Bump Map --> Normal Map?

Besides the nVidia plug-in (which doesn't work), is there a way to turn a bump map into a normal map, as in an alternative plug-in for photoshop, or anything of the sort?

The nVidia plugin works great, I use it for work all the time.

A bump map is just a black and white image (usually) used to create cheap detail. It already IS a \"normal map\". Its just used differently in the 3D application used to make the model in question. (like layers in your 2D app of choice)

Perhaps if you could describe exactly what you want?

ahh no.

a normal map has more information than a bump map.

I reinstalled photoshop and the nVidia plugin works perfectly now :D

A bump map is black and white, white symbolizing no change in z, while black making the lighting go to the back.

A normal map is mainly blue, with red and green representing z. It allows for the visual look as if stuff is popping out.
