Untextured Blocks are EPIC!!!

this work for mods too? i have a problem with a mod, and item is glitched and is with a purple and black texture

I'm not sure if anyone even answers here anymore, but all I did was change the dirt texture to a 32x32 png file, and it broke. I followed the guide, and the texture followed everything on it. I have no idea what is wrong.

Hello! I have what I feel may be a fairly simple issue, but for the life of me I cannot seem to fix it. Allow me first to explain, upon installing minecraft for the first time, I already knew what to expect from the game as I had seen my yopunger siblings playing it before. Knowing then that the graphics were going to be fairly basic, I looked into downloading/purchasing a couple of different Resource Packs. To my dismay, attempting to run them simultaneoulsy side by side made for some funky mismatched textures between the two, as i assumed they were competing for domain over each other. So, I quickly dropped both texture packs, and began to conglomerate my own franken-pack so to speak through mixing and matching what I both liked and did not like between the two packs to create my ideal Minecraft experience. This had been going close to seamlessly, until I encountered a problem at the very end which has had me stuck at a roadblock for several hours. The problem I am having is that certain dirt blocks with grass on them will not display some of the sides, instead displaying the texture described above. The funny thing is it seems to only be affecting certain blocks and not others, or perhaps one face of the blocks? thinking this was the problem, I went into the block textures folder in my Resource pack and tried duplicating the grass_side texture and grass_side_n texture hoping that it would solve the problem as it seemed to when I was having a similar problem with plain dirt blocks, but it has not worked and I am at my wits end. Perhaps somebody here will be able to offer some useful advice, or perhaps I can even send the pack through email or some other way so that it can be looked at by someone more experienced? Any advice or help would be much appreciated, because I paid for one of the resource packs I would very very much like to get this problem solved!
Cheers!
