This week we developed our Rube Goldberg machines. I started to continue on from last week and create more elements to my machine.
I decided I wanted to make a ball that went down an obstacle course and then through a ‘bubble machine’ and floated up as a bubble, and make it a satisfying loop.
Firstly I started on the physics design. I wanted to create something simple, but satisfying, that would also work well with my bubble machine design. I kept the original animation made with bullet from last week as the starting point, and added two passive rigid body slides the bubble would fall into. I then made a twist slide the bubble would go through and made it a hollow passive rigid body to make this possible.
I then did the same thing to two more slides that the bubble would pass through, and started making the design for the main element of the bubble machine.
Here I baked my animation so no aprt of the design process would mess the animation up. I then started focusing more on what my design would look like, I decided a pastel pallete, and a cute aesthetic would fit this machine. I added a bubble background image for the machine and added coloured surfaces to each part of my model. These included chrime, plastic and frosted glass. I also added a bubble texture to the ball itself.
I then added a ‘clear water’ texture to the window of my bubble machine so it would create the illusion of a bubble being made.
I also added details like the metal pipe the bubble would come out of.
Work from home
My task for myself this week was to complete the machine ready for the camera rendering next week. I felt I needed to add more detail to this machine as the actual physics were quite simplistic.
I found the perfect hdri background and lighting source on Poly Haven. It is a pastel power plant, which was exactly the aesthetic I wanted.
I wanted to add a sign for the machine and the little bubble machine. I found a bubble font I liked and then made 3D text to input on top of my model and on top of my bubble machine.
I then added a foam border to my machine, making it look neater more complete. I also rounded off the dominoes at the start, and also did this to the slides, making a more bubbly look for all of the machine components. I played around with texturing also, and finalised any errors on my geometry.
I then added an animation of bubbles coming out of a pipe at the top of the whole machine for the whole animation, just for an added effect.
