    Cannot upload vector to fragment shader in Stage3D


      I am trying to upload a vector to the shader but it's not working and I can found why.





      Here is the code:



          mov ft0.rgb, fc0.rgbb

          tex ft1, v1.rggg, fs0 <2d, linear, nomip, repeat>

          mov ft0.a, ft1.aaaa

          mov oc, ft0



      Where fc0 is the vector I am trying to upload:



      With this function I call before drawTriangles and present:



          Engine.context.setProgramConstantsFromVector(Context3DProgramType.FRAGMENT, 0, Vector.<Number>([value1, value2, value3]));



      I've debugged the scene with [Adobe Scout][1] and apparently fc0 has no value.



      If I substitue the last ft0 for ft1 it works since I am rendering only the texture.



      Any suggestions?
