irradiance maps

about files for irradiance / light cache maps

Hello, i try to make what show in tutorial for fast render using save maps (...), yes it`s more faster, not 500% or nearest of that, but yes more faster.
I have something wrong, i think, the result is more dark than the original, and the faster is not significant ( 50%).
maybe i use thing wrong ? light...parameters...?

I hope some one can help me,

Thanks

i see that

Not sure i understand you correctly, but if you save your maps you should decrease the rendering time equal to what it takes to calculate them.

And about the render getting darker, i have no clue.
