Hi @louvfx
Generally speaking with a few exceptions, only a single subtool can ever be active at any given time and Layer information is stored on a per subtool basis. If your eyes are on one subtool and the body on another, both of those subtools would need an active Layer in recording mode to record the changes. A Layer does not store information for any other subtool other than the one it was created for.
So you could create a Layer for the eye subtool and create a Layer for the body subtool. Leave both the Layers in recording mode. Both subtools could be moved at the same time using Transpose Multi-select mode, but supported transformations in that mode are limited. If you then click through each subtool and exit recording mode, you can toggle off the the updated position for each subtool individually.
If you want to just try out some poses, a simpler solution would be to simply merge the eyes into the body subtool. If you have good polygrouping, you can simply use the Polygrouping selection shortcuts to hide or mask them if you don’t want to affect them with an operation.
You can then create poses for the entire body as a whole at the same time, then split the eyes afterward back into a separate subtool. If both subtools have the same number of subdivision levels and are merged at the highest level, they should form a new subtool with the same number of subdivision levels. They can then be split with one of the Split functions in the subtool palette, and retain those subdivision levels.
