ofMesh not rendering when extracted from model

@Evan_Clark wrote:

I have loaded a model using Asimp and have been able to select a mesh that is included in the fbx file. However when I call mesh.drawFaces() nothing renders. When I do this for the model it renders correctly and it is textured on all the meshes. If I use a texture bind the selected mesh does not appear either.

void ofApp::setup(){
    ofDisableArbTex(); //Need in order to get proper texture loading.
