Hasta La Motion!

I have watched the dvd from digitaltutors about 2.5D relighting in nuke

I have tried to redo it on a simple scene and I have some problems

the edges of the objects are not cleans, there is a little outline around the objects.

in the dvd, the instructor said to render pointworld pass and normal pass aliased and apply 2 matrix afterwards in nuke.

i did that too but it seems that doesn’t work for me.

I’ve also tried to render with antialiasing and no matrix but it doesn’t work neither.

is anybody have an idea of what I can do to fix the edges

here is the script if you guys want to check
