+===== Adding custom textures to your fluid =====
+To create a fluid with custom textures, you will need at least 2 new textures, with an optional 3rd, overlay texture that is shown when you look at the fluid behind glass or leaves. All textures go in the block textures folder.
-If you want to use your own fluid textures, you can refer to vanilla's assets ((''assets/minecraft/blockstates/water.json''\\ ''assets/minecraft/models/block/water.json''\\ ''assets/minecraft/textures/block/water_still.png''\\ ''assets/minecraft/textures/block/water_still.png.mcmeta''\\ ''assets/minecraft/textures/block/water_flow.png''\\ ''assets/minecraft/textures/block/water_flow.png.mcmeta'')) as a template.
+The first texture should be named YOUR_FLUID_NAME_still.png, and can optionally be animated.
+The second texture should be named YOUR_FLUID_NAME_flowing.png, and should have double the size in the dimensions. For example, if your still texture has frames of 16x16, the flowing should have frames of 32x32. It can also be animated.
+The third will be named YOUR_FLUID_NAME_overlay.png, and should not be animated.
+Using our acid example, the client initializer will look like this:
+<code java [enable_line_numbers="true"]>
+@Environment(EnvType.CLIENT)
+public class TutorialModClient implements ClientModInitializer {
+	@Override
+	public void onInitializeClient() {
+		FluidRenderHandlerRegistry.INSTANCE.register(TutorialMod.ACID_SOURCE, TutorialMod.FLOWING_ACID, new SimpleFluidRenderHandler(
+			Identifier.fromNamespaceAndPath("tutorial", "block/acid_still"),
+			Identifier.fromNamespaceAndPath("tutorial", "block/acid_flowing"),
+			Identifier.fromNamespaceAndPath("tutorial", "block/acid_overlay") /*optional tint can go after the overlay*/);
+		BlockRenderLayerMap.putFluids(ChunkSectionLayer.TRANSLUCENT, TutorialMod.ACID_SOURCE, TutorialMod.FLOWING_ACID);
+	}
+}
+</code>
+You can refer to vanilla's assets ((''assets/minecraft/textures/block/water_still.png''\\ ''assets/minecraft/textures/block/water_still.png.mcmeta''\\ ''assets/minecraft/textures/block/water_flow.png''\\ ''assets/minecraft/textures/block/water_flow.png.mcmeta'' \\ ''assets/minecraft/textures/block/water_overlay.png'')) as a template for your own textures.
