cheat reflection angle

[muoto]

Hello,

to simulate small variations in a big glass facade, i would like to "cheat" a little the reflection of the glass in each glass panel, so that the reflection is slightly different.

How would i do that ?

Thanks !

Bump map per panel in reflections map?

[muoto]

yeah, i am trying that at the moment, small basic gradiant ramp with "planar from xyz", and than 3-4 small value differences in the bump amount.
It seems doing the trick
