Dynamo meshes not evaluated or displayed in Refinery study

Hi there,

On Revit 2021 version of Dynamo, I’ve been successfully importing a mesh (not from Revit) and using it to find the shortest distance between 4 fixed points and 1 variable point on that 3D surface.

When evaluating this Dynamo script in Refinery however, these calculations (output) from the mesh are not evaluated, and no mesh or surface is displayed in the explore outcomes window (see below).

Is this a known issue? Or does Refinery posess no capability yet to evaluate meshes?

Thanks!
