I've got the nvidia plugin for photoshop for creating my own textures. It works...gets the job done, but it isn't really an ideal solution. it's a third party add-on to a secondary piece of software from Keyshot. I don't know if this is total pie-in-the-sky thinking here, but it would be absolutely fantastic if there were a built in normal mapper in Keyshot. Not an image editor or anything, just a normal mapper.
Now watch me go off and find that Adobe has started including a normal mapper in CS5. ::)
Or you just use a jpeg which gets the job done ... certainly, normal maps can give better details. We will take a look.
