Is your feature request related to a problem? Please describe.
Snowy grass, farmland and dirt path are not connected

Describe the solution you'd like
I suggest adding support for those blocks as well.

Describe alternatives you've considered
I tried adding them manually to advanced settings, farmland looked decent (for default resource pack), dirt path had a visible stripe and snowy grass is a form of grass block so I was unsure how to add that at all.

Additional context

• Dirt paths are not exactly a full-block, hence, the block behind can be seen.

• Normal farmland looks fine since they blend with the dirt block below, but hydrated farmland has the same problem as the dirt path.
  

• The way the mod works, connected snowy grass is not possible, as it is. (i will take a look at that later)

Dirt paths are not exactly a full-block, hence, the block behind can be seen.
Hydrated farmland has the same problem as the dirt path.

Is it possible to do something like connected textures where if the block above is a path /farmland block, a dirt block automatically makes its top pixels the same texture? I don't really know a lot about how mods work so please excuse me if this is stupid

I've added options for Farmlands and Dirt paths as booleans in 1.0.5, disabled by default, and a tooltip related to the 'visual bug' has been added.

I hope the dirt path and farmland issue can be addressed in the future. At some point I used a mod that did it perfectly, it might have been the original Better Foliage, or Optifine, not sure.

Fast and Fancy Snowy grass has been properly implemented in 1.0.10!

The full side of the block could be possible though, whether it is worth the effort is a different question.

No.
