thank's all
Bem, yes maybe i should vary the second wall, i think i will try it, but i'm a bit scary that it will mess out that wall.
Faraz, you're right for the chest, i have to breack the reflection a bit.
Sam, if you suggest that the glass blocks should be more refractive, maybe the suggestion from Bem is joining yours... you want to see less detail through the wall, well much more perturbated... i'll do some tests
thank's tom
