Rotohelper is a DazStudio script i created very quickly to help someone, it's not really user friendly

but after a few minutes of learning it does the job :)

There is no user interface, you must modify the code using a text editor like notepad or wordpad

( make a backup first )

the instructions are part of the script's code

// lets say the timeline is at frame 7

//

// launching this script will load the image

// c:\job001\bkgpics\pic7.bmp

//

// ( note that since padds[0]=0, then number 7 is not padded with zeros )

//

// then this image will be applied to the "Diffuse Color" channel

// of the material named "Default"

// of the node named "Plane"

//

// and

//

// the script will load the image

// c:\job001\frgpics\pic07.png

//

// note how number 7 is padded with 2 zeros, as specified by padds[1]=2

//

// then apply it to the "Diffuse Color" channel

// of the material named "Default"

// of the node named "Plane 2"

//

// on a Mac, the values of paths[] should look something like
