Sorry if this is a Noob question - but is there a simple way to translate a height map into a normal map?
thanks
Dave
"Crazybump" will artificially create one. Normal Maps are typically created from an subdivided highres model from it's original source.
There are tools for this:

Thanks but I need to create one in JS/ dynamically.
