07A | Facial Emotion

Result

This week I set keyframe for all mesh to the final design of each emotion. However I haven’t confirmed with the motion yet. Therefore, it is a result for some screenshot for each emotion first.

Original face

Angry face

Sorrow face
Fake smiley face


Work In Progress

Rigging and paint skin weight

Do you know how much muscles involved in one single smile ?
According to howstuffworks.com :

If we look at a smile that only raises the corners of the lips and the upper lip, it takes only five muscle pairs, or 10 total muscles, to do so. However, if the smile is further reduced to a robotic expression of just raising the corners of the mouth, then it takes only two muscle pairs (four muscles) to smile.

Therefore, I believed the smile facial expression is the most challenging facial expression to animate. The geometry for this model is not quite enough for me to adjust the minor expression.
In human being interaction, insincere smile can quite easy to identify by human being. That is our nature to read others facial expression for us to interact with others in this nowadays society. Therefore, the animation to modify a sincere smile is the most difficult one. I am not satisfied with my result, but I think it is a good start for me to improve my animate skill as character design is not my familiar subjects.

Reflection

For me, controlling the paintweight brush is quite challenging. Sometimes, my brush was not accurate enough for me to paint the skin area I targeted, and in turn it made me spend loads of time to smooth for a blurry area between and black and white area.

Next step, I would like to animate them in one final showreel to show all emotion. In this way, I can demonstrate how the rigging and shape editor helps me to animate the model.

02 | Nuke Color Match

With my previous experience of using Aftereffect, it needs time for me to adjust while using Nuke, even sharing the same concepts within both softwares , or even among all other compositing software, the keywords and terms in Nuke are seems to be strangers to me.

The things to remind myself:

  1. Gain and multiply – highlight control
  2. Gamma – midtone control
  3. Lift – shadow control
  4. Toe – black control
  5. BlacksMatch – a gizmos for black control

Another obstacle is my aesthetic skill on coloring. While I need to eyeball the color of background and the object to finetune and match them. All I can say is that, somethings are not right yet, the airplane is still a “fake” one, it didn’t merge with the environment, but I don’t know which buttons to adjust my discomfort for the color.

Figure 2.1 – The node graph of this color match classwork
Figure 2.3 – The work in progress of the color matching.
Figure 2.4 – The top one is cloud png without premult node, and the bottom one is with premult node.

And when I first input the cloud png into the script, the edge of the cloud was so rough that I misunderstood Nuke cannot recognise the alpha pass. But then I discovered that what I need is just a premult node, as we don’t need this step in aftereffect, I definitely need to solid my knowledge with the concept for premultiplication.


Result

Figure 2.5 – The result of my classwork, color matching for a airplane with the sky environment.

That is the best result I can gather, but I am still not satisfied with the color match. Somethings are still not right by my eye judgement.

01 | Nuke Roto

Result

I am not satisfied with the result, still a lot things to learn. I think I should not put all my roto in one single roto node. I should separate them into several nodes for better organization and less chances for distorted roto mask.


Work In Progress

It took me nearly 7 working days to finish this task, which is way more complicated than my expectation. When I struggled in working with all these chaos, I also did some researches of tips and suggestions for Nuke newbie on YouTube. This, in turn, allows me to find inspiring tips from YouTube creator, Hugo’s Desk, which explained how to do roto in Nuke quite clearly, and the most useful tips from him is to keep on hardworking in roto. No secrets, no magic, just hardworking.

My roto became a disaster !!!

As the footage is a jpg sequence that not much details for me to do a pixel-perfect roto. I am not able to see the hair shape to define the roto, even I adjusted the gamma in my viewer, still I can’t identify the edge of my matte.

Still, it is my first rotoscoping task in Nuke. I will keep it in my mind to apply what I have learn for further rotoscoping.


06b | Rigging and motion

Result

Figure 6b.1 – Classwork for picking up a ball

Try to imagine what would you do with a lost item, such as a wallet on street?
In reality, it is expected that pedestrian will pick it up cautiously with head turning to look around for its owner. However, in my character’s design, adding exaggerating body language to present his personalities, tipping toe to look around, and holding his arms on waist while observing the object, communicate to my audience with his personalities,
eg. conscientious and inquisitive, without a word of dialog. Being extreme is a way for me to follow the animation principle (Figure 6b.5) and add excitement in the motion for audience to understand my character.

With adding animation principles as below.

Figure 6b.2 – Version 01 – Pick up motion

Figure 6b.3 – Version 02
– Pick up motion with object followed, character staging and secondary action on his left hand.

Figure 6b.4 – Version03 – Adding exaggeration to show character personality.

06 | Maya Keyframe

This week, it is the classwork for animating two types of weight, hard ball and soft ball in Maya.


Image source from The Animator’s Survival Kit

With The Animator’s Survival Kit, every animators know bouncing ball on floor depends on spacing and timing. However, when it apply on stairs, I have to implement the textbook knowledge into practical situation.


Result

Hence, loads of eyeballing adjustments of work in this classwork, which I can hardly descript in written English. I observed my ball in loop play, and somethings were still not right to my eye. After over and over, finally this result is the most acceptable version as the types of weight can be easily identified between hard ball and soft ball.

05 | Modelling in Zbrush

First male head modelling in Zbrush. I think there are too much “fingerprints” on my male model. And I made it look like an elderly, which is not my purpose. Jaw line is not obvious and it is not masculine enough.


Second male head modelling in Zbrush after reference from Youtube channel SpeedChar : Proportions and shapes of the human head in 1 hour

I think I am satisfied with this result and I am ready for the next step, painting on his face and skin texture.

Genres identification

Week6 – short comparative analysis of two comedy movies.

Genres is the catalogue of movies. When we divided movies into genres, it is easier for audience to expected what elements will they see in the movies, as there are certain amount of elements in common within a single type of genre. Nowadays, the boundaries between each genres of films are quite vague, and it can be further defined as “sub-genres”.

In this analysis, the following two movies demonstrate what comedy genre is, as a general genre for audience to expect.


Cambridge Dictionary defines comedy as 

a type of film, play, or book that is intentionally funny either in its characters or its action”

04B | Final Kitchen Scene

Result

Maya was the software I had used it around 5 years ago, and I shifted to Cinema4D for a while, as I thought the Maya default render engine didn’t perform well even if I put so much efforts in it. However, after all these years, with Arnold renderer, I am quite surprise with its rapid respond and excellent performance. Despite Maya still crashed for tiny things sometimes, I think I feel more confidence to work with Maya again, as Maya is still the major 3D software in VFX industry. I don’t think there is any reason for me to not work hard to overcome it.

Finally, after weeks, all assets were put into the kitchen scene. What a nice kitchen dinning area for two! I am glad I did it!

Still, for these kitchen scene, I am not satisfied with the texture of cupboard, curtain and fire stove. The wall is too rough as well. Too much exposures around the windows. Loads and loads of things I can keep on complaining. However, within this period of Term 01, I have trained my finger muscle to get use to Maya. Moreover, I’ve kept myself focus in details with aesthetic judgement, which I think it is another endless topics for every artists and designers in this ever-changing industry.

04a | Spoon And Cupboard

It is a classwork for practising modelling and texture. Also, I learnt how to use maya camera to frame one single frame to output a snapshot.

Result

I think the noise for this scene is way to much, but lighting is quite easy to control. I only used three points lighting for my objects, especially for the glass bottle, the Arnold render is way more qualified than my expectation. Comparing with my experience a few years before, I only used physical render for my output, which is much more time-costuming.


Work In Progress

Then, I would like to add a metal spoon on table.

I would like to add this cupboard to my scene, some details have not decided yet. But I think it is a good practise for me to deal with Maya software, as it is not same as Cinema4D, even some concept may be familiar but I need to train my finger muscles to do all the shortcuts correctly.

First Step of everything

With the experience I have gained so far in my journey to become a motion graphic designer in Hong Kong, I am getting more aware of the skills and knowledge that I would like to improve on. With my education background majored in Digital Media, enabled my design thinking process to mature in all-round aspects, I would like to get involved in VFX industry and become a digital compositor.

From gathering insights through pre-production brainstorming to presenting final rendering, VFX is a pathway built for people to reflect on social media culture, immersive entertainment experience and virtual reality technology. Beside software skill, film language is of utmost important for me to communicate with my fellows in the industry. Furthermore, with the research I am going to study, I am able to absorb all masterpieces of works from the industry predecessors, with proper guideline from my tutors in this master degree programme.

Under this line of thinking, I might tended to research on animation, motion graphic study, or Disney culture, etc, as I suppose they are the major influences for all kinds of entertainment industry in worldwide.
