Hi, i'm making a custom map for GTA 2 and whenever i import a tile, these black dots appear. Does anyone know why that happens and how do i get rid of them?

My guess would be that you saved this yellow tile as a PNG or a GIF with transparent color enabled, resulting in the dots of that color displaying like this. Does this sound like something that could have happened?

Nah, i converted them to 8 bit bmp before importing, and the original tile didn't have any black dots on it.

My guess is that when you imported the tile, you probably changed the palette which supports the image. The problem is that the game always uses the first color of the palette as the transparent one. Therefore the original devs always reserved the first color of each palette as black, as you can see for the original palettes.

To check if these black dots are the transparent colour, turn on "flat" on the block with the tiles and see if these black dots become transparent. Or alternatively, check if the first color of the palette you used for this tile is the one missing in the tile (which I presume to be some yellow color)

So, i did that, and it turns out that these black dots became transparent.

pallete index 0 will be black & transparent. you need to be careful on how you convert / export to bmp and how palette is applied.
