[Nuke-users] from/minus in roto node

2014-04-18 Thread John Mangia
Wondering if one of the Foundry folks might be able to answer why there is a from/minus layer mode in the roto node when it ends up creating negative values (something you never want in an alpha). It's been like this forever and I'd rather have mask/stencil modes available. Coming from Shake

I have used roto in the past to work on data channels such as motion vectors, in which case negative values are quite important. It's more of an educational problem than a software feature problem I think, but I guess a clamp option might be a reasonable thing to
