never understood what does or are, external binary morph targets ?

The morph data for the figure/prop/scene is put in a seperate file in binary format instead of being in the same file in text.

A lot of programs that import Poser content don't read them, and they have been troublesome for various reasons (some of which have been fixed by newer version and SRs).
It boils down to Poser being more tolerant of certain mistakes in files when they are text.

So the morphs are stored in the pmd file which must have the same name as the .cr2 file?

And also the .cr2 needs to have empty delta for the pmd morphs?

Not always, the PMD file is referenced by whatever file uses it by a path, so it is possible to change the name and edit the referring path.
Also CR2, PP2, and PZ2 files are capable of referencing several PMD files if edited.

Don't really know, I suspect that one set of data will be used for any morph, but without experimenting to find out which, I'd guess that the PMD is probably read after the text data and that the last PMD read will be the one that defines the data for a given morph.

thanks now i have a better understanding

if PMD files could be read for figures that don't have empty delta files it would be a great solution instead of -inj poses...
Or at least an alternative?

Maybee if there where some add ons to take advantage of it and also the option if a figure uses PMD or not... (if I understand correct if you turn it on everytime you save a figure a PMD file is saved also?)

However I have heard so many times that they make poser act strange that I have deactivated them from the start...

They already work like that.

The "Use external binary morph targets" option only controls whether PMD files are created when something is saved, it has no bearing on them being read when referenced by a file, i.e. PMD files are always read, but you have a choice as to whether they're created.

oh! so if you have Use external binary morph targets ON you get an option whenever you save a file or you have to set it OFF/ON from preferences?
