Filters are a great way to make high quality animations for your texture packs. They can provide a wide variety of effects, and can make your textures look truly amazing. They have one downside, however: the output of all animation filters is a layered image, with each frame in its own layer. All the frames must be copied over into another image before they can be used in Minecraft. This process can become extremely time-consuming, especially when you have twenty animations to do, with over three dozen frames each.
