That kinda works but I don't
think it's quite what wr3yth is asking for. With Immune To Camera, you're basically 'pinning' the layer to the camera and it's the camera that's doing all the moving, not the layer. Depending on the animation you need, that can work for many situations but this isn't really the camera following a moving item.
Being able to constrain the camera to other items would be useful but, unfortunately, I don't think this is currently possible in Moho. (At least, not that I'm aware of.)
I've run into situations a few times where I needed the camera to follow an item, and I wound up exporting the Moho output to a 3D program instead. I wish we had more options for the camera to interact with bones, layers, etc. For that matter, I'd like to see Moho get a upgrade for camera/render output options common to other 2D and 3D programs. (i.e, deep color support for PNG and EXR, special channel buffers like motion vectors, depth, shape/style IDs, etc., etc.) Getting actual 3D lights in the environment would be useful too...not just for realistic lighting fx (like in After Effects and other compositing/3D/2D animation programs,) but as a controller for Moho's 2D shading fx. (You can probably
kinda do that now but to be really practical, this needs to be a lot easier setup and edit.)
Sorry, for going off on a tangent there. It's all kinda related...to me anyway.
