Hello. I'm a programmer looking to add some 3D assets to my game. I have played around with both Blender and Sketchup, and for my limited 3D modelling experience I'm finding I can make far more interesting models/scenes in Sketchup than blender, but I couldn't find any free lightmap baking tools for sketchup, whereas my understanding is that this is available in blender for free.
So, my question is, how can I setup a workflow whereby I can do most if not all of my work in Sketchup, and only use Blender to create the lightmaps? Is there any way to define light information in Sketchup, but have blender render the light-maps? Otherwise I'm going to have to do all the modeling in sketchup and then add the lights manually in blender every time I make a change to the scene.
Also, I couldn't find information specifically about blender and the dual texture effect in Xna Reach. Does anyone have information/tutorial/etc.. for getting lightmaps calculated with blender into Xna and rendered using the dual texture effect in xna reach (i.e. on windows phone 7).
