I've been playing around with irrlicht lately and keep running into this problem with loading models where the particular side in which the camera is looking at will disappear and the model then doesnt look whole and solid.
In addition, the time it takes to load the application is like 30 seconds or more. Any ideas on how I could solve these problems or what I am doing wrong?
Looks like you exported the mesh with right-handed coordinates. This will "invert" the mesh, and hance backface culling etc. won't work properly.
The long loading types are rather untypical for 3ds models. How large's the file?
I got the model off of a free 3D resource site and it was somewhere in the range of a meg. The person who originally made the model probably didnt do something properly (as you stated) and I have since dumped it. Other models seem to be working as expected.
