Keyframed animation of multiple sketches?

[kmatzen]

Hi everyone, I need some help understanding how hard it might be to extend Open Brush to incorporate multiple canvases into one scene with each canvas' pose being keyframed to form an animation.

I do see the existing animation timeline experimental feature, but I'm not really looking for flipbook style animation. I'd like to craft several 3D sketches that can be rotated and translated over time.

Ideally, I'd like to be able to combine this with other assets such as point clouds and meshes that could similarly be keyframed by pose or by visibility.

One feature that would also be useful here is to be able to import a keyframed camera path. I see you can create a camera path, but once I combine the sketches with external point clouds and meshes, I'd like to make sure I can import related camera paths for a final render.

I skimmed some of the code and the layer feature looks relevant. Do you think there's a way that I could hijack that and assign it a keyframed transform?

I'm looking for hacky solutions for now. If you have some idea that you think could help hack together a prototype app, but aren't necessarily the correct way to do it long term, let me know anyway. Thanks!

You should take a closer look at the animation timeline branch as it already does some of this.

There's two modes - flipbook (each frame has different content i.e. it's a different canvas) and transform-based (currently reusing the camera path splines but there's no reason the transforms couldn't be defined any way you choose)

Additionally take a look at the plugin scripting branch - this allows layers (canvases) to be transformed via runtime lua scripts. This feature hasn't had a huge amount of testing but it works in principle.
