Octoplug Ocean Shader (II): testing ocean deformer shader


Octoplug Ocean Shader (II) - First test, ocean deformer shader





 I have followed the example provided by Silvestre Julien. See below the link in Vimeo.


I has taken me days to finish even though it is a very short video. I think it is simply aimed to more expert users of Maya. It was challenge for me to follow it, as I had so far escaped from the Node editor, and pretty much everything is setup here using the power of the nodes. But I ended up happy with the result, plus I learnt a little bit about the Node editor on the process. I have to recognize that I don't fully understand nearly any of the steps but I hope I'm able to replicate them when needed!

I'm hoping to be able to use this solution into the Fairy animation project, to simulate the waters of the canal.


Summary

 

The steps followed were: 

  • 1. Create a plane and adjust its size and grid. This will be used as reference. 
  • 2. Create a mesh on the Node Editor. This will be the mesh for the Ocean Surface.
  • 3. Create a Octoplug's Ocean shader on the Node editor. Connect the two shape nodes of the two meshes through the Ocean shader in between them. This will have created a dependency between the two surfaces, and we can see already the Ocean Surface with waves (more like spikes really) on it.
  • 4. Next you have to connect the <time> element to the OceanShader so that the geometry varies with the timeslider. At this point it will start to have some animation.
  • 5. Tweak the parameters to move from something brisk and spiky into something more similar to a sea wave.
  • 6. Test by playing.

Detailed Steps


Create a Polygon plane. 
      Resize the polyPlane: 25x25 size and 100x100 subdivisions.
 


Create a mesh:
    On the node editor, press TAB and search for Mesh
    Apply. It will have created a new shape, a plane (polySurface).
 
 
Create an Octoplug Ocean Shader in between the meshes
    Expand both meshes
    Connect the meshes through the OceanShader:
    From the WaterPlane's mesh to the Ocean Shader
        World Mesh[0] to the "In Mesh"
    From the OceanShader to the new mesh
        Out-Mesh to In-Mesh




This will have modified the shape of surface shape, so now is similar size and kind of waves on it.
    Renamed to <OceanSurface>   

 Now we add the <time> node
    On the outliner, un-tick <DAG Objects Only>

  
   Thank you Raziel:
   http://discourse.techart.online/t/how-to-connect-time-node-to-an-custom-attribute-in-maya/4228/2
   Drag it from the Outliner.
   Connect the time1 (<Time-Out>) to the Ocean Shader (<Time>).
   

Assign a Lambert material to the Ocean Surface
    Select the ocean shader and right click to Assign existing material

Let's play with the Ocean Shader parameters
    Change the Spectrum/ scale
    <scale> = 1.00 to <scale> = 25.00
    

 
    
    Wave/ Reflection and Scale
    Reflection: 0.00 to 0.5
    Align: 1.00 to 10.00
   

Let's play it, and it moves (waves)!

The Solution: Alembic Cache

Imagen
ALEMBIC CACHE INTRO Today I'll show the complete workflow for simulating the splash of water in Maya using Bifrost and then importing it into Unreal Engine. On the last episode our hero was left in a sea of doubts, wondering if he'd have to abandon the idea of simulating the water in Bifrost and start a singing career instead. Well, either that or finding a new approach for the water simulation. Actually I researched a few options to do the water splash simulation in Maya and found a few some interesting options. The most promising and similar in approach to Bifrost (use of particles) looked like NVIDIA Flex. I however didn't follow that path. I leave some links on the bottom if you want to explore it. Doing a short recap, I was stuck on how to export the simulation done in Bifrost to Unreal. The solution came from an option in the Bifrost Fluid simulation to convert the simulation into a mesh and using an export called Allembic Mesh. Thanks Michael Connolly for

Bifrost - Splash simulation (I)

Imagen
BIFROST - WATER SPLASH SIMULATION (I) Bifrost is a tool for Maya that allows for fluids simulation. Therefore it is related to physics. It was acquired by Autodesk in 2012. My purpose is exploring it in order to make a convincing splash of water on the animation project, particularly on the scene when the fairy falls into the wates of the canal. I have watched and read through some Bifrost material with mixed results. I have finally followed this simple video that finally allowed me as a valid starting point. The experiment simulates the splash of water produced by a rigid, heavy, sphere over a small water container. Youtube link to TunnelvizionTV's video that I have followed:  https://www.youtube.com/watch?v=BvZKiI1BEGk SUMMARY 1: Create a container Cube. 2: Create a liquid emitter. It will only be used to fill the container. 3: Create Bifrost Liquid (with the liquid emitter box selected). 4: Set the Cube as Collider , so that it is able

Water Research Simulation in Unreal and Maya - Summary and Conclusions

On this entry I'll try to summarize my experience with different water simulations techniques to date. Note that this is the result of a student's research only so please put big quotes on everything I'm saying. The techniques researched can be divided into two sections depending on the subject: -         Simulation of the water planes, for “static” waters. -         Simulation of “dynamic” water, for water splash effects. Also they can be divided depending on the technology: -         Maya -         Unreal Engine The most relevant techniques for the Animation Project were: -         Unreal Engine’s Starter Pack Water materials, for water planes. -         Maya’s Bifrost simulation combined with Mesh conversion and Alembic Cache export, that is imported as Geometry Cache in Unreal, for the water splash. The summary of techniques researched are as follows: Name Type Technology Comments Maya Ocean S
