ABOUT
This is a partial porting of Relight plugin suite for Fusion, also written by yours truly.
These plugins allow fast 'true 3D' relighting of rendered sequences, given a depth channel and the 3D camera. This means the lighting will take into account the actual position of the surfaces and not only their normals. And this means, in turn, that you can relight using a spot light with quadratic decay, for example.
Now, here's why 'true 3D' is NOT true 3D (and you can't kiss mental ray goodbye - yet):
  • NO SHADOWS
  • no raytracing - no reflections, no refractions, no nothing
  • no volumes of any kind
Still, it is not completely useless. A clear example is with 'magic particles' done in compositing. They're magic, so they're not supposed to cast shadows, are they?

INSTALLATION
Put the files in %NukeDir%pluginsuser


QUICK START
Have a node with depth and normals and a matching camera. Create a rl3D node, select depth and normal channels, and depth type (eg -1/z for Maya). Create output layers for diffuse, specular and ambient components. Connect the camera. Create rlLights as needed and connect these also. Create rlMaterials as needed and put them AFTER the the rl3D node, they just ADD the actual lighting according to the material properties you define and the relevant mask.


DETAILED INSTRUCTIONS
Skipped, waiting for a source of inspiration ;)
