You know what's crazy? The PS4 Pro is known to be loud even when cleaned, but throughout my entire playthrough until Platinum of the game, not once have I heard my console emitting any noise I'd usually hear when playing games such as God of War, Ratchet and Clank, and Days Gone. It _does_ make slight amount of noises during cutscenes but that's to be expected, but the gameplay experience itself is so silent it's quite jarring. I remember sometimes putting my ears next to me console to hear any noise but nope, nothing. Add the inexistent loading screens to the mix and the praise goes to Sucker Punch for pushing the console to its limit as efficiently (and quietly) as possible.

my first thought when i played the game was "how is this not super expensive to run?" they did a great job optimizing it unlike some other AAA developers. It shouldnt be something you congratulate since all games should be optimized. but its getting rare nowadays.

this is really interesting stuff, for something that you might hardly think about in game the developers put a lot of thought into it. correct me if I'm wrong but this type of work falls under the role of a technical artist, right? rather than purely the environment artist?

[@alexnoman1498]

70% of the screen ought to get a good deal of work/thought put into it :D

[@hexcrown2416]

Yes, technical artist, they would figure out what types of tools would be needed and create them and/or get other developers to create them, then the environmental artists would make use of the tools to actually create the environment.

[@herogamerbr12]

Some environmental artists have deep technical knowledge. It depends mainly on the project actually (for a huge game like this there will be more people working).

The facing to the camera reminds me of the old games that spin trees or character sprites to face you. Mainly thinking of racing games, but they are the games that tend to perform extremely well for their graphics.

[@diamondglitter205]

I admire their computational efforts. but the challenge is when the quality of realism increases, the required level of art grows simultaneously

[@PO1PLE]

That's why the textures are procedural, and why ue5 already comes with thousands of scanned in assets. It will literally cut the workload down back to what it was back in the late 360/ps3 era

[@MrVecheater]

Actually this takes away a lot of work for the devs so they can focus on more important artistic aspects The grass itself is still modifiable by hand if necessary

To make it easier to understand, you can change "frustum + distance culling" to the ordinary explanation of what it actually is - checks if objects are in the camera view at all, and not too far away. These are small things, but they add up for average user and make things harder to grasp. Nevertheless, a great video.

[@powergannon]

It’s amazing that multiple draw calls from using grass cards gets so expensive, that it is cheaper to render every single blade using geometry.

[@Dezomm]

Amazing. So many good ideas in here. I really, really want to see if I can reproduce this grass behaviour. Especially the LOD blending, not sure how to accomplish it but it seems like a great challenge.

[@Fabio-zc7bs]

Zelda's Grass was made in a similar way too. Polygonal grass looks like the future since GPUs are getting better and better to render Polygons but at the same tame, overdraw still a massive problem when using cards. Creating Procedural Mesh for foliage does not seem like a big trouble, but I guess It would be a pain to use it in Unreal, for example, since I don't think Foliage Tool would be usable, requiring us to do GPU instancing manually (Maybe I'm wrong, IDK). It looks like a lot of hard work.

[@Fabio-zc7bs]

Devs generally talk about this kind of find on GDC Talks. You will definitely see a lot of content on their Channel/Website. They don't go too deep on each technique since it would take weeks to tell each detail, but they take the main points and explaing their logic, show their experiences and their results. It's a good Channel to gamedevs, in general. The thing is, for Indies this may look a little bit "too technical". Sometime you'll feel lost in some concepts (Mainly if you only do only one area like 3D Art, for example).

kind out of topic but im once found a game with advanced grass setting distance, density, and scale. the most performance hungry is density. im max the distance value and keep the density low and make scale more a bit to fill the empty look space. its beautiful and it eat very less performance, almost same like the max setting. but all im see in most game the grass is not the problem what it make good but how it look good.
