**bagginsbill**: this is the resolution I get with a 16-bit height map at 4096x4096. This is again with a sine function applied to the height value. Unfortunately, it seems to me that with this level of detail, you won't get a sharp edge for a stocking no matter how you write the shader. For anything that doesn't require sharp edges in textures, the height map approach might be quite useful, though.

The next potential step would be to go to 8192x8192, cut out just the bits we are interested in and place them on one or more 4096x4096 map. I imagine the scale and offset parameters of the image map node could be used in connection with such a map.

I'll post the new height map to the developers site, so you can play with it if you want. I might be able to do a 8192x8192 overnight if you're interested.

PS: I'm not sure I understand what you're trying to say re V4's mapping. Could you post a render that show's what you mean?
