dForce Tutorial Set : Fantastic Voyage!
dForce helps provides realism, primarily with cloth simulation but can be used for other creative and realism purposes. This new tutorial set reviews the fundamentals of the engine and then explores new applications for dForce demonstrated by Richard Schafermeyer (rgcincy).
This tutorial set is entitled Fantastic Voyage, invoking a sense of discovery. Richard re-creates a scene from the Fantastic Voyage movie by creating a dForce artery and blood cells. He explores the use of creating unique cave sets with dForce by using push modifiers. He'll even show you a new application for the physics engine by generating dForce terrains.
During 3 hours and 20 minutes we look at these projects:
Cave creation with stalactites
Recreation of a scene from the movie Fantastic Voyage: artery and blood cells
Terrain creation
Breast helpers
Realistic clothing: puffy sleeves and puffy trousers/pants
Skin indentation
Face deformation: fistfights for your characters!
Blindfold and wrist constraints.
These key principles will be taught when going through the projects above:
Using objects to help shape a target mesh
Changing an object(s) position during simulation to shape a mesh
Changing an object(s) scale during simulation to shape a mesh
Using an instance to see a hidden dForce simulation underway
Using a weight map in combination with moving objects to shape a mesh
Using a helper object to modify a mesh
Managing interfering body parts during a simulation
Using Contraction-Expansion Ratio to wrap a mesh during simulation
Using Contraction-Expansion Ratio to remove or add “cloth” during a simulation
About the presenter: Richard Schafermeyer (rgcincy)
Rich Schafermeyer is a long-time 3D artist and programmer. He got his start with the original Poser and Bryce 3D. In 2001, he wrote his first 3D modeler that evolved into the still available Shape Magic. He began to use Daz Studio in 2012. With a research and engineering background, the physics of dForce grabbed his attention! He decided it would be helpful to others if he shared his learnings and has frequently done so in the DAZ forums.
