    I am trying to use a random mesh from a short selection as a mesh output.
    The current method with a switch node is not working.
    "Can not link a GPU operator to a system wide (CPU) input."

    Any ideas? I would rather not create another emitter for each type.

    Thanks!

    Hello,
    The mesh slot on output is evaluated on CPU while your input graph is using a Random Per Particle which is only available on GPU. That's why this error is triggered.

    However, you can use the Mesh Count property and the Mesh Index attribute to dynamically choose on the GPU between four meshes.
