Fourth and fifth week
Run and jump Animation.
2D animation
The 2D jump animation turned out well for me. However, Aidan advised me to focus on 3D animation and complete 2D animation only as a lecture assignment. Nevertheless, I see progress—this time the animation was easier to understand in terms of both movement and form, but I know I still have a long way to go before I can animate in 2D. I also used Toon Boom Harmony this time.

3D animation
During the lecture, we had to watch and animate the main jump poses using constant interpolation to understand the most important poses. I used several examples and found one where the jump is quite powerful. I placed the main details, but I didn’t really enjoy animating in constant mode—maybe because you have to manually add more movement, which can create overly choppy animation. However, the main point was the experience, even though I prefer animating with curve interpolation. I hadn’t used the graph editor that much before, so this was a new experience in how to change curves. After adding both the main movements and details, I switched to the curve editor. I had to fix the arm rotation, but the main details looked good. However, after Alec’s notes, I had to add more movement and more details when converting the animation from constant interpolation to curves, so that Blender’s software would calculate it more correctly. For the jump, I used a good example I found on YouTube where the jump has larger movement. I used it more to add small details and include greater rotational motion in the arms, and to understand how to transition from a standing pose to the jump’s starting pose.

Running and jumping over the fence took the most time, considering that I had to combine two separate animations. Using Rachel’s attached tutorial as well as various samples taken from the internet, I realized that the given sports equipment wouldn’t work for me, so I made a simple metal fence and added a metal texture. Using compositing, I also added a camera with a rig system and added light objects, as well as inserted a standard PBR material for the asphalt ground, which gives texture to the ground. I animated the camera slightly so it moves along with the Rain character. I positioned the light objects so it would look like it’s happening at night. However, to better read the movement, I also made a render without the moving camera.
My idea was that my character would be running away from something, for example an angry dog or something else, so I chose an unusual object for Rain to jump over. Therefore, I chose warm lighting and a slightly bluish tone for the atmosphere, and created a metal chain-link fence.
Animation before the change
In the last lecture, Rachel advised me to change the shape and angle so that when jumping, Rain creates the correct geometry and so her body moves with the jump, leaning over slightly. After that, the animation became much more readable and natural.

I rendered the finished animation in EEVEE, and it turned out surprisingly well.
Reference research
For the actual jump movement, I used an example of how to jump from a video I found online. I thought this video was a perfect example of how the arms and legs move, so I used it, although I changed the arm direction slightly, taking into account that Rain has a lig
hter form and the angle when Rain’s body bends. In my opinion, I managed to create the movement quite well, although combining the two animations together wasn’t simple. Perhaps next time I’ll try using the NLA track editor to combine two animations together.

Problem using action editor.
A problem I couldn’t really solve was that sometimes movements were copied over to another action, which was quite annoying, and in the end I partially solved it by pushing down to the NLA tracks editor, although there’s probably another solution to this problem. Therefore, all animations in the final files are located in NLA tracks.
I finally found a solution: in the other animations, I need to insert keyframes for FK in the transition movement when the arm changes from IK to FK.
Conclusions
The main conclusion for animations is that for each animation I used a different frame count: 20 for running to make it easier to calculate; 32 frames for the first walk, which was a bit inconvenient to animate; and about 40 frames for the walk with personality because it has a larger step and slower speed of movement. I concluded that with each 2D animation attempt, I got better at shape consistency and I could draw one frame faster. I understood how to better place timing and learned a bit about the graph editor, but I’m still not that familiar with animation with curves, though the animation turned out better. I’ll probably need to practice more with the graph editor. I had worked with animation mixing before but not on such a large scale, so this was a good attempt. Overall, I believe I started to better understand timing and rotation during animation, as well as body movement, especially arm movement. I think my animations turned out reasonably okay, but I definitely need to learn more about studying references.
