Normal Maps - which dircection

(1/2) > >>

Hi!

There are two ways to interpret normal maps (Y up or Y down) and it is very hard to identify what kind of normal map ons has. You guys always say "flip Y", but this seems not always right.

I there a way to implement something in corona helping finding out what normal map is used?

Beanzvision:
Knowing what to flip will come down to your eye and personal taste on how the normal map should look.

TomG:
Yep, unfortunately normal maps don't contain any information about how they were generated or what was chosen for the up/down directions or which axis is which color. This means there's no way for software to even make a 'guess' at what is correct, leaving it to the viewer to make sure that things expected to be indented or popping out are correctly looking indented or popping out.
