Hi, I would really like to texture objects with the following:
The only problem is lighting. Incoming is a vec3 pointing from the pixel to the camera, but I need light to see it. If I plug it into an emission node I can see it but then it will light itself and mess with the “incoming” value.
Ideally this is the kinda thing I’d do in Blender Internal since you can just have it essentially unshaded, but Blender Internal does not have this ‘incoming’ value.
Is there anything I can do to see it?
