Shadow-baking will be done in Lightwave. That is no problem. The problem is:
Blending 2 uv-sets over each other. The first one contains normal-mapping or parallax shader (with tileable textues) and the second one contains a lightmap (non-tileable). The lightmap can even contain colors to simulate static lights.
A simple multiplication of the lightmap should do the job. But it must take a different uv-map into consideration.
