These shots have been done for the Sinopec TVC back in 2017. These are some early test renders and simulations that were done by Thinking Particles and rendered in V-Ray 3ds Max. unfortunately, these shots drastically changed due to the client's requests and modifications and ended up very different in the final product. anyway, I thought it might be worthy to share.
