So close.. yet so far away..

Ok i've made additions to materialPropertyMap to allow for a normal map to be loaded for interiors (following the code for enviroment maps).

pEntry->normalMapName = StringTable->insert(pColon);

and created an sgNormalMapPolyList to hold the geometry associated with the normal map.

in interior.cc (prepforrendering)I have

mNormalMaps[i]    = new TextureHandle(pEntry->normalMapName, InteriorTexture);

after this line executes nMormalMaps[i] holds "texture_normalmap" (which is my normal map specified in propertymap.cs)

but where do i actually load the file? because when i do a getGLName in interiorrender (rencerARB_FC):

glBindTexture(GL_TEXTURE_2D,mNormalMaps[sgNormalPolyList[i]]->getGLName());

i get a bad ptr..

any clues what i am missing?
