Hell I want to draw in my gui fluid texture e.g water, lava but Im having troubles of getting ResourceLocation of teqture from FluidStack

 

 

I understand your point, but is it possible to get default blockstate and get a texture out of that ?

You can use Fluid#getBlockState to get the corresponding block state for a fluid. Then you can render that block state.

Or render the fluid state you already have with BlockRendererDispatcher#renderFluid (func_228794_a_)

Something like this?

private static TextureAtlasSprite getStillFluidSprite(FluidStack fluidStack) {
        Fluid fluid = fluidStack.getFluid();
        FluidAttributes attributes = fluid.getAttributes();
        ResourceLocation fluidStill = attributes.getStillTexture(fluidStack);
        return Minecraft.getInstance().getTextureGetter(PlayerContainer.LOCATION_BLOCKS_TEXTURE).apply(fluidStill);
}
