does it matter if we have to export textures? it doesnt take so much time to upload every texture.
it woudl be great if i can animate in poser and then send this to a different render.

I think he was talking about the materials as a whole, not just textures. Like trying to find a way to more or less translate Poser nodes into other render engine nodes.
The current Poser exporters only transfer materials insofar as textures and simple shaders. For example, in Maya, they show up as simple Maya nodes with Phong shading and if you want to use the far more advanced Mental Ray nodes with the Mental Ray render engine, you have to manually set it all up.  Same with Lightwave, and I would assume the same goes for 3ds Max.

It would of course also depend on how open the SDK was for other software, and determine if it were possible at all or not.
