Hey is not big deal !
problem was how achieve effect of floor lamp. Because use lumi ball and transparency with blur refraction on the lamp shader is the best idea...I did that. But this basic idea is the first step to suicide I had to avoid problem.
Transparency+blur is the best solution but because we do not have Surface Shaders in Kray we must suffer

But it is one solution:
1. We must use lumi ball
2. we must use transparency
3. We must use blur rerfaction
In point 3, then bigger parameter of refraction blur then better effect ...and the best way to kill cpu.
So I used lumi ball with gradient (pic above) + small effect (10%, which still is slow but not that to make time render "infinite") I wanted also make visible metal strings from inside. Actually this freaking lamp took ~30% of time render next ~20% was curtains....so you see how necessary KraySurfacesShader as additional is....
Btw English imho is only one language to share information , this language are international and will be more in future. Civilization goes to dual language (mother tongue and English) In next generations will be normal (and required!) dual language everywhere....and this will be normal.
