Houdini FX- Learn to emit dust from impact

Master emitting dust, debris, and sand from impact in Houdini FX, starting with dust creating points and crafting dynamic effects for any scale project.

Set up your houdini fx project by saving a project path, creating a ground plane with a grid, and building a points-based network for dust, sand, and debris effects.

Modify the crack and ground animations by scaling the crack, adding noise to the ground, and speeding the timeline to 100 frames with time shift and time warp.

Prepare geometry and transfer attributes in Houdini FX to drive dust and debris from impact by unpacking geometry, calculating velocities, and transferring color and velocity between body and ground.

Learn to emit dust from impact footsteps by adjusting geometry and normals with an attribute wrangle, and using vdb from polygons and volume sampling to create debris.

Create source points for particles to emit debris from impact, transfer velocity attributes, generate reflected velocities, and save the disk cache for consistent Houdini fx results.

Learn to convert transferred velocity from ground into reflected velocity that sprays debris in random directions when a crack hits the ground. Observe debris radiating in response to the reflection.

Emit dust from impact by building a pop network that computes reflected velocity, normalizes it, and scales by velocity magnitude for dust particles.

Learn to emit dust particles from hammer impact in Houdini by generating hammer hit points, trails, and velocities, then cache to disk and refine with attribute transfers and wrangles.

Generate dust trails from hammer swings by scattering points and applying randomized velocity with noise; keyframe emission and prepare for addressing stepping issues in the next videos.

Fix stepping by applying a time shift to backward frames and using linear interpolation. Add an attribute wrangle with randomization to compute particle positions for dust, sand, and debris.

Cast particle data to disk to enable fast playback, cache the sim points, and use a black null to drive dust and debris generation for subsequent sound work.

Learn to emit dust from impact by adjusting pscale in sand effects, applying ID-based randomness to scale between 0.2 and 1, and previewing in render view.

Fracture a sphere into pieces, scatter them onto points, and build debris in Houdini. Use Voronoi fracture, object merge, and match size with randomization to control scale and placement.

Create a dust source from a pyro solver to emit dust in the dust effects. Keep essential attributes (age, velocity, CD, p scale) and rasterize density, temperature, velocity, alpha.

Create dust with the pyro solver, boost density, tune velocity and turbulence, enable collisions with the robot, and prepare a render workflow with color, containers, and disk cache.

Adjust dust density in Houdini's pyro solver to achieve thicker dust, enable sand effects, and set up render pipelines from flipbooks to disk renders for dust, sand, and debris.

Compile and view dust, debris, sand image sequences in NUKE. Merge layers into a final composite and render to disk as a mov file.
