You can either Emit from the whole and delete the ones that aren't pointing in the right direction, (based on comparing the normal angle to your preferred vector)
Or create a weightmap on the object and use ICE to set the values based upon the normal angle and use the weightmap in the Emit node. (This wont work on low poly meshes for obvious reasons) Or make a duplicate of the surface, and use ICE to delete Polys that aren't pointing in the right direction, then emit from the resulting object. Number 1 is the easiest to set up.

I have looked through the sample scenes but could not find something that does this. I want to emit particles from surfaces of an object that faces in a particular direction, either a custom vector or fom polygons facing a null. How can I do this? Thanks.
