Joseuz...

.. here's the project so you can see how it's done (the models are compiled in the project)

i downloaded your test 3dr...  how do i get the "compiled models" to show, seeing as the models don't exist on my machine...
all i see is the default yellow fish and boulder...

Cyper...
thanks... but my scenery lacked the "life" that yours had... lightmapping alone isn't enough... i found a lil success using Dave's (GeneTransfer) cubemap shader... but it requires that all scenery elements have the shader control their texture skins, which requires a different mesh for each different texture (a real pain when lightmapping stuff), or a single huge uvmapped texture for everything in the scene...

Georgio...
it is lightmapped... i used an old tool from called CShop from the old Blitz/Leadwerks community that lets me model and lightmap at the same time... point lights unnecessarily degrade performance and are limited to 4 (i think), though, through some creative logic, that should be enough... 

The textures could be a little more detailed

I agree, the textures could (and should) be a lil more detailed... i'm working on learning how to achieve this (suggestions and pointer to tuts appreciated)...

here are the models

cool thanks mike i'll check it out

The lighting is really very hard on large models if needed more from 4 point lights. But is it possible to make more point lights on the same skinmesh? Is there a shader or technique that allows more point lights than 4?

sorry i only just found the time to have a go at this. i hope you dont mind.
this was about 2 and a half hours for me and i know theres lots of improvements to made but i was rushing a bit.

i'm talking about RAD's poor lighting...
point lights don't cast shadows... scenes limited to 4 at a time... 

how do you circumvent these problems... or do you even see em as problems
when composing an interior scene...

examples below of 3DRAD point lights compared to Leadwerks point lights, and the
effects they have on almost identical scenery...

Whilst it is true that the pointlights are next to useless in Rad for actual scene lighting I don't think that poses a big problem in itself. Pointlights for lighting a scene are usually static so shadows/highlights can be built into the texture if you plan or lightmapped if you're clever. From my experience in Unity the dynamic lighting is far better but it really consumes resources and a couple of pointlights will cripple a game for an android system.
I think we've all proved in this thread that you can make a decent looking scene in Rad, maybe not the best, but good enough to generate some atmosphere, and after all good gameplay can take you to a place where your brain makes up the graphics anyway, I've used the example before but... Gran Turismo 1 came out and me and my friends loved the game and played it to death, we all thought the graphics were getting close to photorealistic, look at it now and the cars are boxes on wheels...
Today's AAA graphics are tomorrow's joke but yesterday's great gameplay is always great
