Learn how the Boat Attack demo was created using the Universal Render Pipeline. These slides offer an in-depth look at the features used in the demo, including Shader Graph, Custom Render Passes, Camera Callback, and more.

7. What is Universal Render Pipeline (URP)?
7
Beautiful Graphics
Performance
Platform Reach
Extensibility

8. What is Universal Render Pipeline (URP)?
8
Continuation of Lightweight Render Pipeline
Shaders, scripts and assemblies updated automatically
Manual upgrade required if you are using UsePass or Shader.Find
Universal Render Pipeline is going to be supported in 2019.4 LTS

9. What’s new in 2019.3?

10. Forward Renderer
10
— Increased Light limits
– 8 lights per-object. Except GLES2 which is 4.
– 256 per-camera. except in mobile which is 32.
— Additional directional lights are now supported.

11. 2D Renderer
11
— Realtime shadows
— Post-processing support

12. Post-processing (v3)
12
— Built into URP

13. Post-processing (v3)
13
— Built into URP
– Color Grading mode HDR or LDR
– LUT size

14. Post-processing (v3)
14
— Volume Based

15. Post-processing (v3)
15
— Post-processing v3
– Anti-aliasing
– Depth of Field
– Motion Blur (Camera)
– Panini Projection
– Bloom
– Lens Distortion
– Chromatic Aberration
– Color Grading and Tonemapping
– Vignette
– Film Grain
– 8 bit dithering
– Custom effects are not yet supported

16. Post-processing (v3)
16

17. Shadergraph
17
— Artist friendly tooling

18. Shadergraph
18
— Shader precision nodes
— Shader keywords
— Custom function nodes
— 3D and 2D lit and unlit graphs

19. VFX Graph
19
— Compute Based
— Unlit support
— Lit support is coming soon

20. Improved camera settings
20
● Camera settings are now categorized
○ Projection
○ Rendering
○ Environment
○ Output

21. Improved lighting settings
21
● Colored light gizmos
● Depth feedback
● Inner Spot Angle
● Handle values in Scene
View

22. Quality
22
— Quality set in the Pipeline Asset.
— Explicit: You get what you ask
— No upgrading from Built-in to
Universal

23. Quality
23
— New Custom Render Pipeline field
— Allows pipeline asset per-quality
tier and platform
