Export scene freezes under some formats.

[Lunci H]

I import a scene and trying to export it as obj or 3ds or some formats, AssimpNet freezes during exporting and stuck, no error message.

But if I choose to use the Assimp Binary format, the export works fine.

I attached the model I am testing. Import works fine.

Thanks for the report, I'll take a look

I just tested using the sample project, two workflows:

AssimpContext::ConvertFromFileToFile

Load using AssimpContext::ImportFile, then export scene using AssimpContext::ExportFile

Both worked in writing out an OBJ file of your robot model, and both pretty fast (tested in Release), and I can open the OBJ file in external viewers. Can you elaborate a bit more on what your code looks like?

I'm using my own code to construct the scene, so maybe there's some property not set correctly. I will try to figure out which property is.

Will let you know once found the issue.

Found the issue, because the Name in Material is null. It causes freeze.

Caused by Material.Name = null.
