How to render thinkingParticles using the Particle Shader and Particle Texture


The video below shows how to use the Phoenix Particle shader and the Phoenix Particle Texture to read and render tP particles and custom data channels. This way, you can shade your particles based on their age, position — or any other custom data channel you have created inside of thinkingParticles.

Simulation with Phoenix FD using Autodesk Backburner


The video below shows how to run a Phoenix FD simulation using Autodesk Backburner.

Simulation with Autodesk Backburner

Click the Phoenix FD Simulator → Output rollout → Set output cache file location.

Start Backburner Manager, Server and Monitor.

Default Path: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Autodesk\Autodesk Backburner 20xx

In the Backburner Monitor go to Manager → Connect manager and set the corresponding IP address.

Click the Phoenix FD top menu → Submit Simulation to Backburner.

Set the name or the IP address for the Backburner Manager.

Turn on "Run only the Simulation and do Not Render".

Press the "Run" button.

 

How to use Phoenix FD Wetmap


 The video below shows how to use the Phoenix FD Wetmap.

Using Phoenix FD Wetmap

Click the Phoenix FD Simulator → Dynamics rollout → Enable "Wetting".

Click the Phoenix FD Simulator → Output rollout → Make sure that the Wetmap particles are enabled for export.

Open the Material editor and create two V-Ray materials.

Create a V-Ray Blend Material and connect the already created V-Ray materials as Base color and Coat 1.

Create a Phoenix FD Particle Texture → Select the Source Particle System → Select the Phoenix FD Simulator and pick the Wetmap particle group.

Connect the Phoenix FD Particle Texture as a blend amount mask for the V-Ray Blend Material.

Assign the V-Ray Blend Material to your geometry and render.

 

How to export a Phoenix FD cache to Alembic


The video below shows how to export a Phoenix FD cache to an Alembic file.

Exporting the Liquid Mesh

Set Phoenix FD Simulator → Export rollout → Export As: Mesh.

Go to File → Export → Export Selected... (with the Phoenix FD Simulator selected).

Under the Alembic Export Options dialog, make sure Extra Channels is set to UVW. Set the Animation → Range according to your needs.

Exporting Particles

Set Phoenix FD Simulator → Export rollout → Export As: Particles.

Select the Phoenix FD Particle Group in the Scene Explorer and go to File → Export → Export Selected...

Under the Alembic Export Options dialog, make sure Extra Channels is set to UVW. Set the Animation → Range according to your needs.

Importing through a V-Ray Proxy

Create a Standard Primitives → V-Ray → V-Ray Proxy and select the exported alembic file.

When loading a sequence of Alembic files, you can use the "#" symbol as a hint to V-Ray that the file path is a sequence. "C;\alembic_0001.abc' becomes 'C:\alembic_####.abc".

You can assign any V-Ray material to the imported alembic files.

 

In 3ds Max, while you have "Export as" set to "Mesh", the vertex velocity is in Map Channel 2 of the mesh, named "velocity". 3ds Max's built-in exporter names the Color Set in the exported Alembic file "Max_Map_Channel velocity".

Importing the Alembic file back into 3ds Max via the 3ds Max built-in Alembic importer requires you to set the "Velocity channel" to 2 in the V-Ray object properties dialogue, so you can render it with motion blur using V-Ray.

Importing the Alembic file in any host via VRayProxy will render with motion blur without any additional adjustments. It requires V-Ray Next Update 1.1, or newer.

 

Importing the vertex velocity of the Alembic file into Maya using Maya's native importer (Cache → Alembic Cache → Import Alembic) is not supported.

 

How to use Phoenix FD Surface Texture


 This video shows how to use the Surface Texture option inside of Phoenix FD.

Texture-Based Mesh

Set Phoenix FD Simulator → Rendering rollout → Surface section drop-down to Texture.

Click the No Map button and assign a texture (e.g. Cellular).

Make sure that Phoenix FD Simulator → Preview rollout → Show Mesh is enabled. The generated mesh should now be visible in the Viewport.

Tweak the Phoenix FD Simulator → Rendering rollout → Surface section → Isosurface Level parameter if necessary.

 

How to export a Phoenix FD simulation to OpenVDB


This video shows how to set the output format to OpenVDB and import the cached simulation inside of a V-Ray Volume Grid.

Exporting OpenVDB

Click the Phoenix FD Simulator → Output rollout → "..." button below the Simulation Cache Save Path option.

Select Browse and navigate to a preferred folder. Set the File Name option and choose OpenVDB (*.vdb) from the Save As Type drop-down.

Start the simulation as usual. The output cache files are now OpenVDB instead of AUR.
