I tend to do my animation on a plain blank unmorphed figure, as it’s easier and smoother to animate. Then I save out the aniBlock. Then I load my saved scene with the fully clothed morphed figure and load the aniBlock and tweak if necessary.
To save out a custom Aiko, just save the scene - File Menu > Save As > Scene.
To load the custom figure into an existing scene, do File Menu > Merge. Or if you have saved the scene into a Content folder, then you should just be able to find the folder on the Content menu and double click the icon instead of merging.
To save out and restore an aniBlock:
My content folder for DS4 is Documents\DAZ 3D\Studio\My Library. If you have that folder, or one like it, then you should have a subfolder called aniBlocks. Create a subfolder in there for your name, or project name, eg MyAnimals. Then when you save out your aniBlock, save to that folder.
Down at the bottom left of the aniMate2 tab, you should see “aniBlocks” with a little arrow. Click that arrow, and it will show you a little window with your aniBlocks folder, and your folder MyAnimals will appear under one of the plus signs, probably.
You can then click your folder, and your aniBlocks saved in that folder will be arrayed along the bottom of the aniMate2 tab, so you can load them into the scene.
First picture shows my custom folder Caroline with subfolders. Second picture is after I have clicked on the Birds folder.
If you don’t like the window going away all the time, you can right click “aniBlocks” and choose Preferences and untick Auto hide folder picker.
