Reflection or refraction problem

The facade of building I am rendering is made of many horizontal glass cilinder diameter 10cm.
When I get close to building I have strange reflection or maybe refraction problem.
It seams that I lose reflection at the distance.
Any sugestions.


What is the material on the walls?

best regards,

At a guess…what is your max refraction depth on the material???

If it is set to default of 5 then it probably isn’t enough…try raising it [sometimes I go as high as 20 if there are many overlapping glass objects.

Hope it helps

material…

It seams the problem was in geometry because my cilinders have 6 sides and now I corected that to 18 and it looks ok.
