I try to paint landscape without smooth texture blending. Using simple material and blend textures via Alpha channel. But have some issue with Ring like corners in the segments where one texture is contacted with another - grass (green color) with ice (blue).
How i can make all square corners for the blending?
After some time there is some solution. Not so good, but may be helpful for someone who need create landscape with shapr edges (eg. for low poly or Voxel style games):
Paint final landscape version
Save mask textures for ecah layer (Right mouse button on a texture layer -> Export to file)
Import these textures again in to the project. Set NoMipMaps and Texture Group: 2D Pixels
Modify Landscape material and do blending for each layer via new textures
