constrain layer to camera

[mattmos]

Hey mohos,

is there a way to constrain a layer to the camera? I have an animated image seq which was rendered out from blender, and want to pin that layer to the camera so that i can animate the camera and match the movement (roughly) of the 3d camera.

Or would it be possible to import animation from a 3d camera into moho?

Cheers,
Matt

In the layer settings there is a checkbox to set a layer “immune to camera movements”. It has to be in the root of the document. So not in a group.

Ah brilliant, thank you so much!

One last question, is it possible to copy keyframes from a layer to a camera? I'm tryin in the motion graph but don't seem to be able to paste frames onto the camera channels, even after seperating into each axis.

You can only copy camera keys to the camera channels. If you want to do it any other way you need to use custom scripts.

If you get to the point of wanting to script a solution, this (nearly 10 years old and untouched since) might at least steer. https://www.mediafire.com/file/upewb49h ... 0.zip/file

It was originally designed to unload camera keys from one moho doc and load them into another; but native moho functionality took over (copy / paste between docs). However, it could form the basis of unloading from one group of channels to create a data file that could be loaded into the camera channels.

e,g. Export takes a "source" layer and creates its output file in which

translation becomes camera position
x/y rotation become tilt / pan
z rotation becomes roll
z scale becomes zoom

Then import works as before.

All, ofc, with updates to support whatever has changed in AS/Moho since then...

cool, thank you for the quick help.

And thanks for the script idea, I'll take a look but right now its probably just one shot that i need to replicate the movement so it might be overkill. Will save it for later though
