Colobot: Gold Edition Logo 3rd Revision

[DavivaD]

So how I'm supposed to make it looking evenly? Shape of this logo is so hard for lightning that I can add here even 50 light sources ant there will be always some flaws. I checked if environment lightning would help a bit, but the effect was just disgusting. I guess now I could try lower a bit the brightness of some source lights and that would be possibly all I can do for this logo. Or maybe someone have any other idea?
