OBJ reading

Steps causing the bug to occur

  1. I have an OBJ file that appears correct in MeshLab, Blender, and other packages.
  2. When reading using the Fetch Scene node I seem to only get the 1/2 the model.
  3. I supply a minimal composition that illustrates the problem along with offending OBJ file.

Have you found a workaround?


Other notes

  • Vuo version: 1.2.6
  • macOS version: macOS 10.12
  • How severely does this bug affect you? It prevents me from completing a specific task with Vuo.

OK, it seems to be an OBJ size thing. The OBJ file I was using before had 256x128x2 (65536) faces. If I keep dropping the number vertices somewhere between 220x110x2 (48400 faces) and 230x115x2 (52900 faces) it stops working. The attached with 48400 faces works.
While I dislike (arbitrary) limits there may be good reasons. But should be documented (sorry if I missed it).

The limit was not intentional. It was introduced in Vuo 1.2.6 as an accidental side effect of some performance optimizations.

Until we get this fixed, a workaround is to pass the mesh through Flatten 3D Object (example attached).

Fixed in Vuo 1.2.7.
