Sprite Format (727)

I am absolutely baffled by some issue regarding sprites. I am trying to add this sprite to my 727 cache:

but when I pack it and then load it up ingame or even look at it in Steve's sprite editor again, it has this cancer blue background thing that I have no idea how it is even getting that data and adding it to the background?

What could cause it to be going from transparent, to that auto added background. When I decode the sprite and write it to a file, it looks correct. When I encode it and then decode that encoded data, it looks correct, but when I load it up ingame or with steve's sprite editor, it has that blue background circle.

Very helpful. Thank you.

Sorry. What happens if you pack other sprites? Do you get a blue background too?

I don't perfectly know the cache's sprite format, but isn't there an option to have multiple images in the same file? Are you sure you're repacking the sprite file to only have this image, instead of the blue background + this new image? Also, I'm assuming you're rewriting your ref. table and that this blue background image isn't an old image you forgot to update, right?

No, I just figured it out. I had to quantize the image because of the palette being too large (turns out RS3 has higher color count availability than 727), so the textures rendering on models has the transparent value just fine now.

However, I am not sure if the textures that particles use render transparency differently or something, because any particle textures that I encode end up having a similar lack of transparency issue after quantizing the image or not.

The sprite that is being attached to the texture is just this one:

Nevermind, I fixed the particle issue as well. I was running a few too many extra texture parameters. Packing the texture with only the sprite operation is the way to achieve particle transparency.
