A Hidden Benefit of RenderGraph in Unity 6 URP: Public Access to Core Render Resources

While exploring Unity 6’s URP, I noticed an interesting change: In the 2022.3.x versions, many internal render textures (like m_DepthTexture) could only be accessed via reflection, which was neither convenient nor safe. However, with the introduction of the RenderGraph architecture in Unity 6, these internal resources are now exposed through public APIs!

This means we can now access these core rendering resources in a much safer and more stable way, without relying on hacks or reflection. In my opinion, this is a great “side benefit” brought by RenderGraph, making custom rendering workflows more flexible and projects easier to maintain.

If you need to deeply customize your rendering pipeline, definitely take advantage of this improvement!
