How does one go about doing that? I tried to bring it into Substance Painter and it doesn't see the individual meshes. I've tried other obj's created in different apps and they come in fine, but not the ones created in Houdini.

I've tried the whole Connectivity + Partition sop deal but that doesn't work either https://www.sidefx.com/forum/topic/16747/?page=1#post-78831 [www.sidefx.com]

I'm sure there must be a simple solution here.

Or, as an alternative how would you do it in FBX? Same problem there, no individual mesh pieces, just one big mesh exported.

The only one I know how to do properly is ABC files, but Substance Painter doesn't recognize those….

Thought I had some answers but everything I tried didn't work.

Thanks

Hi, I posted a while ago regarding Substance and whilst the info might be a little old, most of it still applies. https://www.sidefx.com/forum/topic/52609/#post-236500 [www.sidefx.com]

In short, Substance will import and split the model based on materials so if you want individual meshes, apply a different material to each.

You will need to use FBX as Houdini doesn't natively support the mtl files needed for obj material assignments. Sidenimjay did upload a tool as a workaround though. https://www.sidefx.com/forum/topic/42169/?page=1#post-189542 [www.sidefx.com]

Super awesome… WORKS! Thank you so much.

This doesn't work for Unity.
Is there a way to split it according to groups or attributes?

When importing an fbx Houdini itself gives each fbx mesh the detail string attribute ‘name’.
This attribute also defines the hierarchy: ‘/transform1/mesh1’.

Is there any chance this could happen?
It is a very tedious process to create new geometry nodes and within them object merges every time you add a small mesh.
