Alright since there is interest in animating with a monthly focus here it goes.
This month I decided on a basic key element of weight, we can easily have characters or objects of completely identical size and shape that convey different weights. This is done by how long it takes them to move, poses suggesting struggle, how much anticipation there is in interaction and other various techniques. So the goal for this month is to come out of it more confident in properly expressing weight along with more creative ways to showcase it in your personal reels. Because everyone has different levels of experience and varying amounts of free time to commit to side tasks like this challenge I broke it into 3 tiers, someone might want to do a tier a week, others might want to just commit to one for the whole month.
Here are the tiers:
Tier 1 :):
Concept: Animate a character staying in place picking up an object (around 10 seconds long)
Focus: Conveying the weight of the object being acted upon, try to do this with creativity instead of the redundant character picking up heavy box/barrel/ball/etc maybe something as subtle as a hand picking up a can on a shelf.
Tier 2 :D:
Concept: Animate a moving character (walking up to an object, pushing object, etc) interacting with the object.
Focus: Now you are conveying the weight of the object and the character fully, you might have a massive character pick up something like a small pebble, keep in mind lots of animation is subtle so it’s easy to do an extreme like a massive rock being lifted. Think about things like when you lift a pencil how do you visually know it is light? maybe because you can balance it on a pinkie?

[b]Tier 3 
:
[/b]Concept: Animate 2 characters interacting physically to convey both of their weights in an interesting way.
Focus: The key here is interacting physically maybe a mother picking up a child to see out a window, or two characters wrestling and tossing each other around. This will really work on the use of constraints as well to properly convey interaction. This is for those who want a completed sequence of quality animation conveying weight, creativity, and interest between characters. The fact that the object (box,ball,prisim,etc.) is now animated and living too creates new issues and challenges for animation.
Please share posts related to this month in this thread, and for suggestions on improving the challenge in the future, thoughts on it like if you think the tier idea is good or bad post those in the general thread here: http://forums.cgsociety.org/showthread.php?p=7227540
Lastly try to use your creativity to the fullest, if you are thinking of doing an animation/scene that you have scene in 125091238 demo reels think of something new. This is to improve your creativity and give you a unique clip to expand on or keep as is for your reel if you want. Everyone has seen the typical character try to lift heavy brick/rock/ball/cube/your object here. What about a hand twirling a pencil around the fingers? A guy lifting a vertical sliding door to a garage? think outside the norm. Weight is in every aspect of our life, take a day to watch people and contemplate what they do and how it visually conveys how much something weighs.
Good luck, have fun, and learn a thing or two!
