Subject: Re: [Nuke-users] Re: difference between uv project and project 3d
Hey Ari,
Here's the plugin I mentioned before.
http://www.nukepedia.com/gizmos/plugins/3d/stickyproject/
There's only compiled versions for Nuke 6.3 (MacOS and Linux64), but I've
uploaded the source code as well, so someone else can compile it for Windows if
needed
Hope it proves useful.
Cheers,
Ivan
