The following is a list of features Unity added to version 15 of the Visual Effect Graph embedded in Unity 2023.1. Each entry includes a summary of the feature and a link to any relevant documentation.

### Ray tracing support
|
|
|
|
From version 15.0, you can use VFX Graph particles with the following ray tracing features in the High Definition Render Pipeline (HDRP):
|
|
- Ray-traced Reflections
|
|
- Refraction, Shadows
|
|
- Ambient Occlusion
|
|
- Global illumination
|
|
|
|
You can enable Ray tracing with VFX Graphs that use quads, triangles, and octagons. VFX Graph does not support ray tracing with meshes or strips.
|
|
|
|
To use ray tracing in an HDRP scene, refer to [Getting started with ray tracing](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@15.0/manual/Ray-Tracing-Getting-Started.html).
