Dynamite is a Python script for Houdini that fits perfectly for the iterative 3D asset development environment, where changes to low and high poly geometry are introduced on a frequent basis.
The script streamlines the process of creating cages and reduces tediousness of recreating them whenever the model is replaced by a newer version. With Dynamite you won't need to redo cages of objects which weren't modified in the last iteration, and only those that were altered will require your attention. This reduces the time that would otherwise be spent on redoing all cages from scratch on each consecutive asset iteration.

The initial commit is a beta version (0.9.0) and might still have some bugs that I wasn't able to spot after some major refactoring, even though I did my best to find them before releasing the tool. Please report any of them here or on project's GitHub page.
