Lighting in Daz 3D and HDRI

[PropaJack]

I'm having a problem with some clothes in DAZ.
As you can see in the image, the shadow in this prisioner clothes is always strange, what kill the image.
The dog is strange too. There is a way to solve this and make the light not that strange or this clothe will always be like this?

Other doubt I have is the HDRI, that change "place" when the "camera" move. the three of the image moves depending the angle, so it's hard to mantain a consistence in the history... is there a way to solve this too?

If your problem is with the shadow in the clothes, i manage to make it better with other kinds of light, that don't have hard shadow, like emissive lights.
It's not ideal, because in lights in HDRI that doesn't help, but it helps... sometimes. not so much.
