Rice- MK64 Texture Issue

[Weatherton]

I'm sorry for making an entire topic about this, but I'm not sure if you've seen the problems I'm having or not... please go to The MK64 texture topic and see if you can help fix the problems I'm having with replacing character textures... I'd really appreciate it.

Here's an example picture:

so far that's the best my texture has looked

perhaps posting the texture and its alpha would also help.

First of all, it's not your texture.
Second, I took that screenshot.
Third, a new topic was not necessary.

Although a new topic may not have been necessary, he made the 3d model and created the texture from it. He also didn't claim that he took the screenshot.

[Dejital]

Oh, my mistake, I thought somebody else made the texture. >_<
I need to go stick something up my butt.

I'm trying to replace the attached Yoshi image with the attached MagiKoopa image (I change the name of the MagiKoopa image to taht of the Yoshi image and place it in my hi res folder). As far as I can tell there aren't any alphas for these textures... if I'm not posting the things you were asking for please let me know

I think the whole problem is that it's color indexed.
I don't think we'll be able to improve any of the karts.

I find it hard to believe that there are no alphas, or else we'd be playing black squares on the tracks with buggies in them.

EDIT: ...unless the alpha is actually a specific color in the palette. It's a good way to save memory. In that case you would have apply the original's palette on the upgraded version. Diffuse gradiants help here.

I suggest trying one step at a time to isolate the problem. I would take the original texture, scale it x4 (nearest neighbor) and save it immidiatelly. If *that* doesn't work, then it's highly unlikely that it's a palette problem, unless your image software changes data that it shouldn't when resaving the image.

EDIT2: Attached is a quick example I did with the palettes. This uses exactly the same colors (no more no less) of the original.

The problem is the alpha channel. Alpha is not a specific color in the palette, it is within the palette. Each palette entry is a 32-bit word, has RGBA values, not just RGB. When you see the palette panel in your image editing software, it has 256 colors, and each of the 256 color has its alpha value.

I think Weatherton's problem is the alpha values of the generate texture. If you can make the palette complete right, not only the color values, but also the alpha, your texture should work just the one below. I added a red X onto the kart texture, and it works.

I have to agree that it is very tricky to work on such CI textures.

Ok, I don't want to sound like an idiot but I didn't quite understand what you were saying I need to do. I have adobe photoshop and that's what I've been using... is there anyway you could explain a more step-wise method for ensuring proper alpha usage? Again, I'm sorry that I didn't understand; it sounds very well described.
