I have a model in obj format and want to load the model into
OpenSceneGraph. When there is no texture, OpenSceneGraph can load the

allocates a huge amount of memory and crashes. I think it's a runtime
bug and would like to know how to fix it. Please find some pictures
Not really a bug, I'd say you're running out of memory.
- try to reduce the image sizes.
- a lot of materials reference the same image. I don't think the obj
loader caches this which means you're loading that image over and over
again. Use osgDB::Options to specify caching of images.
Oh, and you seem to have pretty much one material per drawable. This will absolutely kill
your performance. Have a look at the .mtl file, you'll notice that there are heaps of
materials that have identical properties.
