Explosion VFX
Unreal Engine 5 VFX Personal Work
Workflow Breakdown:
Create a sphere in Houdini, and use a mountain node to make it looks more interesting. Then create a burning source out of the shape.
Create a Dop network base on the source.
Cache the sim out to the local drive space so it could read faster in the following steps.
Get the cache to a time shift 100 frames back so it would not sim from the start then create a sphere like VDB volume and multiply to the smoke so it be came a smoke ball.
Create a camera and set it to film the smoke then use Mantra to render out 1-64 frames of the smoke sim, after that use mosaic to create a 8x8 flipbook texture
Create a grid and use turbulence noise to break the normal of the surface then render out a normal texture that I will use for distortion of the explosion.
Use a sphere to create debris by using the Voronoi fracture node. Then pack it into an HDA and render the FBX out so I can use it later in Niagara system.
Use Substance Designer to create a floor stain texture so I can use it for the explosion later in Niagara System.
