How do you alter the textures of lava and water, but still keep the animation?
You need to use Xaus HD texture fix, you can find it here: Xaus HD texture fix
Edit: I am thinking the HD texture fix is not what you were wanting. I have seen players use a separate .png file for custom water and lava animations. They name them like this: custom_water_flowing and custom_water_still. Here is a couple of the .pngs for examples: custom_water_flowing] custom_water_still

Hope this helps.
