Thank you for showing the interest to lend a hand. I assure you that if I didn't feel this urge to know what I have in my hands, I wouldn't insist. I know I could make a fool out of myself but I don't care.
I'll probably never need more than what this shader demonstrates in the example but it's just I'd like to fully understand it's possibilities, that's why I'm asking things
. So,
[...] This means, assuming you use it on terrains and / or entities, you can have a multitexture normalmapping shader with 5 texture + normalmaps max!
And you said something about a total of 28 monochrome channels, if alpha channels are considered.
The example and what you just said implies 3 textures with 3 normal maps.
I'm surely missing something here
