yes normally, there is. and you you don'T need multitexturing for that at
all.
i konw many engines (e.g. http://www.tashco.com/terraintexturing.html ,
http://baskuenen.cfxweb.net) which are bleneding the lightmap data on the
other texture...
further on if your map got a huge stride (distanstance between the next
vetex), shading won't be as nice as the lightmap way..
on the other hand with normal shading you can get great dynamic lighting
effects..
