Did you know that in Blender you can easily animate oscillating objects with a single driver expression? ✨ 1. Select your object 2. In its rotation write: "# sin(frame / 300 * pi * 2 * 3) * 0.5" where 3 is the number of swings it does, and... 0.5 is the amplitude multiplier (use a bigger number for bigger swings), and 300 is your end frame 3. Enjoy the perfect loop! #b3dshow more

wait I can repost old stuff and still get likes? 😳

Great tip! Another thing you might want to know is that "2 * pi" is a value that pops up quite often in formulas that there's a name for it. It's called "tau", and Blender actually recognizes it as a constant, which is pretty sweet as it makes a lot of expressions simpler.

yeah I checked and tau actually works, good catch! 👍

I'm relatively new to drivers... Sin(frame/15.9)*0.5 gives the exact same result. Are the extra variables just for human readability and control?

yes, exactly! those kind of micro-optimizations aren't relevant even in realtime code anymore (like gamedev), let alone blender driver expressions that only run once per frame. compilers are smart enough to do those optimizations for you in most cases anyways

Oi! Blender is hard enough already! No need to throw math in there as well.

😅

Great tip. You are not passive star, you are active for sure, so many tips 😍

Thanks 😅

For optimization, you should simplify your formula: frame /300 * pi *3 * 2 can be simplified to frame/50 * pi. This will remove 2 multiplications from what the CPU has to do per frame.

No need to, python precalculates those for you
