@SPARKY1922 Lol, well now you'll find it easier going backwards. :)
So here's an example of 'green screen' that I'm working on right now. I used blue instead of green because of the eyeglass reflection. You can use any color as long as the color is not in something that you wouldn't want to disappear like eyes or clothes.

This is a playlist someone made of Sims 3 animations:

This is an AMAZING resource for animations. There are so many it's hard to get straight and this girl created a picture book of some of the best animators creations to remind you of what the animation looks like. The link to the document is in the description of the video.

Here are my two favorite pose sites, again these are still poses, no movement. I don't use them much anymore since learning to use animation for videos. You do need the pose mod to use these.
