Also dig in data/config/r3dopengl.cfg you can find many kewl options there.

And what .html page do you recommend me to read?

Blender creates normal maps in camera space, while I need tangetial space. These normal maps from blender are useless for CS.

Thats correct. I know that work is in progress and I hope we can expect something useful soon. But atm you need Melody, ORB, etc.

For example "Bumpmap with specular" download that file, open in blender and see how things are set insde.
Examples are best way to learn.

Nothing special in settings. Check b2cs examples at b2cs.delcorp.org

Here is tool for this and good explanation
http://developer.nvidia.com/object/melody_home.html

- it's not proper color for flat normal map, find and read on CS site "Artist's best practices"
- with flat normalmap shading will be flat, nothing wrong here, to see smooth result you need "real" normalmap baked from hi-poly model
- also don't forget to enable 'diffuse' renderloop

if you use CEL then try quest sytem with trigger 'entersector'

probably entities are invalid hen. check why.
and always valid your pointers using if, don't let it crash e.g.:

mypointer->GetIt ()
if (mypointer)
  SomethingElseUsing (mypointer);
else
  printf ("your pointer is ivalid");

you need to choose your way - c++ or scripting, pure CS or CS+CEL, low level/high level coding, or just click and play in b2cs.
you can find many tutorials in docs/html/manual, at www.crystalspace3d.org and b2cs.delcorp.org

oh come on, it was little sarcasm about artist's copyrights worries

But no offence BOU, we just like humour here
Here is valid url http://b2cs.delcorp.org/index.php/ArtistInstall
Also today I'm working on big package contains CS, CEL, blender, python and b2cs. I'll give url soon.
Greetings

Here is link to premade CS artist distribution:

Imagine it without the words "DAREK Preview"

In theory - yes. But in very manual way, nothing automated.

what kind of blender animation did you use ? it should be sequence of the object, maybe you just animating mesh ?

You need to paste here blender console output, without this it's impossible to recognize what is wrong.

Sounds cool.
For your environment you can you hundrets of free models laying in the internet thrash I think this is not a problem. Try 'blender model repository' or 'gamasutra exchange'.
