acces violation when loading a FBX model with no content.

[Christian Clavet]

Hi, A user reported a problem importing from FBX model. He sent me the model to check.

 

I opened the model and there was NO geometry inside it (imported inside 3DS MAX, since I pre-ordered Leadwerks 3.1), the user reported an access violation and crash from LE editor when he tried to import the file.

 

Here is a link to the thread

Here is the model

 

The probable cause of this could be that LE is trying to get the geometry and get to the end of file.

 

How to reproduce:

import the provided FBX model inside the Leadwerks editor.

 

Reproducibility rate:

From the user report 100% reproducible. (Check the thread for more details)

 

I helped a little bit the user to export models from Blender in FBX and now the models work correctly. So exported scenes in .FBX that contain geometry will not create the problem. Please use the provided file to reproduce the problem.

 

By the way the web site is incredible! I was surprised that we could chat directly and exchange files from the site!

So the problem is that an empty file that contains no geometry causes a crash?

I changed the loader so that if the file contains no objects it will return NULL when Model::Load() is called.
