Question How to deal with array properties with SRP Batcher

I am writing a custom shader under URP with SRP Batcher enabled.

I want to declare a vector array property, say "_Colors":

Code (CSharp):

1. half4 _Colors[8];

and in order to let this shader to be SRP Batcher compatible:

Code (CSharp):

1. CBUFFER_START(UnityPerMaterial)
2.     half4 _Colors[8];
3. CBUFFER_END

But now I have no idea to declare it in

Properties

block, because there is no

Array

type similar to

Vector

or

Color

.

Besides, I have tried some ways and found something interesting:
1. If a uniform variable in

UnityPerMaterial

CBuffer has a

Array

type, and a property declared in

Properties

block with same name, whatever its type is, SRP Batcher will feel satisfied. (tested by attachmented TestSRPBatcherCompatibilityWithArrayVariable.shader)
2. If a uniform variable in

UnityPerMaterial

CBuffer has a

Matrix

type, and no property declared in

Properties

block with same name, SRP Batcher will feel satisfied. (tested by attachmented TestSRPBatcherCompatibilityWithArrayVariable.shader)
All above are so confused to me.
(All my attachmented shaders are tested under Unity 2019.4.29f1 with URP 7.4.1, on a Windows PC.)

 

I cannot edit this thread. And I missed a shader attachment. And I didn't find out how to delete this thread, so I posted a new one. (Maybe the administrator could help me to delete or lowest this thread?)
