So I have been once again exploring Sidefx Houdini over the last few weeks. Such an wicked 3D package. Going to try and post bit's and pieces I've been playing around with to keep it going :)
First Up - POP's (Particle Operators) driven by object based forces. Copied metaballs to the particle sim and added a customised SSS Shader to boot. The result is blob's transforming into a secret object!
