Hey guys,

I will explain about fixed reason because Half-Life SDK from Steam was miss understanding because bat file was written by Valve Software
Code:
makels BMP sampleswad samples.ls
qlumpy samples.ls
and BMP is not valid of directory and it just is "Samples"
That is a fault by Valve Software.

I explain clean and fix:
Code:
makels "source directory" "wadfile" "scriptfile"
It means this:
Code:
makels bitmaps owntextures myscript.ls
bitmaps is correct directory with custom textures
owntextures is generated wad filename as "owntextures.wad"
myscript.ls is batch for qlumpy and it generated to lines like this:
Code:
$DEST    "owntextures.wad"

$loadbmp    "C:\Users\JensPC\Documents\example\bitmaps\{CRATE.BMP"
{CRATE  miptex -1 -1 -1 -1
Than i go with qlumpy:
Code:
qlumpy myscript.ls
And qlumpy generated wad file. "owntextures.wad"

I hope my result helps you better if you do not need to use wally 1.5.5b if it doesn't exist internet like it is dead.
I am sure because makels and qlumpy make simple to us.

Enjoy your own wad file and publish to SC Database website if you want....
