Basic texture editing

[Sathe]

So basically, I took a texture made by someone else, scaled it up to 2048x2048, added a few things and then plopped it back in the game. The problem however, is now the texture seems to have some lighting issues that are rather hard to describe(making them hard to google). How can I fix this? I realize not much texture modding goes on here so if this is the wrong section feel free to point me in the right direction please.

A few screenshots of the lighting issue...

Also, there is an annoying neck seam, but as I understand that is not possible to fix.

Again, if there's a better place to ask this question please point me to it.

Oh, what settings you used to save as dds format?

Do they 'glow' ? (yea hard to describe)

appearently this looks like because of the black rgb in the normal map.

*Generally* for the skin texture, you can use dxt 1 no alpha np with it

But you must use dxt 5 interpolated alpha for the normal map as the alpha channel in it has various gray area between black and white.

If you save it as dxt1 1bit alpha format with black alpha channel then rgb information may be lost. Only white area will remain

Additionally just scaling them up has not much good effect. No effect on visible resolution change, 2^ times of memory use, if you want 2048 texture then use 2048 from the beginning. or use 4096 to edit and downsize it.

I scaled it up to add bits (pink bits ) to the texture that didn't look very good at the old resolution, I used gimp with the normal mapping and dds plugin, for the DDS I saved as dxt1 with generate mipmap and for the normalmap I used dxt5 with mipmaps.

I wouldn't say they glow, it more looks like its amplifying the light, the sides that are directly exposed to it are very bright while the sides hidden from the light are extra dark.

In photo 1 you can seen the darkness and in photo 2 the bright (compared to the tail)

EDIT: the exact format I used in gimp was BC1/DTX1 for DDS and BC3/DTX5 for the normal map.

[movomo]

Yes you're right amplifying seems to be fit rather than glowing

Would you post the textures? I'm curious

I think this pic is the same prblem as yours. IIRC I accidentally saved it as dxt1 1bit alpha.

[Sathe]

I suppose so, I'm rather embarrassed by my artistic skills (cut, paste, eraser) but take a look if you want.

Did you want the DDS's or the PSD.... I'l post both...

Forum doesn't like those file types.... to Media Fire!

You have the nvidia dds plugin then you should be able to apply the normal map filter.

Ever opened up any normal map file? They are full of strange blue or rainbow colors with bumps. You cannot do it yourself, allow nvidia plugin to do its job.

Or just leave the origianl normal map alone. The size of the color map and the normal map don't need to be identical, you can use it without any edit

edit: wait a sec don't ninja me

edit2:

here's the quick edit.

open your psd, you need 'genitial' layer

apply the filter to that layer and copy it to the original normal map.

I was just following the F-INevOblivion skinset guide

EDIT: except for using that skin instead of the base ones in the F-INevOblivion pack

[movomo]

I don't know much about gimp as I use photoshop myself. But it should be simple to use the filter. This seems to be helpful.

Oh well anyway thanks for the good file. On reflection I've always needed the hi rez textures for khajiits. Probably I'll use your texture. If you end up with creating a normal map yourself post it too please

[Sathe]

trying to learn the normalmap, whenever I open a normalmap all I see is this:

but when I make them I get something similar to this:

at first I thought all the normalmaps were blank but they have a very subtle amount of blue..

why do existing ones look like an empty document?

[movomo]

The second one is right.

But no idea what's going on in GIMP. I've never tried it. Every normal map in Oblivion looks like the second one, I mean as far as I can tell.

Save that one and try if it solves the problem.

[Sathe]

well it works as a texture, a very very bad one made of rough glass... I'm going to see about photoshop then

[movomo]

If you have phothoshop or photoshop element or whatever download this and install it

[Sathe]

Well, time to download photoshop I guess.

EDIT: Oops, didn't think the first message went through >.<

[Sathe]

Here's the normal map. Please don't credit me with anything, this is MissAniThropes Kawa-Khajiits with changed resolutions and very slight changes.

Whatever. Thanks for the khajiit texture with clitoris anyway. good work.
