The mesh has gaps when the adjacent two grids have different materials.

Question

Look like this: alt text If I move the camera,some gaps will disappear and others will appear.
I'm trying to generate a random map, the random mechanism:
1, a random two-dimensional map data
2, according to the map data to judge different states and number them,
Just like : 3, record different number of triangles
4, depending on the number of triangular grid filled with different material Here is the tutorial site. [link text][3] And then the gaps appear when the adjacent two grids have different materials. How can i fix the bug?

Well your UV coordinates are clearly off by one pixel. This happens when you don't target the pixel center but the pixel border. Also if you don't use point filtering for your images you should always add some padding pixels around the image rect, otherwise the neighbor pixel colors will bleed into your image.

See this answer for reference.

Thanks for your answer.
the way doesn't work,but i have found another way to solve it.(it takes a lot of time.)
1,turn off the Anti Aliasing.(Edit -> Project Settings -> Quality -> Anti Aliasing -> Disabled)
2,change the materials's shader.
Add image by using shader(Unlit/Transparent),and change the material shader to (Sprites/Default),and tick the Pixel Snap.

Thank you ! Your solution solved my issue with that type of shader
