This collaborative project was very interesting and difficult, because not only did it test my skills of 3D and post-production, but also exercised the communication and collaboration between me and my teammates. My partner and I have encountered some problems in the cooperation process of 3D production.
First of all, the software I mainly used was Maya, and the classmate who was responsible for special effects used Houdini. Between the two pieces of softwares, the conversion and use of assets is an important part of the process. Since the VFX designer needed to create effects in houdini with the assets I made, then he would export the created effects to me to create shots and render in Maya. However, during this process, we have encountered that the exported files from maya are not available in houdini, or the files from houdini are static in maya, or maya will flash back. Especially when we worked on the effects of paper, we had a serious problem. Paper effects files exported by the VFX designer in houdini can not be rendered in maya, and would cause maya to flash back. This was a problem we had for a long time, because we were worried that we couldn’t render the key scene where the fish pushed the paper to the bottom of the pond. This problem would affect the overall plot of the film. We tried various methods, but the VFX designer used a very special way to solve it. He imported this file into houdini and exported it, then I was able to render the effects of paper in maya. However, we immediately ran into a new problem, the new effect’s model did not have uv. I can’t divide the UV in maya because that would make the UV change with the effects. Finally,I transfer and copy UV between two identical objects in maya; as a result, I copied a paper model, then divided the new UV and copied it onto the effect’s model.
Moreover, the visual style of this film is realistic. I spend a lot of time in rendering and post production to create realistic and beautiful images. If I want to do color-adjustment in nuke, I need to adjust the lighting and render settings in maya, especially aov. This is very important because aov allows nuke to get the most out of it to get the best visual effect in the film. I often use cryptomatte in nuke. We need to import the rendering sequence of the crypto object into nuke and connect the cryptomatte. Finally, we can select any object in the frame to adjust the color from this node. Because there is no guarantee that every object will get the best rendering effect, we need this method to adjust the frame of the film. This collaborative project is meaningful for me. If there is time later, I hope I can improve the parts that I am not satisfied with in the film.
