Creating new MatLibs.

In truth, neither my way works now... :tsktsk:

I think I have some weird stuff inside my editor... I will check it out later... :eww:

After having a lot of trouble today, I deicded to post here:

My textures for the argilla bricks, with the consistent weight of 1,33 MB per one, doesn't work, when I try to import the matlib... :( After an entire day of attempts to create T3_FAC matlibs in any way, I gived up. At this point I tried a simple experiment: I copied, obviously with another name, a couple of dds (_D and _N) from the originals, and I tried to create T3_FAC with those textures, and thas is the result:

Well, this seems to work.

So, I think that the trouble could be some kind of difference between mine and the two official textures, since the different weight (just 129 KB for the official _D and 512 for its _N)

Someone can give me an hint on how creating DDS of the same weight (and of the same kind)?

I can speak for photoshop settings. I just leave everything by default, dtx1, no alpha. No mipmaps and 2d texture are selected. Then, all come in same file size, 512x512 ones become 128k, 1024x1024 ones are 512k, and 256x256 ones are 33k.

The only problems I had was the usual unreal engine calamity, naming conventions. I make sure there are no spaces in texture names, and double check that the file name I'm trying to import has totally unique name. You know, after a while, everything can be wall1, wall2, wall3...which will confuse the editor and they won't show up. Because there might other textures with the same name in the original textures. Even two different matlibs shouldn't have the same named textures, even they're in different folders. I spent a whole night trying to figure out what was wrong, renaming the file solved the problem. (You have to re-create the whole matlib though.)

Other than these, I can import everything fine. I have a cheap method for importing transparent textures, but I'm sure Judith can step in to tell you how to do that exactly, if not more properly.

Nice! :D I though that other than 8 . 8 . 8 . 8 ARGB 32 bpp | unsigned doesn't worked...

Instead the currect image setting is DXT1 RGB 4 bpp | no alpha!

Well, now I will create quickly a trial matlib, let's see..

Huh, funny thing!

The CrazyBump gives me a normal map 1,33 MB weight, and if I reconvert it with Photoshop with your settings, it give me this:

It's important or is just a nonsense? And if I click OK, nothing relevant happens?

Flux on 27/7/2008 at 23:25

I think it's ok, settings with no alpha, hence "alpha information will be lost". I never saw that in ps. Unless, Judith corrects me, that would be ok to proceed.

Judith on 28/7/2008 at 00:03

DXT1 is the biggest compression and no alpha channel. Good for typical textures. If you need transparency and/or plan to simulate specularity, use DXT3.

Normalmaps are a problem though, no matter which compression method you use, their quality suffers greatly and they become pixelated. It would be great not to use compression at all, but uncompressed 1024x1024 dds file weighs 3 mb :eww:

My textures for the argilla (clay) bricks,

Let me help you with that translation.

You were right :D. I was confused with "terracotta" that is another italian word relating that material, used also in english. But I don't have time nor energies to stand correcting any tosh I write - of course not in the writing for the wiki, which before I pass it to some persons more "englished" than me. Please excuse me, I just studied nine years french at the school :tsktsk: (and I never wanted to study it :( my wish were english). But I was forced to study it, due to the school norms. And my english is all self-taught (more translators :p ).

It's funny looking how you germans (are you german? :weird: )are fussy in language :joke: Before also Beleg noticed me of some my error

I'm not German, but since my region was for claimed by either Austrians or Italians for centuries, I have some Austrian blood and some Italian blood.
You might consider me more of an alpine Italian.
