I have a tile based map which I generate using interpolation of pixels on a reference bitmap into appropriate tiles depending on the color of the pixel.
I'm trying to make the output look natural in which blocks of similar tiles look like they are forming a single entity as in the following image:
While my version only puts static sprites onto aligned cells, the second image takes forest tiles and smashes them together like a whole single forest. The same is done for the water area.
Could someone explain or point me somewhere where I can learn how to make the result of the first image look like the second? Thank you
Also, how are the seamless road connections done in the above image?
