Weirdness in hi-res texture loading

[Lord A.]

I started redoing Duke Nukem 64 [U]'s textures a few days ago, and a few hours ago I remade a "world texture".. It loaded fine the first time, but I wasn't happy with it, so I altered it a bit.. Then it wouldn't load the texture anymore.. After a few hours of frustration, I simply selected the whole image and pressed delete, so the layer went blank, thus the image was just a transparent layer.. I saved it like that, and went into the game, and wtf ... the texture was loaded, just the way it was before I deleted the layer's contents.. Then I decided to try another similar texture, first stage's road texture.. And the same thing, after making the image, I had to empty the layer with del, or the original texture appeared in-game....

I was wondering has anyone else encountered anything like this, and perhaps know a solution to this.? It's a real pain in the ass if you want to alter the texture again later, since you'll have to do it all over instead of just modifying it....

You have to make sure, that the texture has a color depth of 32-Bit.
Means: 24-Bit for colors and 8-Bit for transparency.
If you filled out the complete texture, Photoshop and Paint Shop Pro most likely converts the texture automatically into a 24-Bit texture when saved although it was 32-Bit before you saved. Just make sure one single pixel has a transparency of 1% or so then it will be a 32-Bit texture when saved

Also make sure you're editting the PNG files

And of course: The new textures need to be 1, 2, 3 or 4 times the size of the original texture.

Thanks, V-King, they needed the transparent pixel, problem solved....
