currently I am using Nuke to create a point cloud from a world position pass / P pass, and after that exporting the alembic to houdini to create a mesh from the point cloud. I would like to avoid using nuke, and rebuild the data directly in houdini. I know it must be easy peezy but really have no idea how to do it after a lot of trying and reading.
How can I recreate Nuke's PositionToPoints node in houdini, so I can rebuild the point cloud from the P aov of my exr, hopefully by combining multiple frames. Thanks for your help!!!
A user on odforce has posted a great answer, here it is:
“you should be able to just use
dense grid (you can switch to only points if you want) -> uv texture -> attrib from map (pick your image, Texture Channel: P (or whatever your AOV is called), Export Attribute: P)”
