    Hello, I'm using a 24bit png 2048x2048 pixels as normal map, but I get a very jagged and awful result...

    I'm not using compression for the bitmap, so I really can't understand why it's so bad...
    Any help would be much appreciated!
    Many thanks

    Did you set the texture type and filter mode correctly?

    Do you use Compression?

    If your PNG is 24bit, then I think you're getting one 8bit channel converted to an 8bit heightmap. Save your image as a 16bit grayscale image.
