GPU Driven effects // Powerpoint slides

The Last of Us Part II introduced more detailed interactions between effects and the rest of the world. In addition, the effects were GPU driven, making them more efficient and allowing for bigger particle numbers. The effects required much less manual placement from the artists and utilized world information for spawning, and could attach to and simulate on geometry efficiently, following gravity and surface properties on animating geometry.


Low level optimisations // Powerpoint slides

The majority of the world of The Last of Us Part II contains alpha geometry which has poor rendering pipeline performance and full-screen expensive shaders with heavy resource usage. This required us to use plenty of hacks and tricks to push the hardware to its limits and make sure we don’t have to needlessly compromise on the visual fidelity of the game. This talk mainly focuses on case studies from the actual game highlighting the most expensive parts of our game’s frame and how we were able to come up with solutions to these performance hurdles.


Volumetric effects // Powerpoint slides

This required us to create a new volumetric system that would support different fog environments and seamlessly blend with, and tie together, the rest of the world. We have developed a new volumetric fog system that is based on a view space frustum voxel grid (froxel grid) that allows us to properly composite with the rest of the world. However, such a system also comes with a lot of production challenges


Technical Art // Powerpoint slides

Most of the game would be ambiently lit which is a hard look to achieve. The game would be full of glass, rain, and lots of other tricky surfaces with a greater variety of environments than we’ve ever attempted. Early rendering tests of our characters showed just how far we had to go. To achieve all of this, we had to not only upgrade our tech, but also how our tech art team worked.


Lighting Tech // Powerpoint slides

Since the majority of the world of The Last of Us Part II has overcast lighting conditions, ambient lighting was a crucial component of our rendering system. Developing a game that is mainly ambient lit is already a challenge on its own, but we also had to deal with limited amount of processing power and memory on our target platform, PlayStation 4.

great! Thanks definitely watching it as soon as I find enough time.

BTW here is an INSANE read on the subject for anyone interested
