I have not experimented with floors ...I will soon but for walls or other horizontal things it works. You don't even need Thea but you do need sketchup.
With thea you can burn in the details in a rock or wood grain and shadow as in my "Tudor to Contemporary" post.
You can adjust the amount of bump or grain in Thea with displacement or by placing a normal (made from the texture with nvidia's normal tools) in the bump panel.
You just need to put the sun in the position that is most neutral so the shadow is cast downward..this way it works in a movie. You can bake in shadows in any direction if it is to match the sun in a still shot....but baked shadows do not move
go here for an example of this texture (and stone texture) in use.. http://ibuildmodels.com/ROD2.html
.....as in example
1. Make a profile of overlapping sideing board in sketchup. set your camera straight on and fill the screen, shadows off. You need to build a whole wall.
2. Ad your flat, grained texture
3. Export to Thea...it will come in at the same view and perspective.
4. Adjust your sun position in thea....ad bump or depth and bake for a bit, I usually get enough with a regular nonbiased setting in 30 minutes. Map your new texture in Sketchup
. Import your model into Lumion.
5. Open your new baked texture in PS and make a normal with nvidia tools
6. Go to Lumion with the resulting textures and normals and adjust bump...etc.
