodes in your tutorials too much, it is a very unoptimized way of having blueprints communicate, having a lot of them can cause significant frame drops, I don't know if you know about BP interfaces, but they would definitely be a lot better in every scenario, in the case of this video, you'd use the call function (message) version in the player blueprint to trigger the event version of the function in the level blueprint, no call to nodes and saves you binding events on begin play.

Nice, can you also have two post process volumes and switch priorities or blend weight with the 1 key. Will it be more performant or not?

I did this keeping the baked lights separate. Create a level streaming for the static baked lights and one copy of it for Lumen and movable lights. I switch between these 2 pressing a key. I also made sure that it wont fire if the pc or mobile is not compatible. I have the best of both worlds. Would love to give you more details about it, if you already didn`t find a better solution.

Would love to get some more informations on it. It is exactly what I want to accomplish with my project. Some guidance would be awesome. Thanks

Hi Matt, thanks for all the really helpful vids. Just wondering, do you have any videos that covers how to get an ai to crawl through an obstacle to get to the player? I'm trying to make a window where if the zombie see's you, it walks up to the window, breaks it, and then crawls through to get to you. I have a good idea on how to make the logic for the behavior tree just wondering if you have anything that already covers this?

Thank you for this Matt. One of the things I'm not clear on with lighting, that's mixing baked, and dynamic lighting, considered relative to Lumen. Like this, Outdoor scene, Lumen wanted because of it looks great outdoors over dynamic, and does one even ever bake outdoor lighting? There's a cave, there we want baked lighting for performance-sake. Just put a Lightmass volume around the cave, leave the outdoor lighting as normal dynamic or Lumen? Speaking of performance, I have an outdoor level I'm testing things. It's a Procedural Landscape (I think it was a monthly freebee asset). It seems I'm getting better fps with Lumen enabled over straight Dynamic... not quite sure why. In other test levels it's the total opposite, Lumen is more demanding - which is what's expected.

Depends on your hardware and meshes being rendered and calculated for shadows. Also if you are using dx11 vs dx12

i would like to know how epic games have created the assets that u see in the very first seconds of your video. i know they use zbrush and all those are nanite, but are there any rules on asset creation for nanite? which influence has this on your scene size on your harddisk ? etc etc

Finally, a realistic take! Lumen is not working as intended and should not be forced on in a game. Adding this to my main menu as part of the user settings. Thank you.
