How can I export my spatial heatmap usable in Unity3D?

Hi to everyone. I’m trying to export my LB Spatial Heatmap result mesh to Unity3D.
I tried exporting by speckle, GH components to manage ‘display color’(but there was none) but it didn’t work.
I really don’t want to select every 4188 meshes and color(materialize) it by hand.
Can someone please tell me a better way to do this?

You can bake heatmap to Rhino. Then use rhino export colored mesh as FBX filetype.
