Collaborative Project Progression

We have completed a part of the project excellent. I am sure that in the constant exchange of ideas, each member of the group learned something new, and in particular, I learned many key details from the whole project. I kicked off the whole project with the main idea but a lot of the details were perfected by my team members. Even though we had dovetailed most of the workflow in advance, there were still unexpected errors. For example, when the modeller packaged the entire project file for me, I found that I couldn’t merge the two project files. When I select my project file, I cannot open the Maya file in another project file properly because there are errors. These errors cause the mapping path to be missing and the reference file to be missing. Another problem is when the animator copies the file to me, if I then delete some polygon, the reference file is automatically invalidated and cannot be read correctly when I open it again.

I also learned a lot of new skills through this project, such as some Houdini effects.

To practice the houdini particles and fabrics section, I made a small demo to familiarize myself with the different panels of houdini. In addition to special effects, I also practised parametric modelling.

In addition to this, I also practiced volume and fluid.

Because one of our group members dropped out, I needed to learn an extra part of the fabric and solve fabrc. At first, I planned to finish the model in MD and then solve it in Houdini. It turned out to be too expensive to learn in Houdini and all the fabrics were done in MD.

This week I learned somethings about the foundation of green screen. Some basic information about selecting the specific areas in different ways. We have learned about luminance, saturation and hue. The main idea of the colourspace transfer is similar with the colour lab in photoshop and so on. In addition to this, we learned some simple techniques to process different channels to obtain a specific areas through basic arithmetic.

This week we are asked to roto the machine sequence. I have tried both two idea to get a correct alpha.

One of the method is easier. Only using a certain fix frame to project it on card which is at a correct position and we can get a property result by a correct render through a tracking camera. Another one is a little complex I use two project node to finish it. I think the both two way have been told in two weeks ago, so I did not explain too much here just post a screen-print.

This week we have learned how could we combine different layers from certain render. I have used v-ray, Arnold and mantra render. So It’s not difficult for me to mix different AOVs. Once I understand the principle of render each step will be more clear.

Besides that, Mr. Gonzalo has showed us the function of utility textures such as Position, Normal, Depth and so on. Although, some utility textures’ name is different in different render, the main idea is similar. We can use them to rebuild light or make a Len’s effects.

This week we have learned more examples about the project node. In certain statistic building scene it is a really fast way to patch or add something in images by the project node. We mainly learned two interesting ideas to come true some amazing results. Firstly, we can use the project camera to map certain frame information to realistic space coordinates in the nuke 3D view. Then we can operate what we want in the single frame and use the tracking camera to render the whole images again. Finally the patch elements will be automatically catch to the moving. However, a issue we have to focus on. Almost all ideas can skip the frame hold node which means we the patch area is just a single frame and we only use one single information to cover the whole sequence.

Another idea kinds solve the problem. We used the tracking camera to map the whole sequence to the realistic coordinate. What will happen then? We can collect and fix the whole information of a certain object. The result is that certain object color information will be limit in a fixed position in nuke 3D viewer. We can use certain great frame to render a cache image and change anything we like at the same time. Finally, use the tracking camera to render the finally images.

This week, I have rendered all factors in the Arnold render. I used three rectangle light to make the shadow of the old machine catch the raw sequence. one more important thing is the color space. When the rendering finished the default color space is srgb, we have to change the setting in nuke same as Arnold.

I have finished textures in the week. After updating the substance painter to newest one, these is something changed. Especially for different materials in one model, it is a little wired to split them into different parts to paint. Besides, there is some problems for baking AO and normal textures. Sometimes I don’t want components to affect AO textures each other, I only want to them to affect themselves although I use different color to control area, the result is not perfect and it also take much time to try. So although the substance painter is a easier way to finish textures, the workflow is not clear and the software can’t support Arnold materials well. I have to transfer them to Maya standard material such as Lambert material. The utility textures is really helpful for smart material which can save much time, I hope the Adobe will improve the workflow in future. And another problem is applying textures in maya. I have to import each textures what I have finished in Substance painter. When the the number of objects is large, reapplying same result in maya is a crazing work.

I export tracking camera information to Maya scene from Nuke. The first time test is not good because I notice that the scene cannot catch the models. I found the tacker point is not as much as good. After I delete some useless point it work well. Then I adjust the position of model to make it have a correct angle and make it look good.

I have talked several times with my animation team member to improve the rhythm of the animation and fix some problems.

at the same time, I was prepared to solve the flip in Houdini.

This week We finished the p1c3,p1c4,p3c3 animation and We are going to finish p1c2, and p4 animation. My partner YingYue Feng and I always talk how could we improve animation detail such as blow. Because we have an extreme close lens for the foot, we have to handle the toe rotation well.

Because one of our members quit our group, we need to share her jobs such as the clothe and some visual effects about clothes. I am designing new clothes for the girl because the old version almost can not be used. Before that, I also found some problems with skin weight and I start to solve them.

To save resources I delete some parts which is not in the camera view.

In a word, we continue to communicate deeper for the animation of the character and fix the tiny problems this week. The model art starts to build environment objects to make the scene rich. Everything is going well even we lose one partner I trust we can handle the project.

In the third week, we established a very detailed production plan and a division of labour among the group members. We also discussed and decided on the content of the footage we needed to produce.

P1c1: Medium shot, the camera panning to follow. The view follows the leaves as they drift down and finally land on the tip of the lance.

P2c1: Close up, the camera fixed. The lance is awakened and activated, starting to shake and vibrate.
P2c2: Panoramic view, camera surround. Panoramic view of the lance as the whole lance is surrounded by the hostile aura of the soul
P2c3: Close-up, camera fixed. The heroine’s feet splash against the water as she runs past

P3c1: Panorama, the camera panning to follow. The heroine runs towards the centre of the scene, right hand raised, lance in hand.
P3c2: panorama, camera pans to follow. Part of the heroine’s gun dance.
P3c3: Close up, the camera pans back. Lance flying up ready to articulate the special scene.
P3c4: close-up, camera pans forward. Lance drops down for the scene to the memory section.

This week I also finished modelling the trees in Speedtree.
