The grass in the distance is brighter than that near

Reproduction: Fly a little higher, then look at the grass in the distance and the tall grass. The grass in the distance and the tall grass map have a higher brightness

The reason is that some plants use tga textures because the blurred distant view will mix the colors of the transparent parts together. Therefore, tga is used to make the colors of the transparent parts similar to those of the opaque parts so that the blurred distant view looks more normal. However, after the texture update, for the tga textures of grass and tall grass, the transparent parts are all white, which means that the official has not processed it at all Therefore, the grass and the tall grass in the distance appear to brighten up directly, very jarring

Solution: Handle grass.tga and tall_grass.tga
