This position toolkit is based on Deep2VP to create and work in 2D compositing instead of Deep. The toolset has PosMatte, PosPattern and PosProjection, the function and workflow is the same as DVPMatte, DVPattern and DVProjection in Deep2VP.
Requirements:
12.0, 11.3, 11.2, 11.1, 11.0, 10.5, 10.0 or later

This position toolkit is based on Deep2VP to create and work in 2D compositing instead of Deep. The toolset has PosMatte, PosPattern and PosProjection, the function and workflow is the same as DVPMatte, DVPattern and DVProjection in Deep2VP.

Input of all these nodes must contain world space position data and alpha. If you need to convert position camera space, can use PNZ Suite to do the job.

 

PosMatte

creates 2.5D matte from position data. In this node, it has 3 matte shape and 5 different ways to place the matte.

 

PosPattern

can create 7 different patterns through position data.

 

PosProjection

can do camera projection with position data. This node requires a camera, texture is optional (it is because it also can output UV maps). Camera can be a custom one, but usually for CG patch fix will use the shot camera to avoid line up perspective manually. It's because the node will calculate FOV of the camera for projection.

good job
its possible to use custom geo as matte geo?

yes, it's possible.
This comes up in my mind to use

DeepFromPosition
https://www.nukepedia.com/gizmos/deep/deepfromposition

and then

DeepBoolean
https://www.nukepedia.com/gizmos/deep/deepboolean

to matte it with custom geo. After that DeepToImage back to 2D.

Let me see if any room to optimize the setup, but you can use above setup to get it work at the moment.

Hi,
Can you explain the process of how u create poss matte
especially geo masking

Hi Sangeeth, sorry for the late reply. In production, the position pass usually provided by CG render. In nuke itself, it can be produced by ScanlineRender node. You can check out Nuke's doc here : (under surface points)

https://learn.foundry.com/nuke/content/reference_guide/3d_nodes/scanlinerender.html

for how this tool work (such as create matte). You can check out this video.

Hi Mark really great tools, could save time on last minute tweaks.

I tried the PosProjection_M J and it works great on static objects, so was wondering how would it be possible to project a texture on the moving or animated object.

I guess there is some way to convert world position to the local and in that case it would work, would be great to have that option in the tool and this would become one of my must have tools in nuke ;)

Amazing tool! There is an issue with images that have a par other than 1 in the PosProjection. I think it happens at stmap creation step. I hope it will be fixed. Thanks again for sharing!
