** I`m looking for any thread or tutorial telling the basics how to create real poser content on my own. Means how to convert the objects into .ps2 files with all features like morphs and textures.Quite like the professional stuff sold here.

Hey,

You might start with these, if you're interested in making clothing.  You can alter the packs and use them to make commercial items...and freebies, if you get Randy's permission.  Whatever you decide, you need a modeling program (there are free ones, like Blender) to alter or make geometry.  Then you convert it to a figure, prop, or pose file.  For making figures with cr2s, (such as clothing), I REALLY recommend PhilC's obj to cr2 plug in for Poser -- although Randy's development pack comes with bone rigs.  He even provides a tutorial, showing you how to turn your altered geometry into conforming clothing.

Edit:  Excuse me...SOME of the development packs in Randy's store can be used for freebies if you get permission.  I'm not sure about all of them. 

I love me some Modo!  :-)
