Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Hi,
according with this page Sketchup needs <instance_node> and <library_nodes> section for instancing geometries.
Blender Collada Exporter does different and when I import in Sketchup the geometries are not instances anymore.
Is there a way to improve the export between the two softwares?
Thank you.

This sounds like a reasonable request.
I know it is easy to setup, but still it would help me a lot if you can add a simple model (blend file) so i have something to look at and be sure we talk about the same thing.
Also can you indicate in detail what you expect to see in the dae file and how it differs from what Blender does at the moment?
This would let me get started a lot faster :)
thanks
Hi Gaia,
Please find attached the blend file, the collada file exported from Blender (cube.dae) and the file modified by me (cube_mod.dae) which works as I expect. In the modified file I added few comments to show what I changed.
Thank you so much,
Luca

According to Collada the Node library is used for organizing scenes with many objects into manageable subgroups (see citations at bottom of page). If i understand correct, then your request introduces one library Node per instance_geometry. This adds one level of hierarchy to the exported data:
compared to what we have today:
The only solution i can see here is to add an export option for switching between "Export with instance_geometry" and "Export with instance_node". BTW the collada importer can handle both variants.
I have marked this report as "Design" and put it into my "feature request basket". Please let me know if you agree.
cheers,
Gaia
Hi Gaia,
Nice to hear from you.
You are correct: the node library is useful when there are repeated subgrups of objects: for example a repeated window on a facade.
I suppose that the solution you proposed can solve the problem.
Cheers,
Luca
