[Closed] bi normals and tangents
Hi guys, i’m progressing slightly further on my maxscript exporter, and i’m now onto tangents and binormals. I’m aware that they are used for normal mapping, but to be honest, thats all i really know about them.
If someone has the time, can someone give me a quick explanation of how these work, and maybe a quick guide how to derive them through maxscript?
Thank you for your time.
p.s. if they are in the helpfile and i’m missing it, bobo i apologize
You may try the Tech Artist Wiki for some information on it. You could also try a google search for “binormal shading”. It will return a lot of game dev information, but you may be able to extract what you need from there.
