Week 1

For this unit, I was in Group 8 with Marina, Franciska, Jing Jin, and Daisy. Before the start of this unit, we were given time to create a logline and synopsis to plan for the story of the animation project. I tried to make a story about a food critic and a waiter.

During the first group discussion, we quickly decided on a story to use for the animation, to which Daisy’s story was chosen. The main idea of the logline was about a baby bird flying out of its nest. Afterwards, we moved on to brainstorming ideas and details for the script.

The script was later finalised by Marina, in which the story was about the bird learning how to hunt for worms. After getting a better idea of the storyline, we began to research the art direction we will be following for the project. In the shared Pinterest board, we all had the same general agreement that the story would take place in a lush garden with cartoonish style characters. In the end, we narrowed it down to a Disney and Ghibli inspired style and decided to look for environments with open skies and warm colours that are suitable for the mood of the animation. We intended to create an animation that appeals to young audiences, and a flat illustrative style appears to appeal to this demographic based on our research.

Week 2

After finding ample references, we started producing sketches for character designs based on the art styles of the images we found on Pinterest.

We decided to follow the design made by Jin as it was simple yet effective, and she also made the turnaround sheet which will later be used for the 3d model.

Once the character design was decided, Franciska began doing the rough storyboard on paper and Marina cleaned the frames digitally.

I used those weeks to do environmental concept art and experiment with blender shaders. I first did some sketches using photo references, then the sketches were used for shots in the storyboard. 

As the concept art we used as inspiration was very stylised, I spent some time watching YouTube tutorials to familiarise myself with toon shaders. 

The above image was made with simple shapes on the left, and the sapling gen addon on the right. While the shaders worked, the problem instead was the structure of the trees as it did not fit with the illustrative style we were going for, as it was either too minimalistic or realistic in comparison to the bird.

To make the 3d environment consistent with the character, I found a ghibli style foliage tutorial and learnt how to create a 2d effect on blender with custom normals and particles.

A tip that was useful in the Ghibli trees tutorial was to duplicate collection instances instead of the object itself for Blender to operate more smoothly. After following the video step-by-step, I tried remaking it again with the leaves modelled. The main issue now is the trunk that did not fit the style of the foliage.

Week 3

For this week, we did further research on the props needed for the environment. We were given advice from one of the tutors to set the garden in a certain location to add more detail, and we settled for an Italian inspired garden. As such, props such as cypress trees, stone paths and orange trees were added to the scene. After doing research and collecting references, Franciska made prop sheet references for interactive props, and I made a prop sheet for the non-interactive props. However, as the prop sheet I made was not stylied, Jin helped to make more stylised versions of the plants, props, and fountains. Marina continued with the storyboarding and Franciska compiled the storyboard frames into a premiere pro file. 

The feedback given was that the stylised props appeared too flat, so we had to find a style that was somewhere between.

We also began experimenting with different colour schemes and styles to make the environment consistent. I tried making a greyscale illustration of the environment with the objects we decided to include in the scene. 

For the tree model, I used the same Ghibli method again but used the sapling addon for the trunk and branches. I also modelled some fences, but it appears too detailed and proportional for the direction we were going for.

As the sapling generated with the addon were too smooth, I converted them into a mesh to manually tweak each branch for a more organic look.

Week 4

In week 4, we worked on looking for a suitable colour scheme that complements the design of the bird. While the colour scheme we chose was aesthetically pleasing, it was unsuitable for the lighthearted tone of the film. As such, me and Jin did more style explorations to find a more vibrant colour scheme.

Daisy also made an expression and turnaround sheet for the character and Franciska made more reference sheets for the environment and secondary characters. I painted a shot from Marina's storyboard for our group to picture what the scene may look like in colour.

I also started modelling the props using the line drawings as a guide. I changed the proportions of the details on the fence to follow the style of the animation.

I tried stylising some of the props, but ended up only using the lamp from these drawings.

The nest and lamp were also modelled, with the nest made using a particle system. On hindsight, I should have used larger sticks for the nest as it looks too detailed in comparison to the rest of the tree.

The props were later textured using a toon shader

Jin also created many of the interactive props needed for various shots.

Week 5

Before Easter break, I added grass to the scene using particle modifiers and drew a simple texture on photoshop for colour variation. A rock path was also added for extra detail. I also changed the colours of the material for an alternate version of the colour scheme. In the end, we chose to continue with the original colour scheme as the greens contrast with the red bird well.

Marina was able to fix the frames which had to be corrected by this week, and Franciska helped to compile everything in premiere pro. As such, we were able to start looking for sound effects. As we were able to finish the tasks on time, we used the remaining time to look for sound effects and background music for the animation.

Continuing from the previous post, I appended the flowers modelled by Jin into the scene and tried drawing a cloud using a Ghibli film still as reference, however the result of the clouds did not turn out well due to the shadows casted by the tree.

Week 6

After the Easter break, we showed the tutors the current progress of our project. Franciska was able to edit the animatic with sound effects and the result was shared. The main issue the tutors had was the timing of the shots and certain camera angles. They suggested the animatic to have longer pauses and the inclusion of more frames.

For the environment concept art, we were told that the garden did not resemble an Italian garden as the tones were not warm enough and we missed certain elements that should have been made to make it loom authentic. Instead, we were told to make it a British garden.

The feedback given for the 3d environment was the textures and length of the grass particles. For the corrected version of the scene, I shortened the length of the particles and changed the shaders of the fence. As the image texture clouds looked off, I also replaced them with a HDRI which worked much better with the environment. The texture of the fence was also changed for the noise to be more prominent as to be more consistent with the rest of the scene. After making those changes, the fixed environment looks like this.

Daisy helped in designing the supporting characters and Jin modelled them with colour variations.

Week 7

As the bird had yet to be rigged, we decided to work on the Previs instead to get the blender files for each individual shot confirmed, making the workflow easier once we began animating. The Previs and animation work were split between me, Franciska, Jin, and Marina. I did shots 1-11, and 36-42. Although we had to add an extra step in the pipeline for a placeholder of the bird model, this was useful in organising the shots and setting up the camera angle.

Week 8

The Previs was complete, and Franciska helped to create a side-by-side reel to check the timing of the shots.

For the animation, the work was also split between the four of us as shown below, with my section marked in blue.

The bird rig was also sent to us, however there were some problems with the eyes. I eventually realised the main problem was with the modifiers, as the mirror modifiers were not applied before the model was sent to Molly, and the separate eyelids were hidden so it was not moving with the armature, but there were still some issues with the hips and joints so we spend most of this week on shots that require little to no change in the bird's movement.

Week 9

By this time, the rigging of the bird had been fixed and we continued working on the animations. As the time taken to render the shots was too long, our tutor Paul told us to render the viewport animation instead to review the entire animation rather than individual shots. This was my personal favourite shot as I didn't expect the animation of the eyes popping out of the binoculars to work.

After most of the shots were animated, Franciska compiled all the viewport renders onto the animatic which was then reviewed by Paul. He gave us feedback on the timing and camera angles of certain shots, as there were a few continuity and flow issues with the scenes. Once those shots were fixed, we began fully rendering the project.

However, the main thing that disappointed me was the rendered grass particles as they looked different from the viewport. I assumed the grass particles looked okay through the material and rendered view and proceeded to do the Previs with the viewport render. The main problem was how it looked in the actual rendered scenes, as for some reason it appeared more rigid and unnatural with many objects clipping into each other. As I had already uploaded the file as the final environment and everyone had completed their section of the Previs, it would be unfair to fix the environment and make the other members redo the camera and object placements.

Week 10

The last week of this unit went smoothly, given we chose a simple story and had an effective production pipeline. The key issues we had in the final lap was the rendering quality of the shots, as we had to redo most of the renders to a 4k resolution to reduce the number of artifacts in each shot. Given that we decided to render everything in a large resolution, it took much longer than expected. This also made me realise how badly optimised the main file was since there were too many calculations made outside the camera view that were still being processed in the render. Fortunately, we did manage to render all the shots before the deadline and Franciska helped with adding post editing effects as well as the transitions.

Overall, I am thankful to be put in a group of people who have vastly different skills and worked in the areas we were strong in. Marina helped to lead out group not only by doing tedious portions of work such as the storyboard, and making sure that we stay on task and meets the goals of each week. Franciska contributed a lot in the planning stage of the production through the prop and character sheets, then helping us with her great expertise in 3d software and video editing. Jin gave us unique ideas in stylisation and modelled many of the props that needed to be interacted, with incredible attention to detail. Daisy also helped in giving us the idea for the story itself and created many 2d illustrations that gave life to the characters.

I hope to do more in the early stages of production such as storyboarding in future projects and will learn from the mistakes I made this time to create a better quality work for my groupmates in the future.

Creative Research

For this unit's creative research portion, we were given a lecture on researching objects. There are varied reasons to research an object and a general definition of an object in this unit's context. The idea that objects are “relational” guided me in understanding this topic as strong storytelling could be done through the physical items. After each lecture, we were also given time to discuss what was covered through seminars. I found the seminars to be useful in helping me understand the content of the lectures at a better level, as well as allowing us to develop our own opinions about what was taught.

A lecture that helped me greatly for my research topic was about researching makers. This was interesting to learn more about as the discussion about the "Death of the Author" has been prevalent on social media, and learning different ways to perceive a creator's authorship of their work especially in collaborative media, as well as the importance of being critical towards the actions of a maker.

For essential readings, the few that stood out to me as engaging and eye opening. Ursula Le Guin's 'Carrier Bag Theory of Fiction'. gives a unique perceptive of fiction that I had yet to consider. The idea of fiction as a "container" and the "botulism" of narratives stuck with me throughout the discussion. Edward Said's 'Orientalism' also made me more aware of the level of otherness which is placed involuntarily of those from different cultures and ethnicities, and is also an informative reading due to current tragedies of the world and the global reaction to the situation. These seminars and lectures have genuinely helped me in analysing the texts I read more critically and these skills would be useful not just for school essays but with the media seen in everyday life.

After the weeks of lectures and seminars, the topic I decided to choose was the production behind the Spider-Verse films. This topic interested my greatly as this franchise had one of the greatest impacts on me as an aspiring artist, and I distincly remember the disappointment I felt hearing about the mistreatment and harsh working conditions behind one of my favourite sequels and films of all time. I ended up using a lot of online articles as research as I found those to be the most useful in obtaining direct sources from producer interviews and recounts from the production staff.
