Hasta La Motion!

Hi, i’m learning the relighting. So i need to feed the Normal and Position pass. I check and test to render out Normal pass from couple of 3d app. Some of them output the normal vector as relative direction to the camera. Some other output the normal vector as absoult XYZ world. Which one is correctly needed for relighting in Nuke ? For example houdini and modo render out differently. In houdini , the normal is translated as xyz (rgb) which is relative to the render camera, while modo translate the normal as absolute world-xyz position.

thanx

Hello everyone!

Does anyone have a link(s) to some free 3d stock footage that I can practice on? It can be anything from a multipass composite to some matchmoving exercises.
I found this site, which is exactly what Im looking for. In particular the t-rex chase.
