obj Import problem

Hallo, I exported obj from KeyShot and can not open it in NVil.
Have this error:






obj:
https://drive.google.com/file/d/0B1uI4ljG15POX3M1X1AySVlNSG8/view?usp=sharing

Looking at the .obj file, it is using "Relative Vertex Numbering". That is causing issues in various 3d applications I use.

Is there an option in "Keyshot" to export .obj in "Absolute"?

Hay Steve,
Looks like there is no any setting for Export in KeyShot.
Also wanted to say that some files that I Exported from KeyShot, NVil opens without problems.
All that files I created with NVil.

For example this file I exported from KeyShot and it opens well in NVil.

Same error in Nvil.

The files appear to be the same, with the same download link.

If you open the obj file in a text editor, you will find two line like this

vn -1.#IND -1.#IND -1.#IND

It is a definition for a normal. But I don't know what means #IND.

If I change those two lines to

vn -1.0 -1.0 -1.0

It works.

Steve, sorry, this one:

vn -1.#IND -1.#IND -1.#IND

Good find.

That usually refers to Invalid Normals.

I made some changes. If invalid normal values found, the normal information will be dumped and NVil will generate new normals.
