OptiTex hardly supports common 3D formats at all, but does DXF. Poser imports DXF.

Poser can't handle DS lights, cameras, shaders and the Mixamo and aniMate features, so why should it handle DS dynamics?

This from the DAZ forum:

Here are some commonly asked questions and their answers regarding the new dynamic clothing plugin and content for DAZ Studio: 

Q: Can I create my own dynamic clothing? 

A: No, not currently. A separate dynamic clothing creation tool is required for you to do this. This tool is not yet available, as it is still in development. DAZ 3D has been able to create clothing only with help of the OptiTex pattern creation team and their internal tools. The release of a content creation tool is of critical importance to DAZ 3D, and we are doing everything we can to help expedite the release of this tool to our market. Meanwhile, new clothing items will continue to be released as they are developed by outside resources.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
