bill recommended filterforge, bill said objects with "generic UVmapping" are easier to texture in poser, and IIRC bill said he rarely used tiling/seamless textures on his furniture items.  maybe those are clues.  e.g. buy filterforge or other wood generator, find out how to map objects with "generic UVmapping", and then slap those filterforge things on your furniture.   or tell your freebie users to buy bill's textures/items.

I reckon it may seem unfair to have to spend cash to distribute freebies, but it can be expensive.
