I didn't think about using the moho-helper-object! Nice. I did try to fix it that way for a bit, but didn't get far. Might not work in this case? I do feel you should be able to update moho.document after creating new files... I hope we can get some API updates, generating moho files is kind of an ...

It looks like this may be a somewhat similar case as modeless dialogs before the helper object, where the initial document state persists throughout the entirety of the function run. In this case, the moho object passed to the run function cannot be changed until the function is initiated/run again....

Since there's no API for copying layers across documents, I *think* you'd need to do this: 1. create your new document and save it, like you're doing (there's no need to open this file, as it should already be the current document) 2. use something like loadDoc = moho:LoadDocument(path) to load the ...

If you can pare the file down to the minimum that still makes it crash using layer selector, you could post it here for others to investigate.

Otherwise, it's just shots in the dark at this point.

Curvers are basically just warp meshes, but with tons of small slices. So having curvers manipulate other curvers could be multiplying the performance hit. I'd suggest using regular bone chains and curvers, rather than stacking curvers. Like Daxel said, try removing things from a copy of the file, t...

There should be a content warning on this. Language, violence, and gore.

Without seeing the image, my first guess would be colorize layer in the layer settings.

Using "Expand mask by one pixel" helps a lot, but if that's not good enough, you can always move a reference of the bottom layer to the top and remove its fill, instead of using exclude strokes.

564KB for a complex file is deceptive, as the file format is actually a zip archive with a much larger file compressed inside. My next guess would be using layer references. Sometime these have been known to get "corrupted." Deleting them and remaking them seems to help in this case. You m...

I'd start by checking if there are keyframes in the negative timeline: viewtopic.php?t=32714

Glad to help. Welcome to Moho scripting.

Here's a thread with a similar sounding problem: viewtopic.php?t=36327

Layerscripts (embedded) allow a script to make changes without adding keyframes. They are evaluated on every frame, and can do a lot. They can change values of things on the fly and effect the render, but for more complex things, like utilizing actions, it's just much simpler to add the keyframes to...

You might try setting Edit>Preferrences>Timeline>Frame interval display to zero, to help reduce clutter.

Those Lua errors are due to a script function only available in v14. There are no readily available alternates for earlier versions of Moho.
