Exporting 3D voronoi fragments as group of individual objects

Rhino
1

Hi all -

Been working on 3D voronoi in Grasshopper, etc.

Have baked my fractured pieces in Grasshopper…

I am now trying to export the group of fragments as OBJ or similar.

WHat I want at the other end is a set if individual meshes (the fragments) that I can then apply physics to.

However, every time I export (have tried a selection of polygon meshes->OBJ; polygon meshes to FBX; and polysurfaces->FBX), the individual fragments are not selectable.

What am I missing/failing to do in my workflow?

Thanks!

Hello- can you test this one in your process? There should be six independent meshes - in Rhino it does open that way, it may be that in your target application there are import settings to pay attention to.

@Hedders can you post a small example of what you are trying to export?

Here you go…image of source Voronoi pieces once baked in Rhino.
Next to it is image of OBJ imported into Unity.
Note that when i do…there are no sub-meshes.
I attached the Obj I tried, using your suggested tweak.

Thx,

Hi Hedders -

When I import that file into Rhino, it looks like this:

You’ll have to look at settings “at the other end” to have that come in as separately selectable objects.
