Render out a World Position pass

[Maximus]

Hey, i was wondering if anyone knows how to render out this pass so called World Position
It should look like the leftmost image.



Tryin to dig into Mental Ray nodes and modes but it doesnt come into mind how i could output such pass, any help would be appreciated.

Thanks, Max

It's the "vector state" node, and "intersection point" in the properties (some scaling would be needed not to go over 1)

make sure when you render a pworld pass to have set your output to exr 32 bits.
You want here precision as much as possible.

thanks. u'r right, but the "World space" don't look like a picture above.

You Know why?

hey
that's what i came up with.

my question is about the suggested rescale. if i don't rescale it looks like your eye space example.
if i set the rescale input values to -5 to 5 i get something more looking like the world space example.

but why -5 and 5? i don't know, i just put those numbers in, but i'm shure we could calculate those... (?)

If you want the XYZ positions in the output, why do you rescale the color? Aren't you changing the XYZ coords stored in the RGB? If you load the rendered EXR into the FX Tree viewer and mouse over, you'll see the actual XYZ coordinates that are stored in RGB.
