C4DtoA 3.3.6 uses Arnold 188.8.131.52 and is a minor feature release bringing improvements to the Density control in the Arnold Scatter object, exporting world space reference points and a bunch of bug fixes.
Cinema 4D S24 related issues:
- Textures stored in the new S24 Asset Browser are not supported yet, because of a limitation in the C4D SDK. Therefore porting material libraries from the Content Browser to the new Asset Browser is not recommended.
- Drag & drop nodes to the node editor does not work in S24, such as:
- Drag & drop an Arnold Material to create a reference.
- Drag & drop an object to create an object reference.
- Drag & drop a Vertex Map to create a Vertex Map shader.
- Ctrl + drag a shader in the node editor in S24 creates two copies instead of one. shift + drag and Shift + Alt + drag does not work.

- Progressive Render checkbox in the render settings: The Progressive Render setting is moved from the IPR Window to the Sampling section of the render settings. (c4dtoa#2378)
- Density scale in the Arnold Scatter object: A new option is added as the child of the Density parameter, which controls how many points are generated per surface area. For instance, the default 1 cm setting means 1 point on each square cm. (c4dtoa#2379).
Note, that Density now depends on the Project Scale. When you load an old scene where the Project Scale is not the default 1 cm, you have to set Points per square unit accordingly to match the look.
- World space reference points: Reference points can now be exported in world space in the Arnold Tag of a mesh. This can be useful for instance to stick texture when using a triplanar shader in world space. (c4dtoa#2420).
