phoenix fd foam tutorial

Bubbles larger than Size rise faster and smaller bubbles rise more slowly. This page provides a tutorial on creating a Ship in the Ocean simulation with Phoenix FD in 3ds Max. So, select PHXFoam001 and check the particle systems list. This will generate additional vertices for the infinite ocean mesh for each pixel of the rendered image which makes it possible for the Phoenix FD Ocean texture detail to come through. If the value is set to 0, they will behave as individual points in empty space. Those 2 parameters control the Phoenix FD algorithm responsible for generating foam patterns over the liquid surface. It forces a proper distance between the bubbles and keeps them stuck together. }); Set the Foam Amount to 0. Furthermore, the motion of the secondary particles will match one-to-one when you decide it's time to restore the container back to its original size. This will automatically set up the link between the foam particle group, the shader, and the liquid simulator. The Scattering parameter should be set to Approximate&Shadows. Create a Phoenix FD Liquid Simulator and position it such that the front of the ship is close to the +Y wall of the simulator. .rwui_id_e387a3ab-5b40-4a1e-a4c1-f9eb476f7e8b {color: #666666 !important; background: rgb(237,237,237); border: 1px solid rgb(201,201,201);}.rwui_id_e387a3ab-5b40-4a1e-a4c1-f9eb476f7e8b:hover {border: 1px solid rgb(166,166,166); background: rgb(219,219,219);}.rwui_id_e387a3ab-5b40-4a1e-a4c1-f9eb476f7e8b .rwui_icon {color: #666666 !important;} Download Project Files. The sun is positioned relatively low on the horizon to produce yellow-ish illumination that is balanced by the blue lighting provided by the VRay Sky texture. Learn how to create popular simulations with Phoenix FD for Maya. Your browser does not support the HTML5 video element This parameter controls the distance between the copies. Overview This is an Advanced Level tutorial. /*]]>*/ if (newScrollPosition > lastScrollPosition) { If set to 0, Liquid particles are NOT killed when generating Splash particles, and Splash particles are NOT converted into liquid when they enter the body of water and die. Proceed by creating a Phoenix FD Liquid Source and specifying the box_liquid_source geometry as the emitter. Reply … Reflect and Refract colors should be set to white - this will produce a completely transparent material if the Index of Refraction was set to 1 (which is the IOR of clear air). However, keep in mind that you may want to increase it if the vessel you're using is moving faster. .rwui_id_35662878-e79c-47d5-9771-9fd86493fb48 {color: #666666 !important; background: rgb(237,237,237); border: 1px solid rgb(201,201,201);}.rwui_id_35662878-e79c-47d5-9771-9fd86493fb48:hover {border: 1px solid rgb(166,166,166); background: rgb(219,219,219);}.rwui_id_35662878-e79c-47d5-9771-9fd86493fb48 .rwui_icon {color: #666666 !important;} Download Example File. V-Ray Frame Buffer Color Corrections Not doing so will cause the box to become an obstacle to the fluid and thus the particles inside it will be killed because it's Solid by default. The Splash Amount controls both the size of the splash particles and their number. The foam born inside the Birth Volume can travel outside the volume without a problem. jQuery('#tocHorizontal').hide('fast'); [CDATA[*/ All you need to do is select a Particle Shader and use the Add button at the top to include a particle group to the Particle Systems list. The Ocean Level might not exactly match the Initial Fill Up level, even when set to the same value, and you will notice such mismatch right at the boundaries of the Phoenix FD Simulator where the generated infinite ocean connects with the simulator's liquid surface. Splash Threshold 3, Your browser does not support the HTML5 video element Your browser does not support the HTML5 video element Depending on your machine and the resolution of your sim, this option could provide a decent speed boost. } lastScrollPosition = newScrollPosition; ven though a real-life foam bubble is obviously not 5cm wide, here we can afford to use larger and fewer foam particles (because this is a distant shot) in order to optimize the sim. This includes foam born according to the conditions set by the Foam Amount and Birth Threshold parameters of the Foam, as well as the Foam on Hit parameters of the Splash. Invisible is enabled so the sun does not produce noisy specular highlights over the ocean's surface. Also note that the longer the trails are (the higher the lifespan), the more bubbles will accumulate during the course of the simulation - this has the potential of slowing things down and consuming more memory. Your browser does not support the HTML5 video element Note that this is not the time since the particle exited the grid, but the time since the particle was born. The Foam Lifespan is your main control for the length of the foam trails to the side and in the back of the ship. It may be hard to notice when the Outgoing Velocity is set to a low value so check the example videos below. In this tutorial, the Foam particles that generate the trail of the ship are created from Splash particles. The ship in this example is already animated for you. Your browser does not support the HTML5 video element Go to Customize → Units Setup and set Display Unit Scale to Metric Meters. And even if I increase the ocean subdivision it takes ages to calculate and it still looks bad. Let the entire simulation cache to disk. We also take a look at an advanced setup allowing you to simulate multiple vessels in separate Phoenix FD Simulators and merge them into a single infinite ocean at render time. You can find the VRay Sky texture in the Hypershade. Max Outside Age | foutlife – If a particle is outside the grid, and its age (in seconds) exceeds this parameter, the particle will be killed instantly. V-Ray and the V-Ray logo, Chaos Vantage and Chaos Vantage logo, Phoenix FD and the Phoenix FD logo are registered trademarks of Chaos Software OOD in Bulgaria and/or other countries. Here's how a rendered image looks so far. #1 3Ds Max & Phoenix FD Tutorial - Fluid Simulation, Beer Animation by Edge-CGI 3D Tutorials and more! From the Coordinates tab of the PhoenixFDOceanTex, you may change the Angle Z to a value of your choice. The Falling Speed is also affected by the size of the individual bubbles. Splash Threshold 10. Here's why this is needed: the Fog Color parameter of the V-Ray material won't affect the Phoenix FD Particle Shaders (with a Liquid Simulator connected) unless the 'volume' of the liquid is capped. This will automatically set up the link between the splash particle group, the shader, and the liquid simulator. The Phoenix FD solver is not affected by how you choose to view the Display Unit Scale - it is just a matter of convenience. You can convert the geometry to a non-solid from its PhoenixFD properties. Wikipedia tells us that the length of the ship is 154 meters. This process is controlled by the Affect Liquid parameter at the bottom of the Splash/Mist rollout. If set to 0, Liquid particles are NOT killed when generating Splash particles, and Splash particles are NOT converted into liquid when they enter the body of water and die. The Liquid → Splash → Liquid example above is correct only in case the Affect Liquid parameter is greater than 0. Your browser does not support the HTML5 video element The particle shaders for the Foam and Splash particles have less than ideal settings for this particular scene. As the focus of this tutorial is a large-scale ship simulation, setting the units to Meters seems like a reasonable choice. This change will give a smoother appearance to the foam particles - the lower Alpha value will allow them to blend together and also reveal some of the liquid underneath. create a V-Ray Plane and place it below the Ocean Level. Feel free to also copy any additional geometry that was linked to ship_geo_001, such as the propellers. Phoenix FD; Phoenix FD :: Issues; If this is your first visit, be sure to check out the FAQ by clicking the link above. Your browser does not support the HTML5 video element As a side note - you can edit the Frame Rate from the Time Configuration window whose button is right next to the Set Keys button in the bottom right. The Phoenix FD Simulators should be seamlessly merged together. The following video provides examples to show the differences when Variation Small is set to 0, 1, and 50. If you hit render now, you will notice that the entire scene is too warm. }); Consider the simulator size required by a meteor flying through the air or a ship sailing through the ocean - the simulation time and memory requirements of a simulator spanning the entire path of the object would be enormous. By default, the birth volume geometry is not automatically converted to a non-solid and it will behave as a rigid body in your simulation. 34:32 . The time required for the particles to reduce to half of their initial count, in seconds. 22-11-2020, 03:31 PM : Phoenix FD Maya by Avesani. The difference between this approach and spawning foam inside a volume manually from a Source object is that using a Birth Volume, the foam birth will follow the simulation criteria of the simulation and will look and behave more naturally. Foam Amount | fbirth – Specifies the number of particles to be born when a given cell meets the birth condition, in thousands per second. If possible, make sure that the bounds of the Phoenix FD Simulators do NOT overlap. X amount of liquid produces Y amount of splash particles. The Light Cache Speedup can significantly reduce the render times. Rate this: Share this: ... Hybrido Lighthouse Liquid Liquid Simulation Maxwell Maxwell Render Mental Ray Ocean Ocean Simulation Particles Phoenix FD Phoenix FD Foam Phoenix FD Liquid Phoenix FD Splash Phoenix FD Tutorial Phoenix FD Tutorials Phoenix FD Water Phoenix FD Waves Polygons Realflow RealFlow 5 Realflow Fluid Realflow Foam … Phoenix FD is an all-in-one solution for fluid dynamics. Affects only the foam bubbles above the liquid surface - those inside the volume will not burst until they reach the surface. With emitter at the back of the ship. The following video provides examples to show the differences when Rising Speed is set to 0, 20, and 100. Determine the length of your simulation. Do the same changes to the Phoenix FD Splash shader. Set the Splash to Mist parameter to 0. With Liquid Source at the back of the ship. Consider setting the Read Cache for Preview option to Disable During Sim. So Y amount of splash particles is converted back into X amount of liquid. Example: Birth Threshold Birth Threshold | fbthres – Foam is born where the liquid movement is turbulent. B2B 100 + Foam Size 0.3 + Pattern Radius 6. Logged 2020-10-09, 22:55:22. 10 means that the smallest bubbles are 11 times smaller than Size. If you'd like to have greater control over the foam trail at the back of your vessel, the most straight-forward approach would be to use this exact same technique mixed in with a different Outgoing Velocity, Modifiers, Texture maps for the Outgoing Velocity, or even using the Noise parameter of the Phoenix FD Liquid Source. Phoenix FD Tutorial Series by RedefineFX. However, that may not be the case with your ship or boat so let's see how to go about fixing this. The Size options in the Particle Shader allow you to edit the Foam particle size after a simulation is complete. When I switch to V-Ray 5, it show the texture then, but when I switch to Corona it disappears. Unhide the original ship (ship_geo_001) and the original simulator (PhoenixFDLiquid001). Open the Foam rollout and select the Enable checkbox. In real life, the liquid at the back of the ship is pushed backward by the propellers. Open the Point rollout of the Foam shader and set the Point Alpha parameter to 0.017. The scale of the option is in units/sec. Increase the Outside Life parameter. All • Liquids • Fire & Smoke • Destruction • Product Animation. The Phoenix Difference Phoenix FD is the only fluid dynamics plugin that allows you to create water simulations with splash and foam entirely within 3Ds Max All-in-one solution to create water FX start-to-finish, including meshing, particle rendering & infinite oceans. Droplet Surfing is your main control for the width of the foam trail. To start viewing messages, select the forum that you want to visit from the selection below. The workflow for setting up the shot, and the Phoenix FD settings involved in the simulation are explained in detail. Birth Volume | usefbconfgeom, fbconfgeom – When enabled, allows the foam to be born naturally by the simulation only inside a specified geometry object. As you can see, there are several things in regards to the shading that need to be taken care of. UI Path: ||Select Liquid Simulator | LiquidSim object|| > Modify panel > Foam rollout. Multiple Ships Setup However, this trick is a huge time saver so consider incorporating it into your workflow. In the second case, if the Falling Speed is too low, the foam might abruptly slow down at the moment it separates from the liquid that carries it. Emitting Without Polygon ID specified and high discharge, Your browser does not support the HTML5 video element Phoenix FD is used in multiple television series such as Game of Thrones and The Flash, and is specifically designed for fast-paced production. Simulation with Final settings at 5M Cells, Your browser does not support the HTML5 video element The scale of the option is in units/sec. The Ocean → Ocean Level parameter needs to be adjusted as well. When prompted with the Clone Options dialog, select Copy and hit OK - the copy should now appear below the ship geometry and should be named PhoenixFDLiquid002 (if you kept the original naming). This may take a while depending on the speed of your machine. You may want to edit this parameter depending on the type of vessel you're simulating. If the difference in velocity between two neighbor voxels is higher that this threshold, foam particles should be born. You can force this process by increasing the Rising Speed. Online licensing option now available. The foam may be born from the liquid, splash droplets, a Source, or a script. If the included particle system is called PG[, Add the corresponding particle group of PhoenixFDLiquid002 which, by default, should be named PG [. In this example, we generate the Foam from the Splash particles using the Foam on Hit parameter in the Splash/Mist rollout. In this case, the, can be used to expand an area around the object where Foam/Splash births are possible. Example: Falling Speed Set the Size to 0.05m. You should now have 2 ships in a single ocean, with all the secondary effects rendered as well. The motion and behavior of the secondary particle effects (such as Foam, Splashes, Mist and Drag particles) can vary depending on the resolution (Cell Size) of the Phoenix FD Simulator. Be sure to leave some extra space at the back of the ship - that way, the foam generated by the ship as it travels through the water will spend enough time inside the simulator to form interesting patterns. 1-3 subdivs should suffice for most setups when rendering at Full HD 1920x1080. div.rbtoc1610235855384 {padding: 0px;} Phoenix FD is the all-in-one fluid dynamics plugin for Maya. }); Instructions will be sent after purchase. Note that bubbles inside the liquid volume are carried by the velocity of the liquid, and also affected by this parameter. However, creating a production quality shot of a similar nature may require some tweaks to the lighting, materials and/or the Phoenix FD simulation. Splash Amount 10, Your browser does not support the HTML5 video element The Motion Blur Step is set to 1. The Particle Tuner in the scene is used to increase and randomize the viscosity of the lava over time. New! Please check the comparison playblasts below. This is controlled by the Ocean Level parameter and it defaults to 50. jQuery('#tocHorizontal').show('fast'); For more information, see the Rising Speed example below. This parameter controls the behavior of splash particles in the air. That is all. In this case, the Volume Fadeout can be used to expand an area around the object where Foam/Splash births are possible. //]]>. In this example, an Initial Fill Up level of 25% is sufficient. Simulate realistic fire, smoke, liquids, ocean waves, splashes, spray, mist and more. In most cases, this parameter is used together with the patterns generator. /*
