Basic Information of this project
Project name: Blood Flood
Purpose: The work uses exaggeration and association to present a series of states of human beings after taking drugs, and the purpose of the work is to exhort human beings not to take drugs.
Critical Thinking: Reflection on contemporary human and some national policy attitudes towards drug use by people of all ages; reflection on the place of “opioids” and “secondary drugs” in society and their relationship to human society.
The name of this project is Blood Flood, a short public service film, or advert, about drug rehabilitation. At the beginning when I decided on the theme, I was going to create 4 short stories to express the theme, but Klaus said it would be too long and the audience wouldn’t know the point you are trying to make, so I shortened the story to one clip, here is the storyboard of my initial design.
Since I’m going to create this project through Houdini’s fluids, I’ve collected a lot of related tutorials as well as effect videos. My favourite is the following one
In terms of workflow, I still use Figma for integration, including my mind map, part of my workflow, and some reference images. And this time I will also record some of the difficulties I encountered in the project in Figma, so that my work will be completely based on this software, which will have a great effect on the speed of work!
Here are some reference images I found in the pre-production for the visual effects
Those four images are the most important reference images for me when I create a body of water in the later stages of the process
In making it, I first tested the particle simulation using the nodes on the Houdini tool rack, and added some 3D model to test the buoyancy (although it wasn’t used later)
Next, after testing, I attempted to make a 3D model of the tunnel myself (at this point I hadn’t decided on the details of the shot, so I made a small tunnel to test the fluid first)
Next, I imported the model into Houdini and added it as a collision body and converted it to a smaller model (which makes the calculations faster), then I added the emission source at the end of the tunnel
After updating my tunnel model the water flowed properly, I omitted a lot of parameters on this side, in fact I spent a lot of time on tweaking them, all parameters need to be adjusted one by one. For example, the particle emission density and the gravity (if gravity is not added to the x-axis, it is difficult for the water to flow from the back into the tunnel).
