Same scene, same camera move. Fog measured from the camera washes everything grey as the camera moves in. Fog measured from the figure's plane keeps the figure pure black and every layer's tone. In the shader it's one line. Unity 6 URP #screenshotsaturday #gamedev #techart

1 step vs 16 steps. Each step asks the moon's shadow map whether it can see that point, and blue-noise jitter plus a blur turn the stairs into smooth light. 0.14 ms on a laptop GTX 1650 Ti, Unity 6 URP. How many steps would you have guessed? #gamedev #techart #unity3d

The sails cut real moonlight on every frame. The light shafts are raymarched through the shadow map, with fog and a film print on top: 2.5 ms a frame at 1080p on a laptop GTX 1650 Ti. Unity 6 URP, code and a Windows build: github.com/matbcontrol/Nitrate #gamedev #techart #unity3d

Falling forever in Unity 6 URP: one 48 m tile of cubes drawn as ~320 instanced copies, outlines from a distance field, after Arthur Brussee's SIGGRAPH 2020 talk on Manifold Garden. Code: github.com/matbcontrol/InfiniteGarden #unity3d #gamedev #techart
