Challenges & Obstacles

There were several challenges and obstacles throughout the realisation of this project. Perhaps the largest was to find a suitable fluid library and getting it working sufficiently well for the immersion that we aimed for. The library needed to support either Unity HDRP or Unity URP since we wanted to work with Unity Graph for the flames effect.We found our best option to be Obi Physics fluid library.  The next problems were to learn and tweak the functionalities of the library to interact not only with the scene correctly, but the flames, to create the chemical reactions. Throughout this project, wenever really knew if it was gonna succeed. We were also constantly against the wall of GPU limitations since fluid simulations are very costly.
Balancing learning with immersion was a notable design challenge, since immersive learning can require further functionality that requires significant time efforts. Perhaps the biggest obstacle of all was that the fluid collision with the bottles which never got completely fixed - the fluids can still escape straight to the bottle through quick movements. Any attempt at increasing bottle collision density to prevent this caused a severe spike in lag due to GPU limits.
