I alsow played with pure-ambient lights, but there are terribly slow to 
render.

In my case the solution was - to use assumed_gamma 1.0 (or even 0.7)
Other thing - swith for a test all textures to pigment rgb .9 and difffuse 
.8 or .9

#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
