Sheeter is needed to create the tendrils after the blood emitted.

The default value is 0.1 but I find it to be slow down the emitter too much so I used 0.01. Keyframe it appropriately for high-speed shot.

Drag Force add drag to the blood so it doesnвЂ™t travel with zero resistance.

Quick description of the listed Daemons above:.

Before we start the actual simulation, letвЂ™s refer to the following diagram for the list of Daemons that I used:.

I usually use a value of 0.1 for Ring Ratio. Higher V/H random means more violent burst.

Position the emitter to where the blood need to emit from (e.g.: sliced wound from katana, gunshot impact, etc).

The blue label shows the required changes from the default emitter value.

Use the following settings as shown in the diagram.

I use the Circle emitter for my blood sim in Gantz: O.

Create a standard SPH particles emitter.

Getting startedДЇor the production of Gantz: O, every shots have their own unique blood sim which means I canвЂ™t reuse the same sim for other shots (heh) and if possible, make sure to have your own characters/creatures animation exported to RealFlow.Дownload the project files here (RealFlow 2014).

This ensures the blood that you see in RealFlow is exactly the same in Maya once you imported the blood mesh. To keep things simple, we donвЂ™t need to worry about scene scale conversion as majority of the shots are done with the default scale for the respective software.Д®xport Characters and Background (Maya with cm unit) -> Blood Simulation (RealFlow with m unit) -> Importing generated Blood Mesh from RealFlow into Maya This means we need to export the necessary data from Maya to RealFlow and vice versa.

Maya is the primary software used in production and the scene scale was set to Centimeter (cm) and RealFlow uses Meter (m) as the default scene scale. Make sure that you know the scale of your scene setup as RealFlow internal scale system differs from 3ds Max and Maya. If time permits, IвЂ™ll be updating this tutorial on the look development of the blood aka material setup and rendering using Vray and compositing in After Effects/Nuke.

Quick glance on importing the BIN mesh into Digital Content Creation like 3ds Max or Maya.

In-depth explanation the blood creation in RealFlow (setting up SPH emitter, meshing, cache and graph editor).

IвЂ™ve noted down the necessary settings that one need to modify to shape the blood and the simulation variable depending on the situation. Well there is an in-house blood asset BUT it is really heavy to sim (on a Intel Core i7 3930K 3.5GHz) and this prompted me to improvised a new setup that sim faster for faster WIP turnaround for the FX supervisor and director.

While there are many challenges throughout the production that I wish can be handled better, there is one thing that the film are not afraid in showing visually isвЂ¦ blood! Well 3D fluid simulation instead of fake blood.ДЇor this tutorial, the scene file and settings was based on my own personal R&D to generate a blood squirt and slash for the many shots in the film that I was tasked for. With Gantz: O premiering on in Japan, IвЂ™m proud to be part of the production team as the FX artist for the film. Blood FX using RealFlow as seen in Gantz: O
