Oh sorry, thank you. I totally missed that.

@ferdinand Yes. it's solved. Thank you.

Hi @Yakuza just in case you do have space in your Cinema 4D space, so the projectool don't understand clearly your input so you need to escape it by adding "" so something like: kernel_app_64bit.exe g_updateproject="D:\MAXON_CODE\Maxon Cinema 4D 2023_CODE\sdk" Cheers, Maxime.

hello, We need to ask if you are compiling the SDK, your own project, etc. Different question, you should open a different thread It will help other people to find the thread. Cheers, Manuel

In your specific example, it could look like this: static maxon::Result<NodeData*> Alloc() { iferr_scope; return NewObj(SoloPrefs) iferr_return; } And when you construct your NodeDataclass, you have to access the actual value of maxon::Result: SoloPrefs::Alloc().GetValue(); Note, if that allocation fails that you can access the error with GetError(). There have changed lots of things, Sebastian already posted the links to the relevant documentation.
