This is what misaouin is talking about. These are the directions in the Optitex HelpWiki for integrating the Optitex model to dynamics in Daz:
In order to work with Daz, you will need to purchase the Daz Software with an Animation option.
Inquire on the proper plugin in Daz that is able to work with OptiTex.
Note that additional information and training are subject to billed charges, since OptiTex does not support external software.
All necessary information should be found within DAZ tutorials
1.Make a pose for a Daz figure in Daz 3D
1.Export the figure as a mod.file
2.Make pz.2 file to fix the pose for Daz figure
3.Import figure (mod.file) into OptiTex
4.Create your pattern in OptiTex 3D
1.Make clt file without textures
5.Load clt file into Daz
1.Export clt.file as an obj file
6.Load your figure in Daz
1.Use pz.2 file to ad the pose to your figure
7.Autorig your clt in Daz
8.Save the clt file as a scene in Daz
9.Bring in the obj file into UvMapper to generate a Texture UV map
10.Make your textures and bump maps in Photoshop
1.Bring them into Daz
2.Ad them to the clt
3.Save them as material preset
There are no options in the Daz menu to import or export .mod or .ctl files, even in the Dynamics plugin so there is probably another special piece needed from Daz in order to work with those file extensions.
