(Error report I saw every time I started my level in engine)
This caught me by surprise, as the build I used for Mystical Wings didn't have this. To start with I looked through all the settings in the 3DS Max exporter to see if there were any settings to change. Much to my dismay, I couldn't find anything, so I then began looking through forums to see if anyone has been having any issues. Thankfully I came across a post that described the method for changing the index format of the models:
The material issue I was having was just something left over from the way I set up the project assets. I managed to figure this one out quickly as I have seen similar issues in other engines. The material assigned to the model had a different name from the material created in engine. I'm changing them as I make update the files with the new index format. I'm also adding Physics Proxies (collision) to the meshes so players can't walk through walls. I'll make a short post about this process too.
Known problem resolved. Hopefully nothing else comes up between now and tomorrow evening.
