Re: normal and bump maps together

Thanks Alan! :-) Didn't find any input on the normal map node to connect two of them though, but combining with a single normal map and multiple bump maps works.

Hi Arvid,

Use the output of one as the input of the other ( i.e. base normal).

As far as boosting a normal map you can't push it beyond 1 (the fading
is just faked anyway) though you may be able to
cheat the effect by using the same normal map twice - one as the base

for the other.

Cheers,

Alan.
