Got it to work using both methods (Strap on and Genitalia Core)
Using Cock O Rama with Genesis 3 Centaurs
C-o-R works partially as an anterior (frontal) penis for Centaurs; allowing you to create stuff like John Varley's Titanides (from the book series Titan).
The easiest way to use C-o-R as this is to create a Centaur as you would normally in DAZ 3D, then:
*********************************************************************
Strap-on Method
Select Genesis 3 Male Centaur
Go into G 3 Male / Anatomy / !Cock O Rama Strapon
Select Cock O Rama Strapon Script and apply
That will create and fit a strapon to the Centaur at roughly the right place on the (Human) torso.
Create an All Purpose Cock via selecting it via script.
Go into Utility-Scripts and use All Purpose Cock Strapon Parentor (with Cock-O-Rama All Purpose Cock and Cock-O-Rama_Strapon_Male both selected) and use the popup dialog box.
Now you can adjust things.
Click the eye button next to Cock-O-Rama_Strapon_Male in the Scene List; that hides the strap-on harness.
Select Cock-O-Rama_Strapon_Male. Go into parameters and use
Cock Ring Move Foreward
Cock Ring Move Side-Side
Cock Ring Move Up-Down[/b]
to adjust where the cock is in relation to the centaur's frontal body.
You can also try adjusting the X-Y-Z Translate/Rotate parameters for Cock-O-Rama All Purpose Cock to get a better fit to the centaur frontal horse mesh.
*************************************************
Genatilia Core Method
Select Genesis 3 Male Centaur
Go into G 3 Male / Anatomy / !Cock O Genitalia Core
Select Cock O Rama Genatilia Core Script and apply
That will create and fit a Genatilia Core to the Centaur at roughly the right place on the (Human) torso.
It will be hidden mostly by the horse body. You need to bring it out from the horse mesh.
Drill down into Cock-O-Rama Genitalia Core through:
Hip
Pelvis
and select Genitalia
Use
Move Side-Side
Move Up-Down
Move Front-Back
Bend
Side-Side
Twist[/b]
To get the Genitalia Core positioned right outside the horse body mesh.
This is where it gets tricky in texturing; because there's something called Centaur Shell that actually interacts with the Genesis 3 figure.
To make everything (Genesis 3 Figure, Genesis 3 Centaur, Easy Rider Genitalia [if used]) work together nicely; you have to add the Genitalia Core Materials by hand:
Select Centaur Shell; and go into Surfaces tab.
There should be something in the list named
G3MGenitalia_Genitalia
Select it; and then go into
Cock-O-Rama
Genitalia Core
Copy Materials
Monster MATs (lray)
select something brown/darkish like Cock-O-Rama Shell Demon Red Dark Red Socket
This is the only way to do it.
DO NOT try to create a geo-shell for Cock-O-Rama with Centaurs, because it causes odd interactions like ruining the blending for stuff like Easy Rider Genitalia on the Centaur Body.
