I am having a problem with GetFirstMaterial with 9.5.
I broke my code down to the simplest form:

  
BaseDocument* doc = LoadDocument(fn,FALSE,NULL);  
if (!doc) return FALSE;  
BaseMaterial* mat = doc->GetFirstMaterial();

and mat is always NULL.
The debugger reports the value for mat\BaseList2D "CXX0030: Error: expression cannot be evaluated"

fn is a valid filename and does contain materials.

I am using vc6.

Is this a problem with 9.5 or am I missing a step or something?

Similar "LoadFile" but this time the document isn't put into the editors list of documents and you have control over the document_<_h5_>_> _<_h5_>_eturn

Unlike older versions without this argument, the loadflags look to be necessary. Have you tried SCENEFILTER_OBJECTS or SCENEFILTER_MATERIALS for the loadflags argument?

As I'm supporting older versions with older SDKs, I hadn't noticed this change (new to R9.5 for sure!).

LOL
I can't tell you how many times I looked over LoadDocument in the 9.5 sdk docs and never realized that "Bool show_error" had been replaced with "LONG loadflags".

Thanks guys. It's working now.
