Geometry nodes - Convert scattered geometries to mesh

Support Modeling
1

Hi all,

I just started checking the new Geometry Nodes addition (great stuff, thanks to developers!), and I cannot find how to convert scattered objects to mesh (I don’t know if this is possible :thinking:). If I apply the Geometry nodes modifier, the scattered geometries dissapear.
Any help is appreciated, thanks a lot!!

Select the object that has the GN modifier on it and do a Object → Apply → Make Instances Real.
As usual with that operator, the newly created objects will be linked duplicates, so if you need them to be fully unique, you’ll then need to do Object → Relations → Make Single User → Object & Data.

Thanks a lot for your superfast reply @Stan_Pancakes! That worked fine! :smiley:

I’m not sure if this workflow works in Blender 3.0. I’m having this problem with BagaPie Addon since the beginning and I never figure it out. I believe Object-Apply-Make Instances Real isn’t an option. is that true? Please help. :slight_smile:

Hi @Stan_Pancakes
[Object → Apply → Make Instances Real] works to export but I can’t get the geometries with colors.
The model is exported with colors but the geometries are all white.
I’m applying random colors to the nodes using “Color Ramp”.

Any help?
Thanks

Thanks, I was just looking for this answer!

Actually, I must be doing something wrong… When I go to Object → Apply → Make Instances Real, duplicates a mini version of the geo output to each instance’s point…

Sorry to be impatient. I’m just hoping to get this solved so I can move forward. Just to summarize;

  • If use Object → Apply → Make Instances Real, it duplicates my object and the geo node out to every instance giving me tons of tiny clusters of the graph output instead of creating an exportable mesh.
  • If I use Realize Instances in the graph, I can export the mesh, but that node removes uvs
  • If I try to export without doing either of these I get nothing. Just an empty fbx. Surely there’s a way to get these files from blender to our respective engines.

thanks

Alright, actually think I’ve found the answer.
Step one, update to experimental build 3.1
Without using realize meshes or doing any conversion on your object/graph, File /Export / obj
Import the obj you just exported into an empty collection
select all the pieces and Ctrl J to combine them into one.
Export as fbx.

It’s certainly tedious, but seems to work.

In the version of Blender I’m using (3.2) I’ve found that if you add a “Realize Instances” node after “Instances On Points” and then apply the “Geometry Nodes” modifier in the modifier pane, then it seems to work!

Unless the object that the Geometry Nodes modifier is attached to is something like a curve, in which case, Blender does not let you hit “Apply” on said modifer. In that case, I’ve had to either, in the viewport, hit Ctrl+A and then “Visual Geometry to Mesh” or Object > Convert > Mesh after adding the “Realize Instances” node.
