Week 06: Dust and Helicopter Destruction Test
Creating dust with Pyro in Houdini has always been a challenge for me. Surprisingly, with the experience gained from past projects, I was able to achieve about 80% of my desired look within just a few tries. In addition, I will be showcasing a test of the Helicopter Destruction, featuring the constraint network I set up last week.
I. Dust sourcing
Sourcing emitter for dust is similar to sourcing Debris and Particle, I will link the process of setting up the sourcing here if you are interested: Ground Destruction - Debris and Particles
Shaping constitutes the primary focus of this phase. After visualizing the dust cloud's direction by tracing lines from these particles, I generated the dust's age, causing it to fade out from its active frame to a certain distance traveled. Leveraging the 'curveu' attribute, I allocated more points to the tip of each emitter, resulting in fewer emitting points the further they travel along the trail. Additionally, I linked the dust's density to its age, causing it to decrease as the dust ages.
