The Clear method in the RenderAttributes class is used to remove all render attributes that have been set. This method is useful when you want to reset the render attributes to their default state, ensuring that no previous settings interfere with new configurations.
To use the Clear method, simply call it on an instance of the RenderAttributes class. This will clear all the attributes that have been set on that instance.
RenderAttributes renderAttributes = new RenderAttributes();
// Set some attributes
renderAttributes.Set("Color", new Vector3(1.0f, 0.0f, 0.0f));
renderAttributes.Set("Opacity", 0.5f);
// Clear all attributes
renderAttributes.Clear();
// At this point, all previously set attributes are removed.
