I am using Telrunya by Nouschka Design in a scene, but the textures are coming out really bad.  I am rendering at about 4000 x 3349 because I am going to be painting in the hair of the subjects during post work.  I am using a focal length of 90. 

I am operating out of Daz Studio 3 Advanced on a Dell Inspiron 620, Windows 7, Intel Core 13-2100 CPU @ 3.10GHz processor, 8gb of RAM, and I believe an on board video card that is an AMD RADEON HD 6450.  I have tried to render this using both the 32 and 64gb program.  I am using the Daz specific, .dso file, for this.

I have included three snippets of the scene to show what I mean.  The textures are listed as 2500x2500 and 3000x3000, are those not big enough for an up close or large render?  Any input would be greatly appreciated.

I’ve looked at the textures themselves (and you can do so easily as well) and while each file is indeed 3000x3000 there are multiple parts covered by each file, usually 4 or 5, meaning you’re really only talking about 600x600 per surface.

E.g.,

So it’s not a setting issue, it’s just that the textures are best for a less intrusive camera angle?

Darn it.  Back to the drawing board.  Or at least back to looking for a background/room.

Thank you.
