help getting variation in glass facade

[gfriedman]

i would like my silicon-butt-joined glass facade to have the slight variations in reflections that a real facade would have - glass is never perfectly flat and reflections 'break' from one panel to the next. What's the best way to do this? Noise modifier? something in the texture itself? Anyone know of any good tut's for this???

 

thanks

Have you tried using a large noise modifier very gently in the bump slot, and then uvw map per face?

[gfriedman]

no I have not. this I will try.

 

I did not know you could use noise mod in the bump slot. I was applying it to the gemoetry itself, but I found I could not a get a good handle on its behaviour.

 

and the uvw map per face - should I use a script for this? am I just setting them to different channels of a muti id material?

- create your geometry

 

- create your glass material

 

- put a noise modifier in the bump slot with very low values

 

- apply the material to your geometry

 

- select your geometry -> apply uvw modifier -> select "face"

 

should make a difference... I'm sure you could take it further. If you search the forums for "glass material" you should find lots of discussions on the topic.
