Shading and Shader Building (Kai Stavginski)
This masterclass provides an overview of new and existing shading features in Houdini 15. This includes an introduction to the new SHOP shaders as well as shading and layering in VOPs. We also take a deeper look at working with BSDFs to build custom shaders.
Loops in Sops and Vops (Jeff Lait)
Houdini 15 has introduced a new way to do loops in VOPs and SOPs. This masterclass provides an overview of the new looping constructs. With the new constructs; effects that used to require significant technical knowledge to achieve with Foreach SOPs can now be readily built.
Grain Solver (Jeff Lait)
Houdini's grain solver uses Position Based Dynamics to simulate sand. This masterclass describes what that means and re-builds the sand solver from microsolvers. It also provides some insight and advice in how to tweak the grain solver's parameters to get the effects you desire.
