some options are not saved between scenes

[smsaladi]

It looks like some option settings are not saved along with scenes, e.g. grid_mode, all_states, cartoon_cylindrical_helices. Is there a plan to include these along with scenes in the future? Is it something that I could help with a contribution?

Scenes do not store any settings. It's a reasonable feature request and we certainly accept contributions.

Things to consider:

• What's a user friendly API? Automatically storing all currently changed global settings might be too much. A separate command (like scene_set scenename, settingname, value) could work.
• float-type settings should probably support animation. In particular the transparency setting would be nice to interpolate.
• Do we need to support object-level or atom-level settings? E.g. to cross-fade two objects with transparency, we'd need at least object-level support.

Thanks -- there's more to this than I'd considered at first.

• I like a separate command for global settings that go along with a scene.

• Would you suggest going about this by making a modification to the MovieScene class to hold settings? Or is there a python (cython?) class that wraps the C class by chance? I'm still pretty unfamiliar with the codebase.

Supporting animation and object-level support sounds reasonable...

Yes correct, I would suggest to modify the MovieScene class, and maybe MovieSceneObject to support object-level settings. There are two ways to store settings, either with an instance of CSetting (used for global/object/object-state settings), or with a "unique setting" handle (used for atom settings). Using CSetting is probably easier. See layer1/Setting.h.

There is no python wrapper for the MovieScene class.
