Houdini RBD: Glass Fracture

📖Hi! Here I'm showing how you can do a simple RBD bullet solver simulation of a window broken by a projectile. I will also show you how you can fix jitter in your simulation pieces, fix velocities and angular velocities, and preparing your geometry to be rendereable (removing internal faces that are connected). 💻This is the expression used in the attribute wrangle: float start_frame = chf("start_frame"); float multiplier = chf("multiplier"); float time = max(0, @Frame - start_frame); float factor = max(0,1-time*multiplier); v@v *= factor; v@w *= factor; ▶️Chapters: 0:00 Introduction 0:33 Glass, window frame, and projectile model. 3:13 Fracturing the glass geometry using points. 7:30 Glue constrain 10:10 RBD bullet solver 12:50 Fix velocities and angular velocities 21:10 Fix jittering pieces 29:00 Connected pieces inner faces. 📱 Socials Website: www.jerostique.com IG: jerostique
