is there a way to create a y-up position pass.?

[FSGFX]

if i create a position pass with the sampler info texture i have the problem that i get it z-up...
but i need a y-up pass for the nuke PositionToPoint node...
my cam in nuke is also y-up...

any ideas...?

You'll have to swap the Y and Z components and negate one of them (not sure right away which one); this could be done with a shuffle node, I think.

Best regards,

ive tried shuffle everything in all directions... but i wont get the right direction...

edit: worked now...
you have to swap green and blue and invert blue...

thanks vlado without your int...
otherwise i havnt tried it a second time...
