We were asked to choose what we wanted to do from the images given to us and then process it to turn it into a video

I choose this one:

Because I really like the scene where the items are all stacked up and the lighting in this scene makes me feel mysterious. So I’m going to turn it into a scene where magic and reality intermingle

I have roughly designed the arrangement of the items

The problem I now face is this.

1. I can’t get an exact camera position out of a picture, and because it’s not a coherent video I can’t generate a point map and camera position. This results in only getting an approximate amount when rendering the cg angle.
2. I need to take into account the effect of lighting and other factors on the cg, which makes pre-processing tricky. I also need to consider whether I need to render each part separately

Our session focused on the specific synthesis process and handling

We reviewed the use of grade for colour grading and how to adjust materials via uv mode. But it’s more about a lot of detailing, so I’ll be putting in more of the process and nodes.

In this lesson we are going to start making loop animations and our teacher taught us the basic usage of mash. We were also asked to design our own loop animation.

I found an animation reference

I have created the corresponding model, but I am having problems with the animation.
I have animated the ball moving around the track using mash, but I don’t want it to move at a constant speed. I want it to move slower on the sides and faster in the middle. But I didn’t find a solution online.

My thought process

I think on a street like this the car is firstly backlit, which causes its frontal reflections to not be too bright, and secondly the orange of its colour would look a bit grey against this kind of cool light and background, so I changed the inherent colour and reflections. At the same time I resized the car slightly and added shadows.

Another job clean up and roto walls

I wanted to use roto for the skeleton effect, but haven’t solved the problem yet. So I will upload a video when it is fully solved.

I solved the problem of how to use roto to make a skeleton mask.
There are two methods

1. make a layer attribute “minus” to the roto of the hollow part
2. use marge to combine the two parts of the roto

My teacher told me that the second method was better because it would allow others to understand my steps better when working on larger projects and would also make it easier to make changes later.

But I still have some problems with my clean up, they disappear in a few frames. I think it’s caused by the card not fitting perfectly into its original position, but I’ve resized the position and size a few times and a few frames will show. I don’t know why this is, or what I can do to create a perfectly fitting card. Because I have used as many points as possible to make the card, but the result is still not perfect.

This lesson focuses on setting up how cg is used in nuke.
and how to manipulate the cg with different lighting materials

We first learned about the different layers of cg and its applications。

We also learnt how to adjust the lighting for the cg

The session was completely done and all the designs were rendered for the materials. But the computer went black when rendering! Hopefully the technician can fix it because I don’t have it on my hard drive!

There is a lot going on in this lesson, which is generally divided into two parts.
A The practical points to look out for in 3d tracing

1. be careful with the frames you choose, otherwise it will be too blurred at some distances
2. you can use the mergemat to combine the materials of the two surfaces, it can have a higher qualit

B How to adjust a still image from day to night

1.Use colour grading

2.Rebuild the 3d scene from the image and adjust the lighting background on it

The teacher was sick so we watched some videos about baking and cameras
