How do I edit/make _n maps?


Recommended Posts

I've been making a retex of Vampire's Edge, mostly as practice. Since I haven't gotten around to learning how to make retex mods propper in GECK, I'm editing Zenith92's retex instead.

 

It was kind of a trial and error thing but I'm very pleased with the results. However, I kinda ran into trouble with the normal maps. I'd like the hilt of the sword to have that slightly corroded look of the original texture, but Zenith's retex uses a kinda different-looking blade which makes the light reflect wrong on the texture I've made.

 

I tried editing the _n files to correct this but doing so seems to make them stop working or something; the sword ends up looking all glossy.

 

I tried getting around this by simply extracting the vanilla Chinese Officer's sword textures and using those maps instead. But I was surprised to find that this gives my texture a very shiny, brand-new kinda look; pretty much the same as Jingwei's Shocksword, actually. While this isn't a bad look in itself, it's not what I originally had in mind and more to the point, I have no idea why this happens.

 

So, what am I missing here?

Aha! Saving as DXT5 helped. Thanks. :smile:

 

I still can't figure out how to lower or raise the alpha, though. >>

there are several ways, one easy one is to grab an eraser tool, make it huge and set its opacity to something like 80% then erase the entire layer.. the leftovers will be at 20% opacity.

alternately you can open the normal map, duplicate the layer, delete the background layer so that its transparent, then lower the opacity to whatever you want on the duplicate layer and press ctrl+shift+e (in photoshop) to merge down to 1 layer again.

Okay then, I'll keep experimenting and see what I get. Thanks for the help, it's appriciated.
