Download & Documentation:








Check out the README.md. In general you can just load up the asset and it should work. If you want to permanently Install it edit your houdini.env. Refer to the Houdini Help. For a quick permanent Installation with the Shelf and Icon you can copy the content into your houdini home directory. it will need the content of /toolbar , /otls, and /icons. On the next start of Houdini you should be able to add a new Shelf called VDB Painter that includes the mbPainter tool with 2 Scripted Shelf Tools from the qLib that allow to turn off Guides and switch the Houdini Background.

A lot of thought and work went into the Paramter Window. It is simplified and allows quick access to all needed Parameters. Switching between the 3 Modes works with Buttons therefor only Active Parameters will be Shown.
