How do you export a local normal map where z is up?
I think normally i would do r = X g = -Z b = Y
But there is no Switch GB button in the normal map panel in zbrush 3.5.
you’ll have to do it post.
simply copy G and B into layers and then paste them into the channel you’d like.
And what is a local normal map? you mean object spaced?
Yeah local = object space.
It’s unfortunate that there is nothing out of the box that will handle this issue.
agreed.
