Thanks, I am planning to learn lite-c immediately after my demo project grin I know I should be updated grin

This is the normal map shader I want to use:

I don't know what is wrong but the model I assigned this effect turns dark. why?

skin 1 is color map and skin 2 is a 24 bit bmp for normal map. What is wrong?

Should I save my normal map in a special way? any configs in photoshop? or maybe wed?

I don't care!
