This video continues the exploration of URP Render Graph samples, focusing on advanced data passing, compute shaders, and GBuffer management.

The Render Graph video series provides an introductory walkthrough of the Render Graph API in Unity’s Universal Render Pipeline (URP) using the Render Graph samples. Render Graph, introduced in Unity 6, is a programming interface designed to manage GPU resources and rendering passes efficiently, replacing the older scriptable render passes.

Part two of a series on Unity's Render Graph API in URP, walking through multiple code samples. Topics covered include: sharing textures between passes using frame data, using named output textures accessible in Shader Graph, running compute shaders via render features, rendering filtered geometry with renderer lists, customizing culling results, using unsafe passes for different-dimension blits, outputting to multiple render targets (MRT) in one pass, and accessing or promoting GBuffer textures to global scope for deferred rendering pipelines. Each sample highlights key API patterns and best practices for migrating to the Render Graph system.
