IBP is InjectionPose Builder from DAZ, it is $2 or I guess $1 now - from PC. It is Rob Whiz' creation. Although 'Recursive Batch' is not a phrase I had occasion to understand before, I means that the program will also automatically convert every file in a folder, if you have a batch to process. It coverted one of the V3 50 head shape folders into individual INJ/REM poses in about 5 min. The orginal had a master INJ and 50 pose files. This way - only the required morphs are injected for each face.
