I'v been trying to make a stone block with grass on top but I'm having hard time getting the side colors correct; I got the top part to work but not the sides. Note that I DO have the texture names and files in the right places, I am experienced with mods already (though I have never been able to fully publish it but plan to).
Here is the picture of the two blocks next to each other, the side colors don't match.
And here is the code.
