It seems that trying to import this .obj file (in babylonjs sandbox), it can’t be read and I can’t understand the error in console. It works fine in other 3d viewers.
The error is the following:
solidParser.ts:212 Uncaught TypeError: Cannot read properties of undefined (reading ‘x’)
at e._unwrapData (solidParser.ts:212:76)
at e.parse (solidParser.ts:745:22)
at e._parseSolid (objFileLoader.ts:242:21)
at e.importMeshAsync (objFileLoader.ts:156:21)
at e.loadAsync (objFileLoader.ts:178:21)
at f (sceneLoader.ts:571:13)
at o.onload (fileTools.ts:369:9) aaa.zip (1.1 MB)
the expected format here would be the f 1//1 2//2 etc...
The other viewers are probably trying to fix this under the hood by assuming that, if you have a face in the f 1/1 2/2... format, but there are no UV coordinates, then the second index refers to the normals instead of the UVs. Should we do the same @sebavan ? We could perform this correction by default, or throw an error in the default case, and pass an option to correct.
That would be the cherry on the cake Though, I think the current behavior is quite expected. No UV, no tex projection == no money, no candy, no cando I actually encountered this before while being careless with my assets and in fine, I’m fine with it the way it is (of course, personal opinion only).
