Error after exporting from blender

[luisparravicini]

Hi, I'm getting an error after exporting with the Blender addon. Using the lighting example:

• Open lighting.blend (I'm using Blender 3.2.0)
• Go to the addon UI and click on "Tetra3D Export" (exported file: lighting.zip)
• Run the example (go run .). The output is:

panic: interface conversion: tetra3d.INode is *tetra3d.PointLight, not *tetra3d.Node

goroutine 12 [running]:
main.(*Game).Update(0xc00052e0c0)
	/home/xrm0/dev/a/Tetra3d/examples/lighting/main.go:96 +0xdfc
github.com/hajimehoshi/ebiten/v2.(*imageDumper).update(0xc000e2a190)
	/home/xrm0/go/pkg/mod/github.com/hajimehoshi/ebiten/[email protected]/imagedumper_desktop.go:111 +0x52

The line where the error occurs is:

        light := g.Scene.Root.Get("Point light").(*tetra3d.Node)

Is there something I should have done before exporting and because of that this error happens or is it a bug?

The only modification done in the example is to have exported the blender file.

Whoops, my bad, I never noticed this. This should be fixed with the latest lighting example; the core issue is that it's a point light, not a Node, so I've updated the lighting example with both a fresh GLTF export and a fixed main.go file. I've recreated the v0.8.1 tag/release with this fix. Thanks for the report~!
