i have posted this before but now i'm desperate.Whenever i import a model into MED, be it in .3ds .obj .fbx or .x it works in the editor but not in the engine. i tried different file formats, different programs, and different ways of modelling.So i think the problem must be with MED. please help!

What do you mean by "it doesnt work in the engine" ?
Can you be more specific, and is the model showing a texture in MED?

Try to update your Video Card driver.

the model shows exactly how it is meant to in MED,textures and all, but when i do an engine preview it doesn't show up.

i used to convert my models via fragmotion to MED, and they showed up fine in the editor and engine.

even models i make in MED don't work, but fragmotion ones do.

have you tried changing the skin settings from 32 bit to 24 bit texture in the skin manager?

YES! it works now! i cannot thank you enough ryangregory! thanks so much! by the way, why is the default setting 32 bits?

Im not sure, I had this same problem a while back and had to figure it out myself. Its a real pain.
Anyway glad I could help.
