found exactly the same, couldn't think of any case where I'd use gltf extensions instead of custom props. custom props are simpler because you don't even need to run any python code to set them, you can do it manually and copy them around

i think it does have usecases, but more for when you have a bigger pipeline and you don't want to have to manually configure every file

if you already need a python script in blender to bake some data to custom props, and an import script in godot, this way could be cleaner i guess

Great thread, thanks for posting! (gives my open Unity instance the stink-eye)

does this really get you much of a benefit over just using metadata and an import script? probably not for most use cases

but, you can also modify the GLTF tree, store custom material properties etc.

store some UID for a geometry nodes live link addon, perhaps?

actually this would be good for storing stuff like hitbox activation and other function calls in animation data! since that's a pretty specialized thing, but being able to export markers or something for that would be neat hmmm

lateasusual.bsky.social•18 days ago

me, unaware: "oh boy i sure do hope the gltf exporter actually lets you customize animation stuff... maybe it doesn't"

the absurdly extendable exporter:

like i think there's something incredibly sexy about exposing hundreds of callback functions for users to put whatever code they want into. none of that "do everything in one post_export callback" nonsense :)

lateasusual.bsky.social•18 days ago

so, yes, making a GLTF exporter to let you use blender Markers as godot function call triggers - definitely doable

i don't have a usecase for it right now, but i'm sure many people would! so it would probably make a good example plugin if someone wanted to do that :3

that's wild

I would have never even considered that it was possible to call functions like that. feels like one of those niche use cases I would go insane trying to wriye code for and it's just easily available!
