I dont know enough about DS to say for sure, but I cant see how the textures would need to made differently.  Especially for something simple like cloth.  recreating the shaders is one thing, but I would expect the lions share of colour, bump, displacement and specular maps would be the same.  Perhaps DS may require you to bake in certain things if its shader system cant replicate the same effects as poser or vice versa... I would hope that would be the exception rather than the rule though...

like I said though, I dont know that much about DS yet

 

Quote - Weight mapping doesnt really make things easier.

Since the weight mapping is still different in each program, they will likely need to be made seperately as well.

The ways of applying morphs are different

The shader set-up is different so textures have to be made independantly

Sp they really are completely seperate animals when it comes to making content.
