'ComputeShader 不包含 SetMatrix 的定义'

Question

Currently I am trying to follow this tutorial on ray tracing using compute shaders . I am trying to set the matrices for the compute shader using ComputeShader.SetMatrix(string name, Matrix4x4 val) , or in my case specifically, RayTracingShader.SetMatrix("_CameraToWorld", _camera.cameraToWorldMatrix); .

However, I get the error 'ComputeShader does not contain a definition for SetMatrix' , even though this Unity page clearly indicates that it should be possible. I am also unable to find anyone on Google with similar problems. I have just now updated Unity to version 5.5.4p4 Personal. Before that it didn't work either.

Any help fixing this would be greatly appreciated.

Answer 1

Unity 5.5 does not define ComputeShader.SetMatrix .

You need to update to a version of Unity where ComputeShader.SetMatrix exists.

It seems like it first arrived in 2017.3
