Feedback Please expose more parameters in ScriptableRenderContext.DrawSkyBox

It would be very helpful to be able to subvert behaviour of the black-box DrawSkyBox method, which currently only takes the Camera as a parameter for setting up view matrices.

A couple suggestions here would be to allow for setting RenderStateBlock, and the Mesh itself.

Currently in our custom SRP I can do the later:

Code (CSharp):

1. public bool OverrideSkyboxPass(ScriptableRenderContext context, Camera camera)
2. {
3.     if (camera.clearFlags != CameraClearFlags.Skybox
4.         || _skyboxMode == SkyboxMode.Default
5.         || camera.cameraType==CameraType.Preview)
6.         return false;
7.  
8.     CommandBuffer cmd = CommandBufferPool.Get("Draw Skybox");
9.     {
10.         cmd.Clear();
11.         context.ExecuteCommandBuffer(cmd);
12.        
13.         cmd.DrawMesh(
14.             skyboxMesh,
15.             Matrix4x4.TRS(
16.                 camera.transform.position,
17.                 Quaternion.identity,
18.                 Vector3.one*SKYBOX_SCALE),
19.             RenderSettings.skybox);
20.         context.ExecuteCommandBuffer(cmd);
21.     }
22.     CommandBufferPool.Release(cmd);
23.    
24.     return true;
25. }

But here I cannot subvert the RenderStateBlock and must resolve things like Stencil in the Shader directly, which is inconvenient and error-prone as it requires our Content Creators to set data in several locations.

Thanks,
