Normal Maps - which dircection

(1/2) > >>


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?

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

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.

You can find some additional info here:

ok, thanks!
