Export multiple scenes from single blend file

[sdfgeoff]

For things like tilemaps, it is useful to export multiple scenes from a single blend source file. It would be nice to support this.

One way to implement this is that each parenting-hierarchy is exported as a different scene file

However, there are a couple issues that need to be worked through:

• [ ] Is each exported parent-tree centered to world origin? (I think yes)
• [ ] How are exported files named?
• [ ] How should data shared between files handled (eg materials)

Also to consider is that this makes integration with some build-systems hard, as you cannot know the output files, or how many of them there are until the export is completed. (For example, tup could not deal with this).

@ world origin recenter each "parental node" to the world origin on export

@ naming exportname_"parentalnode name".escn (so eg. "mytileset_wall.escn")

@ shared data export material als .tres and mark material as exported (simple dictionary/array), skip exporting material again if a material with the same name exists already.

Sounds too straight forward, so I surely missed something.

With Blender 2.8 stuff could get arranged in "collections". Might be a good starting point too (export collections as "scenes").

I'd like to have both options. So I can either export all selected Objects as their own scene or I can export the collections.

I don't think you missed anything significant.

I think I will have a look at the implementation and do a pull-request if successful.

I started the implementation: https://github.com/ModProg/godot-blender-exporter/tree/Export-by-Object Exporting by collection works.
