Alle im Doku beschriebenen Objekt Formate kannst du als Mesh laden.
Und na klar kannst du da Kollisionen benutzen.. schau dir mal das Collision example an. Um ein sehr komplexes Mesh welches du zb. als level Grundlage erstellst mit einer schnellen Kollision zu versehen solltest du dieses wie oben beschrieben als "Octree" hinzufügen.
Wie Du das Machst.. siehe Irrwrapper Beispiel 04:

und zum Lightmappen und Szenen erstellen kannst du als Alternative zu Deled auch mal IrrEdit (
http://www.ambiera.com/irredit/ ) ausprobiern.
Nochwas irrlicht kann 4 Texturen pro Objekt laden, als Tip solltest du diese ned "verschwenden". Idealerweise benutzt du eine als "Diffusemap", "Lightmap", "Bumpmap", "Spec-Map" ... mit den 4 Typen kannst du Photorealistische Ergebnisse erziehlen .. aber zum Anfangen empfiel ich dir mal mit einer Textur pro Mesh zu arbeiten die du UV mappst ( Wings iss ganz gut dafür ).
Ausserdem achte drauf das deine verwendeten Texturen durch 8 teilbar sind .. typischerweise 128x128 , 256x256, 512x512 usw.
16 Bit texturen brauchen auch noch halb soviel Speicher ( den Grafikspeicher solltest du im Auge behalten ... Texturen brauchen jeweils die volle unkomprimierte Speichermenge im Grafikspeicher. Desto geschickter du mit Texturen etc umgehst desto schneller wird deine Szenery gerendert und speziell desto besser wird das ganze aussehen.
Hier ein altes Beispiel einer Kirche:
Und die UV gemappte Textur dazu:
Thalius
