Particles can interact with environment in Unity.<br>
You can choose to interact only with static environment and build a "scene mesh" or use raycast for collisions but it will impact performances.

=Editor Scene Mesh=
To build a scene mesh in Unity's Editor :
# Add a [[PKFxSceneMeshBuilder component]] to an object in your scene<br>
# Expand "Game Objects To Search"<br>
# Drag'n'drop game objects with mesh renderers in their hierarchy to be used as scene meshes.<br>
# Enter a pathname (relative to pack's root) to save the built scene mesh to.
# Click "Build Mesh".
# On your camera's [[PKFxRenderingPlugin component V3 | PKFxRenderingPlugin component]] make sure you enable the scene mesh collision and enter the same pathname.

=Runtime Scene Mesh=
You can also build a scene mesh during runtime. It will create a PKFxRuntimeMeshAsset.
# Call PKFxManager.SceneMeshAddMesh() to add a mesh to the scene mesh.
# Call PKFxManager.SceneMeshBuild("Meshes/RuntimeScenemesh.pkmm") to build the mesh.
# Call PKFxManager.LoadPkmmAsSceneMesh("Meshes/RuntimeScenemesh.pkmm") to load the mesh.

=Raycast for collisions=
You can enable the raycast for collisions in the [[PKFxSettings_V3#Enable_raycast_for_collisions | PKFxSettings]]
