Creating a Node Tree

Creating a Node Tree and adding nodes to that Particle Node Tree exactly like in the way you do it in Shade Editor.



Exploring Phenix Stack Features

As you create Node Trees, they seamlessly integrate into the Phenix Stack, offering a centralized hub for managing your particle animations. Here’s a guide to exploring and leveraging the features within the Phenix Stack

Icon Functionality



Camera Icon:

The Camera Icon offers a convenient option to manage the visibility of the selected particle animation in the 3D Viewport.


Here’s how you can use it:

  • Left-clicking on the Camera Icon allows you to toggle the visibility of the selected particle animation within the 3D Viewport.
  • When activated, the animation becomes visible, providing a real-time preview of its effects on your scene.
  • To conceal the animation and focus on other aspects of your scene, simply left-click the icon again.


Pencil Icon:

In Phenix, selecting a node tree doesn’t automatically put you in edit mode. To make modifications to a node tree, you need to utilize the Pencil Icon.


Here’s a clear explanation:

  • The Pencil Icon serves as an indicator of the edit mode for a specific node tree in Phenix Particle.
  • Simply clicking on the Pencil Icon activates the edit mode for the chosen node tree, allowing you to make adjustments, add or remove nodes, and refine your particle animation setup.
  • Ctrl + Click: Turns on the visibility of the animation for the selected node tree, simultaneously turning off the visibility of the animation for the previously active node tree.
  • Shift + Click: Turns on the visibility of the animation for the selected node tree, leaving the visibility of the animation unchanged for the previously active node tree.
  • This ensures that modifications are intentional, providing a safeguard against unintended changes while navigating through node trees.


Cross Icon:

The Cross Icon in Phenix offers a straightforward way to delete a node tree.



NOTE: Any modifications made to the Node Trees or their individual nodes take effect when you play the animation from the beginning. This ensures that you observe the real-time impact of your modification in the 3D Viewport.


Exploring Tree Tool Features



Uncover the capabilities of the Tree Tool in Phenix, a feature designed to streamline node stage management for selected nodes. Utilize the Tree Tool to conveniently set node stages for selected nodes, enhancing control over the simulation process.

Node Snippet is your go-to resource for accelerating your particle animation projects, offering flexibility, collaboration possibilities, and efficient management of your creative assets in Phenix Particle.




Baking the Particle Animation

Before initiating the particle animation baking process in Phenix, ensure you follow these steps for a smooth experience:

Save Your Blend File:

Begin by saving your Blender project file to secure your progress.


Un-Mute the Bake Particle System Node:

If the Bake Particle System Node is muted (if it is, the node will be greyed out), unmute it by pressing the ‘M’ key on your keyboard. This ensures the system is ready for baking.


Set Path in Bake Particle System Node:

Access the Bake Particle System Node and set the desired path for the animation bake. This defines where the baked data will be stored.


Enhanced Control Options:

For more control over the baking process, select the Bake Particle System Node and navigate to Node Properties. There, you can add attributes to bake according to your preferences.


Initiate Baking:

To commence the baking process, simply play the animation from the beginning. Phenix will start baking the particle animation based on your configured settings.



Final setting for Rendering the Animation

As you approach the final stages in Phenix, prepare for rendering by making a small adjustment in the modifier. as illustrated in the GIF


Here’s the reasons you need to do this manually at the end:


Render Optimization in Cycles:

Phenix Particle is optimized for rendering billion-point clouds in the Cycles render engine. Leverage this efficiency when working with extensive particle setups.

Eevee Considerations:

Note that the optimized cycle setting may not be supported in Eevee. In such cases, instances or alternative models can be used to achieve performance with reduced computational demands.

Instance Replacement:

Consider replacing mesh instances with lightweight models, such as a fly model for intricate patterns or a bird for boid FX simulations. This helps balance performance and visual impact.

Integrating Rotation Nodes:

Introduce rotation nodes within the particle graph and bake rotation attributes for instances. This enhances control over the orientation of the instances, crucial for achieving specific visual effects.

By understanding these considerations and manually adjusting settings as needed, you tailor Phenix Particle Animation to meet the specific demands of your particle animation, rendering efficiently across different scenarios and rendering engines.
