URP and GPU instancing & MPB

Tested with: 2020.1.0b16.4138 + URP 9.0.0-preview.38, Windows DX11

Objects with same material & same property values

SRP batcher ON
material GPU instancing OFF
SRP batched
SRP batcher ON
material GPU instancing ON
SRP batched
(because if SRP batcher is ON, gpu instancing will be ignored)
SRP batcher OFF
material GPU instancing ON
GPU instanced

Objects with different material & different property values

SRP batcher ON
material GPU instancing OFF
SRP batched
SRP batcher ON
material GPU instancing ON
SRP batched
(because if SRP batcher is ON, gpu instancing will be ignored)
SRP batcher OFF
material GPU instancing ON
Not batched nor instanced
(expected because they are different materials)

Objects with same material & different property values set by MaterialPropertyBlock

SRP batcher ON
material GPU instancing OFF
Not batched nor instanced
(because MPB values are not same)
SRP batcher ON
material GPU instancing ON
Not batched nor instanced
(same as above)
SRP batcher OFF
material GPU instancing ON
Not batched nor instanced
(because properties are non-instanced)

According to Unity Documentation about GPU instancing, user can use MaterialProperyBlock to have different material properties for each instances.
Apparently the test showed that this is not true anymore in Universal Render Pipeline.


Reason:

URP shader properties are all wrapped by SRP batcher macros “CBUFFER_START(UnityPerMaterial)”.
GPU instancing need to use this macro “UNITY_INSTANCING_BUFFER_START(MyProps)”

3D scene need Linear but UI need Gamma

Looking for a way to make only the UI matches to what is designed in Photoshop? Don’t want artists to change any workflow because you are in the middle of development? Try this.
