For some reason when I import the P (world position pass) into Nuke, it imports directly onto the negative Z axis every time, no matter where in the scene the object is. No matter the scene, no matter the object.
I've tested this with Mental Ray Vray and Arnold and all three renderers put it in the right place in Nuke's 3D scene (lining up with the object in the camera view). \
Why isn't the World Point Position Pass transferring to Nuke while the alembic files export to the right location?
Thanks for the quick reply. That makes sense. I'm researching on the docs and forums but can't seem to find out how this is done.
How can you export the new P parameter from Vops to the mantra AOV (extra image plane)?
I assume P is being created from the material so each material would then have to transform P from camera space to world space and export that variable (somehow) back to the AOVs through a Parm node or something?)
Do you have to do it on a per object/per material basis or is there a global way for everything in the scene to do it?
I was going crazy with this and I didn't have time to rerender just to do a relight in Nuke, so I just placed the camera at the origin and swapped z in the position channels on the render.
