Removing alpha channel from normal maps

[My-Key]

Many people keep asking about removing alpha channel from normal maps, so I've made this small tutorial This is the cheapest way

1. Download software which can open tga files (for example InfranView)
2. Open normal map with that soft and save it as a BMP
3. Open new bmp file and save it as tga
4. Be happy

Hello My-Key,

thanks for posting this, i am one of the ones who don�t know to handle that..

Please let me ask me a question: Can i use your normal maps from the QRP pack, overwriting the ones from Rygel? What do i do with the included gloss-files? Overwriting them too or not copying them?

[My-Key]

As far as I remember Rygel's pack contains quite old version of modified QRP textures, so probably they won't fit. I suggest to use official textures, but if you want to use Rygel's I don't forbid You only have to test if they work together properly or not.

Thank you My-Key.

May I add your words here regarding the _bump textures as well:

"Bumps are automaticly used as a map for parallaxmapping if there isn't any normal for that texture. So you must convert bump to normal and everything should be ok"

This will of course help fighting this issue as well.


@ TR2N
I spent many many weeks comparing Rygels normals with My-Key�s one by one half a year ago. So I can tell you for sure, that My-Key�s normal will NOT fit 100% to all diffuse maps in Rygel�s pack.
Reason:
Rygel used some different diffuse textures.
But around 90% will fit.

Regarding _gloss textures:
My-Key uses very few _gloss files (compared to Rygel. He used _gloss for everything)
So this question can be answered by yourself.

Kind Regards,
Seven
