Blender 2.82a Mantaflow Flip Fluids Water Simulation in Cycles - Glass Mario Pipe Loop-De-Loop HD

No tutorial followed. My goal for this project was to clean up the fluid object boundary (make it smooth), however i did not seem to be able to achieve this. Primarily because of all the other issues i faced (i am a beginner after all.) But hopefully the week long practice has taught me something. Some issues included: Making the pipe mesh to start with. (joining objects seamlessly) Leaking fluid obstacle. Normals not being.... normal. & not being able to get that smooth finish. Background HDR sourced from: http://www.hdrlabs.com/sibl/archive.html
