Lightening, perhaps you are sure ,
but Ogre3D already has light management with shaders , so it won't be difficult for them to add it.

Shaders of the demo are pixel shaders , well for the rest , perhaps ,don't forget they are programmers not 3D artists

And it's the beginning , just wait 6 months to see if the engine will continue ot exist , improve on lot of things.

ok the engine can be flammed in it's actual state and it's really oubvious price indeed
i think we would flame it less if the price was 100 $ instead of 4000 to 10000$

Indeed the authors are crazy about pricing
