FX Composer is really a great tool to create shaders.

But I do not find a way to bind the camera position to the shader register. I have checked SAS and other documentations and check the internet and did not find a way to make it work.

I have tried (PerspectiveCamera1 is the name of the Perspective camera that I have added):

float3 Camera1 : POSITION <
string Object = "Camera";
>;

float3 Camera2 : POSITION <
string Object = "PerspectiveCamera1";
>;

float3 Camera3 : CAMERAPOSITION;

float3 Camera4 : CAMERAPOSITION <
string Object = "Camera";
>;

float3 Camera5 : CAMERAPOSITION <
string Object = "PerspectiveCamera1";
>;

float3 Camera6 : CAMERAPOSITION <
string Object = "PerspectiveCamera1";
>;

float3 Camera7 : POSITION <
string Object = "Node7";
>;

I also tried to use VIEWINVERSE but could not get just its transform part into float3.


So many shaders are using CameraPosition or EyePosition so there should be a way to do the binding. Could you please tell me how to do this. (By the way binding light position works great).
