Loading openbrush glb2 files

[arpu]

Hi,

i get some errors on loading openbrush glb2 files https://icosa-gallery.github.io/icosa-viewer/formats/gltf2/all_brushes.glb
error: ENOENT: no such file or directory, open '/tmp/https:/www.tiltbrush.com/shaders/brushes/OilPaint-f72ec0e7-a844-4e38-82e3-140c44772699/OilPaint-f72ec0e7-a844-4e38-82e3-140c44772699-v10.0-MainTex.png'

would it be possible to avoid the error and still to load the glb for modification

looks like this is not standard confirm and best solution is to export the model with included Textures in openBrush

Yeah, gltf-pipeline chokes on this GLB too, and gltfpack will run but omits all the textures. For security reasons I don't think any of these tools want to make network requests by default, and the files are at absolute URLs on the web.

In a script it would be possible to load the GLB, download the images first, update the image URIs in the GLB, and then continue processing with glTF-Transform. But even then there's the GOOGLE_tilt_brush_material extension present, so this isn't going to render with all the shader effects in any standard glTF viewer. Instead you'd get something like:

looks like https://github.com/icosa-gallery/icosa-viewer has done some work for this

newer version from openbrush includes the brush Textures so we do not need the extra Texture url download
