[SOLVED][1.15.2] Fluid Viscosity & Fluid Overlay issue

[Slexom]

I have a custom fluid, it have to flow slower than water, like lava but not to that level. I've read the docs on FluidAttributes.java and it say:

 /**
     * Viscosity ("thickness") of the fluid - completely arbitrary; negative values are not
     * permissible.
     *
     * Default value is approximately the real-life density of water in m/s^2 (x10^-3).
     *
     * Higher viscosity means that a fluid flows more slowly, like molasses.
     * Lower viscosity means that a fluid flows more quickly, like helium.
     *
     */

I'm at 100000 now and still no difference with water. Here the initElements().

Also overlay not set correctly, maybe misplaced texture?

 

...
  
public void initElements() {
        fluidproperties = new ForgeFlowingFluid.Properties(
                () -> still,
                () -> flowing,
                FluidAttributes.builder(
                        new ResourceLocation("modid", "/fluids/still"),
                        new ResourceLocation("modid", "/fluids/flow")
                )
                        .luminosity(0)
                        .density(1800)
                        .viscosity(100000)
                        .overlay(new ResourceLocation("modid", "/fluids/overlay"))
                        //.overlay(new ResourceLocation("modid", "/fluids/overlay.png"))
        )
                .bucket(() -> bucket)
                .block(() -> block);
        still = (FlowingFluid) new FluidSource(fluidproperties).setRegistryName("my_fluid");
        flowing = (FlowingFluid) new ForgeFlowingFluid.Flowing(fluidproperties).setRegistryName("my_fluid_flowing");
        elements.blocks.add(() -> new FlowingFluidBlock(still, Block.Properties.create(Material.WATER)) {
        }.setRegistryName("my_fluid"));
        elements.items.add(() -> new BucketItem(still, new Item.Properties().containerItem(Items.BUCKET).maxStackSize(1).group(ItemGroup.MISC))
                .setRegistryName("my_fluid_bucket"));
    }
...

Try changing the ForgeFlowingFluid.Properties as well. In particular, the tickRate which affects how fast the fluid appears to flow. See how LavaFluid is setup to match.

I've put this as solved but I forgot that my problems are not 100% solved.
Still the overlay not apply. I've put the texture also in modid/textures/block/overlay.png because the vanilla water_overaly.png is in  assets\minecraft\textures\block . But not work that way. Do I have to generate the whole fluid in another way?

Look like there is so much confusion around the fluids, or maybe is just me... I was thinking the overlay props was related to the effect on top of everything you have when enter into a fluid, like the orange-red overlay(maybe called fog?? but the sense is that) you have in lava. But, instead, is the texture that apply on the side of the fluid. 

So now I've a light blue fog but I want to have it of another color. Setting the props color  do nothing but glitching the side of the fluid with a full black texture(?). I've looked in LavaFluid.java for some reference but nothing found.
Here a screenshot.

How did you solve the fog color isue? I've been looking at this but got nothing.
