Show in 3D Viewport is a function for selectively making the surface visible or not visible in 3D viewport.
Unlike Join in Simulation, it is not visible in 3D viewport but is included in the simulation.
This option can be enabled or disabled during simulation.
Surface > Right Panel > Properties > Pattern Properties > Show in 3D Viewport
- Select the surface in All / Curves Selection Mode.
- Enable or disable the function via Right Panel > Properties > Pattern Properties > Show in 3D Viewport.
- Enabling it will show the surface in 3D viewport.
Disabling it will not show the surface in 3D viewport.
