problem:
incomplete blocks such as grass, cherry petals, flowers, foliage and others. become too bright when the player flies away from them for a certain distance. on some blocks it is almost invisible. like cherry leaves. And for example, the vines, on the contrary, become very dark

expected:
incomplete blocks should not change their color depending on the distance.

I also noticed that a similar error is being tracked on this site. and my report is being linked to her as a duplicate, but it's not. they have a difference. please don't link my mistake to the one as a duplicate.

I was able to figure out what caused this error. Currently in the grass and fern tga file the background is made of white with minimal transparency. Because of this, as you move away, the texture of the grass begins to turn white in some places. This can be fixed by making the background of the grass texture in the tga file green with minimal transparency. With other incomplete blocks, things are a little different. They don't have a tga file in the game folder. That's why they darken with distance. This can again be corrected by adding to the background of the tga file the color that this block uses and making it zero transparency.

Thus, you need to make sure that the game, when moving away from an incomplete block, does not mix it with the background from the tga file.
