Custom Tile sets Problem.

[chopinski]

I'm converting some tile sets from variuos games to use in a project but im having an annoying problem, there's no smooth edges when i use the new tile sets, they are always sharp at the edges when crossing 2 custom ones. See the picture->

As you can see, when the snow goes through both custom tiles it has smooth edges, but when one custom goes through another custom its a square, ugly and sharp. Any way to correct it?

Btw, im using blp lap to convert the images.

There might be a way, but it could be a cheap workaround which is setting the tile to be below the others.
Modify Tileset > Shift Left

Didnt work

It just dicides which one is on top.

Hmmm I don't know , hopefully someone can help

Looks like it is lacking alpha? Alpha blending is used for the smooth edges. If the BLP file has no alpha, or the terrain texture was not painted with alpha then you will get sharp edges.

Hmm, I'm beginning to understand, so, that's what im doing ->

Looks like the original image has no alpha (right?) "Alpha channel: 0 bits", and when i'm going to convert it to BLP i got these options on the left windows. So there's anyway to add alpha to images? Which option should i select in the "alpha channel options" to make it work?

Thx!

The source image has no alpha. It will not blend. That is not a tile texture...

Tile textures are divided into 4*4 or 8*4 different tile components. Each has a specific use case and meaning. This is not SC2.

4*4 is basic tile type with 2 core variations and all blend boarders. 8*4 is extended tile type with 18 core variations and all blend boarders. 8*4 extended is used when texture dimensions are wider than tall, for example 512*512 is basic where as 512*511 is extended. I would recommend 512*508 as each tile part is then a round number of texels (64*127). Currently that is the closest you can get to HD terrain due to hard coded limits on maximum usable mipmap size (512*512).

Attached is the summer grass extended texture to give you an idea of the layout. Notice the alpha on the blend tiles.
