My plot was breaking the glasses with Pdi, then add fluids in a second step, however I was worried about whether the weight of liquids would affect the way the glasses breaks or not, so I decided to test it by filling the objects with Maya nParticles, and setting the fragments as Maya nBodies and Pdi Fracture Bodies at the same time, it was perfectly possible and I baked a couple of scenes with different Pdi Fracture settings in this way. However I needed the neck of the glasses to remain as one single piece so finally I splitted the glass in 2 parts using “Uniform” style before applying radial shattering. PDi counts with several patterns to shatter the models, fist I did was testing them, I started using “local” shatter style, because of the easy of setting the exact impact point, however I discarded it later because the fragments generated looked more like egg-shell than broken glass, using “radial” style in around 200 fragments each glass and I got a high realistic look, I found out that I had only to adjust the pivot of the model to make cracks matching the impact point with the ball so it was perfect. Besides looking at the web I hardly found any good test of Pulldownit and fluids, so I was a little scary about doing it, but I have to say it was much easier than expected. I decided to make a 3 glasses shot for being more genuine than the usual “wineglass breaking”. I started this project with the aim of testing how Pulldownit behaves along with Cg fluids, and also as a practice in the use of Pulldownit plugin which was pretty new to me.
