I've thought over many ways to animate my viewport, but I can't think of any way to really animate it. What I have thought over: Lerping the arms to other part positions being complete copies of the arms. Rigging the darn thing and using regular animations (which limits things). Figuring out how I can animate easily with CFrames.
Anything else you want me to try?
P.S. If you said option 3, anything that could help me learn how to animate purely with CFrames?
P.S.S. Is there anyway to upload images here?
You could use RenderStepped to cframe parts in viewportframe. You could also replicate characters playing animations from the workspace to make them animated on the frame, but from my experiences it lags a lot if you overuse. You can also use tweens for moving =, resizing, changing transparency and other properties. Tweens are smooth and can have a lot of styles which might help you make good animations.
