So i have 3dgs a6 and every time i attempt to load a level in WED that has a 3d model that i created in MED, i get an error that the model is a bad mdl format. I dont understand the issue i was using the MED that comes with the Lite-c program so then i used A6 MED and the problem still occurs. This issue isn't happening when a use a model downloaded from the web or ont htat i had to convert in MED. any help would be apprecitated.

and what kind of error?

e1302 bad mdl format.

It may be a simple solution like resaving them.

Try resaving the file as both a model 7 and a model 5 then see if you can see them ingame again.

Lite-C's MED saves them in a format not compatible with A6. You'll need to use the A6 MED.
