Maybe it's because Optifine isn't completely compatible with 1.5 if that's what you're using. I feel bad that I can't turn up any information on it. I'm 99.99% sure that it's not the textures because they're actually working in my install. (I installed Forge and for some reason that fixed it without anything else. But I don't recommend that as a fix because some people don't like Forge for whatever reason.)
Because I have to write up the text file that tells the game how to animate it now. They changed it up. I miss it, too. It really added a lot of depth to the world just because it would move. (Makes walking around not so boring.) Every so often college classes will rise up and make themselves a nuisance, too.
enjoy the pack and hope its on the customizer soon
but i have a question. i imported the origional Pack from the customizer ( was labled as Summerfields_29 and imported it into 1.5.1 format, but when i rezip and rename it will not load into Minecraft, the only way i can load it is through an unziped folder, i am using winRar.
basically i made the Wool the 4 block grids from the customizer as well as the Wooden and Iron door diffrent.
I noticed that the fire texture is different, and it seems a bit out of place looks wise. Maybe switch it back to Lithium's texture?
There wasn't actually a custom fire texture. Or at least none that I've ever found for SummerFields. I pulled the colors from the lava texture, but I think the issue is that it's too 'smooth' compared to everything else. It's been bugging me, too, but I can't figure out what to do to it to make it better.
