public void SetRayTracingFloatParams(Experimental.Rendering.RayTracingShader rayTracingShader, string name, params float[] values);
public void SetRayTracingFloatParams(Experimental.Rendering.RayTracingShader rayTracingShader, int nameID, params float[] values);

Parameters

rayTracingShader RayTracingShader to set parameter for.
name Name of the variable in shader code.
nameID Property name ID. Use Shader.PropertyToID to get this ID.
values Values to set.

Description

Adds a command to set multiple consecutive float parameters on a RayTracingShader.

The values specified as argument can be used only by the shaders defined inside the .raytrace file associated with the RayTracingShader. If the values needs to be visible in all ray tracing shader types (closesthit, anyhit, miss, etc.) then CommandBuffer.SetGlobalFloatArray or Shader.SetGlobalFloatArray must be used.

This function can be used to set float vector, float array or float vector array values. For example, float4 myArray[4] in the ray tracing shader can be filled by passing 16 floats.
