Older version called renderEngine had been move to versions folder, if you still interested.
Wrapper class for the maxon and c4d API of popular render engine for Cinema 4D.
Intended for more user-friendly manipulation of node materials with the new maxon.GraphNode model.And also with Octane Node Material model.
Provide helper class for convenient access AOV , Material , Scene Object(Object/Tag/Light/...) in Cinema 4D popular renderer.
Happy Rendering and Scpriting!
- Octane
- Node Materials with the new GraphNode model
- Redshift ( Only Node Material for Material Helper)
- Arnold ( Only Node Material for Material Helper)
- Waiting for more...
Boghma is a open community for c4d developers, we are trying to make it easier for everyone to create plugins and share them.
This library is also included in Boghma python library.
You can install our free plugin Boghma Plugin Manager and install any plugin you want, this library will be automatically installed or updated.
If you want to share your free plugins or libaray, please join us in Join Us.
All the boghma plugins and boghma library are personal FREE.
- (Recommend) Download Boghma Plugin Manager and install any plugin, the boghma lib will auto installed or updated.
- Download the source code and import it to your Cinema 4D.
- For some reasons, AddShader-like methods(maxon.GraphModelInterface.AddChild) will add the node in the center of the graph, if we call those methods on exsited material, it will return a mess graph, you can call Renderer.ArrangeAll() after.
- Material(except Octane) helper only support material with the new GraphNode model(Node Material after R26)
- Due to Octane use his Custom UserArea UI base on old layer system, and didn't support python, we can only modify Octane materials in material level, but can not interactive with selections in octane node editor.
- Also Octane materials didn't have a "port" or "wire" context, we can not use all those methods as same as NodeGraghHelper.
- Arnold mask tag SetPrameter has a refresh bug.
