Modelhead, Can you take the time for make a tutorial of that, or maybe upload a resoult of reflection in Lumion floor with the use of that baked textures??

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.

Questions?

Modelhead, You were not talking about reflections?
Forgive me for asking you to prepare it a tutorial, but for me were talking about the poor reflection of Lumion and comparing with the various software and reflection techniques.
When you've said that with baked textures in horizontal surfaces the result was pretty good and did not require many minutes ... Take away some reputation points if it makes you feel better.  :D Sorry man. ???

We opted for reflection maps because it's really the only technique which works on all objects. What you see here is achieved by mirroring the scene in the reflection plane and rendering everything again. To prevent objects from sticking out a clip plane is used. The reflected scene is rendered to a texture and used on the ground surface for example to create the final image. The problem with this method is that it halves performance but some times it's worth it and you just have to make sure you don't have too many reflecting planes.

Thinking out loud: if the reflected mirror map had a transform applied, which squeezes it by 1/2, then presumably would one not end up with a very good faked Raytraced reflections/refraction effect?

p.s. hard to stay on the subject too many great points are being raised under this thread.
