    Robot Droplets Test

    Continuing my droplets tests I created a new workflow within Realflow. First I am creating the micro droplets which stick to the helmet and are the tiniest of drops (these are shown as white in the first picture). Then I add a second emitter to form the big drops. These bigger drops contain particles that tend to stick a little more together with surface tention.

    I then fine tuned the mesh created by realflow. There a several options to control how your mesh looks, you can first set your radius, this determines how big the distance is between the actual particle and the mesh created around it. Since we are having little drops compared to the robot we need a small value. Then I handle the smooth option, this option is extremely interesting in creating drops since this is the option that either decides to merge or not merge the mesh to a neighboring particle. This effect creates the bigger drops that seem to have merged as two individual drops.

    Eventually i exported the mesh into Maya and added a V-Ray material and setup a camera, lighting and HDRI for the background. The result was quite surprising, the shader that I applied to the water seems to behave a bit weird. In the second picture you can see in the top left that weird stuff is going on and that the water drops are black. But you get a general sense of the robot being wet. I later tried to replace the low poly robot with the high poly robot but that didn’t work out that well. Most of the drops aren’t sticking to the face because of the difference in geometry. Going to make new sims with the high poly robot.

    Realflow Droplets Test

    After doing some test last week Remco asked me how the droplets would look like, I went on to test them inside Realflow since it has a simple shader setup and a Maxwell render engine. But it will not have the same effect when you export the mesh and use V-Ray to lighten the scene. That’s why I did this test, It’s like a puddle exploding!

    Robot Droplets Test

    I haven’t posted anything in a while so I’m posting several posts. Last week I was busy creating droplets on the helm of the robot. I’ve discovered that showering the robot in one go and hoping for droplets to be forming is not the way to do it, there is not enough control for that while “showering” the robot. Instead i’m creating droplets by putting a sphere emitter around each individual part and attracting the particles onto the body parts.

    Currently I’m working on the helmet and I can control the size of the droplets much better. I’m trying to get the size right by doing these tests, you have to imagine that the robot’s head is around 1.30 meters wide and 0.84 meters high. More tests are incoming.

    RealFlow Robot Shower Preview

    I continued playing with BiFrost but it didn’t have the necessary elements yet, since it is so young. That’s why we switched to RealFlow, they provided us with a educational setup for the project.

    The water in this sim feels too thick for the robot. So i want to use way less particles. However I am very happy with the stickiness result, the water really is dripping of the robot as intended. Just need to use less particles. Also the particles need to slide less on the floor since it’s tarmac in the real footage.

    Particle count: 444.000
    Simulation time: 03:52:33

    We got Realflow!

    Ok, after a lot of BiFrost tests I came to the conclusion it is not possible withing BiFrost to have a lot of control over the fluids. Since BiFrost is new in Maya 2015 it is still young in development. That’s why we can’t have what we want to have.

    Another solution to our problem would be a highly professional fluid sim called RealFlow. Remco told me just to email RealFlow explaining what this project is about and what we are doing within Saxion, maybe this way we could get a cheaper version of RealFlow since the commercial version might turn your piggy bank upside down!

    One email later I got the response that RealFlow is FREE FOR UNIVERSITIES! Joy oh joy!!! I got a message from RealFlow that the only thing they needed was my student email address and that they would set me up with RealFlow.

    Once I emailed my contact information for my student email address i was setup with a RealFlow Learning Edition licence. They responded within 10 minutes. I was able to download the software from the website and I was on my way.

    So special thanks to you, Dan from RealFlow for the great support and very quick response!

    Robot Bifrost Stickiness Strength Comparison update

    The last Stickiness Strength test was not succesfull, Stickiness Strength alone does less than what i expected. I tested Stickiness Strength from one up to a million in big steps, but no clear result. I am now going to test adding Stickiness Bandwith to it.

    Robot Bifrost Stickiness Strength Comparison

    The water needs to stick to the robot, that is why I created 4 different Stickiness Strength playblasts. I didn’t notice any difference in the first three playblasts so i decided to up the amount drastically for the fourth. The next four tests are going to be huge numbers to see what the difference is. It is because of the scene size that the stickiness has to be so big.

    Robot Bifrost, track and animation

    I’ve learned to animate the robot a bit about a week ago, i know now how to handle HumanIK and how to make basic animations. So in this video you get to see kind of what the end shot is going to be like.

    At first the robot of course needs to be drenched in water, that’s why he is standing still. After that the animation starts. The water needs to stick as much as possible, so that the robot is still dripping in water when animated.

    This is the actual footage and 3d tracked scene. The animations are basic, but Hajir is going to make the animations for the actual end shot. I just needed the basic setup so i can experiment with the water.

    Robot track test

    So yesterday I’ve setup my first scene ever. Toon provided me with the tracking data and Hajir and Ivaylo helped me a lot on setting up the scene. It’s actually quite simple now that i look back on it, but the results that you get are amazing. Once importing the track locators you have one camera that does all the work, attach a backplate to it which contains your footage and you are pretty much done. So easy but very powerful. To make it even better for yourself you can rotate the camera, tracking points and ground plane (which Toon also provides) to the grid of your Maya scene. This way you can create anything on the grid and it matches perfectly (movement wise) in the real footage.
