thanks for the comments.

As slin and me just said, the displacement map of the ground texture will be done accurately - with ZBrush. It's the best way to do this in the most accurate way. Actually the relief will be used for just a bit more realism of... well... relief, ya know?

As for the carpet: A shadow would help. All this will be done at a later time, because we are still checking and testing things out... nothing what you are see here is final - so please be patient with us

greetings
